I feel like all of these are fine. The stories are all exciting, some have single heroines, some have multiple heroines, and the writing is good and beautiful.
I recommend a book I wrote, which contains basically all the female protagonists. Anyone who is interested can come and read it. This is a chapter of the worldview of my book: Chapter 30 (Must read!) [Easter Egg Chapter] The battle of seals thousands of years ago, the beginning of the fate of the two worlds The energy system of the Pokémon world is composed of two core forces - one is the elemental attribute energy, which Pokémon condenses through practice and turns into various moves such as fire, thunder, and rocks, which is the basis for the operation of the world; the other is the more mysterious and powerful breathing energy, and this energy has always been monopolized by one breathing method for a long time - the pure and noble dragon's breath. There are only two parties who control the Dragon's Breath: the mythical beast with dragon attributes, and the "Dragonborn Organization", a righteous human organization hidden behind the scenes. Dragon-type beasts are born with the breath of the dragon, and can fuse it with their own moves to burst out with devastating power. But not all dragon-type beasts are content with their destiny. Some of them regard themselves as noble and believe that they should be superior to humans and ordinary Pokémon, and have repeatedly tried to conquer the world with the Dragon Breath Fusion Technique. In order to protect peace, the Dragonborn organization came into being. They are the embodiment of justice and fairness, and master the ultimate fusion method unique to dragonborn: members of the organization all have pure dragon hearts, and can establish soul bonds with dragon Pokémon that also understand the dragon's breath, so as to realize the fusion of human and pet, and the fusion of human and pet. When a person and a Pokémon are connected in mind, the power of the bond will catalyze the dragon's breath, releasing the human-pet fusion dragon's breath combo! Erupting with terrifying power that can surpass the beast. It was this deterrence that forced those restless dragon-type beasts to curb their ambitions. The Dragonborn organization has thus become the secret guardian of the balance between humans, Pokémon and mythical beasts, silently guarding the peace of the Pokémon world in unknown corners. On the other side of the Pokémon world, the Demon Slayer world is a sub-world of each other. The two worlds blend and coexist, but they always adhere to the boundary wall and do not interfere with each other. Only those with a sincere heart, strong unwillingness and obsession can break the constraints of the boundary wall and achieve cross-world travel. This peace lasted until the appearance of Dark Kyurem - purple-black thunder tore through the sky and illuminated the ancient continent of the Pokémon world pale. Arceus is suspended above the clouds, with its colorful wings spread out like a river of stars that covers the sky and the sun. The sacred energy flowing around him resonates with the heaven and earth, and every breath stirs up light particles all over the sky; on the plain below, the Dark Chieftain Rem is entrenched like a majestic ice dragon fortress, with its pitch-black scales glowing with cold darkness, and its ice-blue pupils burning with all-devouring dark flames. Wherever the dragon's breath passes, the ground freezes into a frozen purgatory with no vegetation. "Arzeus, you are trying to prevent the darkness from coming, but you are overestimating your capabilities!" Dark Kyurem's roar shook the mountains and rivers to collapse, the ice dragon's claws hit the ground, and countless ice spikes broke out of the ground, piercing the God of Creation in the sky. "This world should have returned to chaos, and only darkness is eternal!" "Your existence is a crack in the balance of the two worlds." Arceus's voice was calm but with unquestionable majesty, and the colorful energy condensed into a bright ball of light in front of him. "The Pokémon world and the Demon Slayer world are mirror images of each other. They blend and coexist but cannot interfere with each other. Your dark energy has already penetrated the boundary wall and polluted the foundation of the two worlds." Before he finished speaking, Arceus waved his wings, and the colorful light balls turned into countless light blades, hitting Dark Kyurem like a meteor shower. Dark Kyurem roared and breathed out the extremely cold dragon's breath. Ice and light collided violently in mid-air, erupting into a devastating energy shock wave that flattened the surrounding mountains. At this moment, dozens of golden beams of light suddenly lit up at the edge of the plain, and the ancestors of the Dragonborn organization came galloping over on various dragon Pokémon. The old man at the head was wearing scale armor, holding a long staff inlaid with dragon crystals, and was surrounded by a thick golden dragon aura. He was the leader of the first generation of Dragonborn. The members behind him were connected to the auras of their respective dragon Pokémon, and the golden dragon breath energy intertwined into a huge barrier, firmly trapping Dark Kyurem's dark energy. "Dragon's Breath: Resonance of Hundreds of Dragons!" The first-generation leader shouted loudly. People and Pokémon activated the breathing method at the same time, and the golden dragon energy turned into a giant dragon shadow and rushed towards Dark Kyurem. The core mystery of Dragon's Breath lies in the "fusion of humans and pets": only humans with a pure dragon heart can establish a soul bond with a dragon-type Pokémon that also masters Dragon's Breath, in order to completely integrate the breath energy with the Pokémon's power, and display a hybrid Dragon's Breath that can shake the world. The Dragonborn organization is the secret guardian that protects this power and maintains the balance among the three parties. Dark Kyurem roared upon seeing this, and the dark energy around him surged, tearing apart part of the barrier: "A bunch of ants, how dare you stop me!" It swooped down, and the ice dragon's claws grabbed the Dragonborn organization's formation, but was severely hit by the "Dragon Breath Meteor Break" after the first generation leader merged with Kuailong, and his huge body staggered in the air. "Lord Arceus, let's help you!" The first-generation leader shouted loudly, "Dragon's Breath, Human Pet Fusion, Ten Thousand Dragons Destroyed!" Dozens of golden light beams suddenly gathered, and the figures of people and Pokémon gradually overlapped, turning into dozens of golden dragons, intertwined with Arceus's colorful energy, forming an energy beam that penetrated the sky and the earth, and slammed into Dark Kyurem. "No—!" Dark Kyurem let out a shrill roar. Dark energy and light dragon energy collided violently in its body. Its scales continued to peel off, and the ice dragon's body gradually collapsed. But it was a legendary dark beast after all. When it was about to die, it burst out with its final dark energy, hitting Arceus in the chest. At the same time, a dark tentacle pierced the shoulder of the first generation leader. The light on the colorful wings of Arceus dimmed instantly, and a mouthful of golden blood spurted out from its mouth, falling to the ground and turning into a sea of golden flowers. The ancestors of the Dragonborn organization also suffered heavy casualties. The first generation leader barely stood firm with the support of the fast dragon, and the barrier of the Dragon's Breath was crumbling. Dark Kyurem's body is on the verge of collapse, but the dark flame in its eyes is still undying: "Although I am defeated, darkness will eventually return... By then, both worlds will become my possession!" Arceus held on to his injuries, and the colorful energy turned into chains, tightly binding Dark Kyurem's body and sealing it deep in the heart of the ancient continent: "In the name of the God of Creation, I set an eternal seal... Unless the dark energy of the two worlds resonates, you will never get ahead!" After doing all this, Arceus' aura became weaker and weaker. It knew that it was seriously injured and must fall into sleep to recover, but the threat of Dark Kyurem always existed. Its gaze penetrated the boundary wall and looked at the Demon Slayer World that merged with the Pokémon world - it was in the dark age when humans and ghosts coexisted, but there was a group of humans who relied on breathing techniques to fight against the immortal evil ghosts. The will of one of the human leaders caught Arceus' attention. That is Thousand Dou Jin. At that time, Jin was still a stranger who had traveled to the world of demon destruction. He lost his memory before time travel, but with his indomitable will, he rose to prominence in the Demon Slayer Corps, understood the Breath of Thunder, and eventually grew into one of the top three pillars in terms of strength. But he gradually discovered that the evil spirits in this world were completely different from what he had imagined - Wu Mei's power far exceeded the legend, and he could even perform strange moves that caused rocks to collapse and flames to set fire to prairie fires. Those moves contained vague fluctuations of Pokémon energy (this was the trace of the fusion of the two realms, but Jhin knew nothing about it at the time). He spent his whole life fighting against evil spirits. His partners fell one by one, and important people left one after another. In the end, in the decisive battle with Wu Mei, he burned up his breathing energy and died together with Wu Mei, but failed to protect anyone he wanted to protect. The strong unwillingness, unyielding will, obsession for revenge, and the sincere heart that has never been contaminated by darkness penetrated the boundary wall and was captured by Arceus who was about to fall asleep. "You are the successor of the prophecy." The will of Arceus came and pulled Jhin's soul out of the void of the Demonic World. "I will give you a chance to come back to the Pokémon world, master stronger power, make up for your regrets, and protect the balance of the two worlds." Arceus turned part of his will into an exchange system, embedded it deep in Jhin's soul, and reshaped his body in the Pokémon world. Just so that he could start over in a new world, Arceus temporarily sealed his memory. This time, it will be twenty years. It wasn't until Jhin awakened the Breath of Thunder and the Breath of the Sun in the Yew Research Institute, and his memory and system were unlocked, that he knew his fate - to save enough points, return to the Demon Slayer World to make up for his regrets, and at the same time, he had to face the darkness that was about to return. On the other side, the Dragonborn organization in the Pokémon world has also experienced a turning point in its fate. Longze, the leader of the contemporary Dragonborn organization, is the most talented successor to the Dragon's Breath in history. His Dragon's Heart is pure and flawless, and his combined skill with the Biting Land Shark "Dragon's Breath: World Breaking" is unrivaled in the world. When he read the prophecy in ancient books that "Dark Kyurem is about to break through the seal," he took Liebite Land Shark alone to the sealed cave deep in the earth, hoping to strengthen the seal in advance. Deep in the cave, dark energy filled the air like thick fog, and several cracks appeared in Dark Kyurem's sealing chain. Long Ze clenched the dragon crystal staff in his hand, and the golden dragon energy around him surged: "Bite Land Shark, prepare for the combination of Dragon's Breath and Human Pet, and strengthen the seal!" "Roar——!" Lie Bite Land Shark echoed, fighting spirit ignited in his red eyes, and the golden dragon's breath energy was connected with Long Ze's breath. But at the moment when the combined energy was about to condense, the sealing chain suddenly cracked open, and Dark Kyurem's ice-blue pupils suddenly lit up, and a purple-black dark energy column shot straight into Long Ze's eyebrows! "Not good!" Long Ze's pupils shrank suddenly, and he wanted to activate the dragon energy to resist, but found that the dark energy invaded the body like gangrene on the bones, spreading along the blood to the limbs and bones. The cold whisper of Dark Kyurem sounded in his mind: "Give up your resistance... Your dragon heart is very pure. As long as you surrender to me, you will gain stronger power." "No... I am the leader of the Dragonborn. It is absolutely impossible..." Long Ze clenched his teeth, veins popped out on his forehead, and the golden dragon energy and dark energy collided crazily in his body. "I want to protect the world... And cannot be swallowed by the darkness!" He tried to mobilize the dragon's breath to dispel the dark energy, but the power of Dark Kyurem was far beyond his imagination. The energy was controlled by a strong will, constantly eroding his mind. "Guarding the world? You're just deceiving yourself." Dark Kyurem's voice became more and more bewildered. "Look at this world, the battle between humans and Pokémon has never stopped. Divine beasts are high above. Only darkness can bring true 'balance'." Long Ze's eyes began to waver. The oaths of the leaders of the Dragonborn organization to protect the world flashed through his mind, and the beliefs he had adhered to for many years flashed back. The two wills violently clashed in his mind. His body trembled uncontrollably, the golden dragon energy was gradually eroded by purple and black, and his red eyes began to become bloodshot: "I... Can't..." "It's useless." Dark Kyurem sneered, "Your will is vulnerable to the absolute power of darkness." The dark energy completely exploded, Long Ze let out a painful roar, his body arched suddenly, and the dragon crystal staff in his hand broke with a "click". Dark energy invaded along his broken dragon crystal staff, and his fingertips gradually turned black. The dragon's energy twisted into purple-black vines as he roared. His eyes gradually became hollow from struggling, and the golden dragon's energy around him was completely replaced by purple-black. The originally pure dragon's heart was tightly wrapped in dark energy. "Follow your orders, my lord." Longze returned to the Dragonborn organization with the blackened Liebite Land Shark, and began to secretly use dark energy to blacken other members. His actions were extremely covert, and it was not until a large-scale blackening ceremony that the Great Elder Ao Qiong noticed something was wrong - the old man with the second most powerful dragon's breath in the world had already noticed the dark fluctuations in the leader's breath. He led some determined and powerful members and rushed out of the Dragonborn organization's headquarters with all their might. The Dragonborn organization split. The righteous dragonborn faction headed by Ao Qiong adheres to the original intention of protecting the world. According to the prophecies in ancient books, they began to look for "a leader with alien breathing energy" - the prophecy said that when darkness comes again, this leader will lead humans and Pokémon to expel darkness and correct the mistakes of the world. The Dark Dragonborn faction headed by Long Ze has become the minions of Dark Kyurem. They are also looking for the holder of the alien breath, but their goal is to obliterate the other party and dedicate their breath energy to Dark Kyurem to help it completely break through the seal and at the same time strengthen their own Dark Dragon Breath. An overt and covert struggle spanning more than ten years has begun. The fate of both worlds depends on the boy who has just awakened his memory. When Jhin fought fiercely with Sakaki in the Viridian Gym, when his breath of thunder continued to merge with the power of Pokémon, in the sealed cave deep in the heart of the earth, Dark Kyurem's ice-blue pupils suddenly lit up, and a cold smile appeared at the corner of his mouth. "The holder of the alien breath... Has finally appeared." "The day has finally come for me to return to the world!!! Ah, this thousand years has been so difficult!" "Hmm, Arceus, you didn't expect me to come back to the world, right? Having absorbed the energy of the alien breath, I am resurrected again, and I will be unstoppable! And you who are still seriously injured, what can you do now? Hehe..." "Arceus, I will "repay" you for this thousand years of loneliness..." "Let's take your most loyal subordinates first, Phoenix King and Lugia, and let's do it~ Hum hum hum..." The dark energy has spread along the boundary veins to the top of the rainbow. On the sycamore tree where Phoenix King rests, black lines are quietly climbing up. When the Phoenix King spreads its wings, the black feathers on the wingtips have increased from a few pieces to a cluster. You can even feel the dark energy pulsing faintly under the feathers, and a trace of uncontrollable scarlet flashes in its eyes. It lowered its head and rubbed the eroded tree trunk, feeling a little helpless and remorseful in its heart. Finally, King Phoenix closed his eyes and muttered in his heart: "Oh, I am really useless. No matter how I feel, I can't master the dragon's breath to help Master Arceus share some of the pressure; no matter how hard I try, I can't stop the darkness from spreading throughout my body... Leader, I hope I can stay awake next time we meet." Elder Ao Qiong of the Justice Dragonborn Sect stood on the treetops of Viridian Forest, looking at the thunder in the direction of the gym. A trace of relief and solemnity flashed in his eyes: "He is the leader in the prophecy. Young leader, you must grow up quickly..." The shadow of darkness is spreading quietly. The fateful battle between the two worlds is about to begin.
