Even a Yato Can't Pursue Our Teacher!

[Complete Gintama fanfic] Is Being a Teacher's Wife a High-Risk Occupation Now?! / Don't Underestimate a Kabukicho Widow! [Upcoming Gintama fanfic] We're Just JOY Buddies After an accident while saving the world, Kira Matsuzakura opened her eyes in a parallel world. Here, many people were shocked when they saw her face, then became exceptionally well-behaved. She later learned she looked exactly like their dead teacher. Matsuzakura: The version of me in this world seems to have had a rough time. But aren't we immortal Altana mutants? * While standing up for the women of Yoshiwara, Kira Matsuzakura ran into a strange young man. The leader of the Harusame Yato became intensely interested in her after watching her fight Yoshiwara's tyrant, and he spent every day asking to fight her. Matsuzakura was at a loss. Then the little rabbit suddenly became the new boss of Yoshiwara. One minute he was inviting her into space, the next he was giving her a huge sword. In everyone else's eyes: A terrifying pirate boss is about to kill someone. In Matsuzakura's eyes: A little rabbit hopping all over the place and chattering nonstop. But after a while, everyone began to notice something was off. Why did the boss smile while plotting against others and beat them up, but act sweet, innocent, and eager to learn in front of Matsuzakura? Coworker: Does the boss have a crush on you? Matsuzakura: (horrified) We're way too far apart in age! Coworker: Come on, younger-man/older-woman couples are all the rage now. Matsuzakura felt tears welling up inside. Girl, do you know I've lived for thousands of years... And I'm not human! (Umibozu: So what?) * Matsuzakura's original goal was to return to her own world. She had a vague sense that if she met the version of herself in this world and triggered another burst of Altana energy, she could open a portal through time and space. --Who knew her counterpart in this world would not only be a man, but also an early-dead beloved and the final boss?! --Wait, why are you trying to destroy the world, too?! She might not belong to this world, but she could hear the earth wailing and see the people she loved in despair. Matsuzakura decided that even if she died from running out of energy, even if she could never return to her own world, she would fight to the end. But the little rabbit didn't feel the same way. * He still remembered the day they finally fought, when she beat him until he couldn't move. She let him rest his head on her lap, stroked his hair, and gazed at him with loving eyes, her touch gentle. Though he was in her arms, it felt as if an unspoken, unbridgeable abyss still lay between them. It made him think of his mother, who'd been immortal until love brought about her death. "Matsuzakura... Why are you so strong? It's like you'll never be defeated..." Kira Matsuzakura lowered her head and whispered into the boy's ear: "Shh, I'll only tell you." "It's because I'm the incarnation of Earth's Altana energy. Just not this planet's." Kira Matsuzakura didn't see the boy's pupils contract sharply. [He finally realized that the greatest source of his sorrow and shame was that he was exactly like the father he hated and despised.] [They had both hopelessly fallen in love with a powerful, beautiful spirit of Altana, begging that eternal being to stay with them for a brief moment, and hoping to carve a mark of their existence into her infinite life.] * Kira Matsuzakura knew nothing of the little rabbit's feelings. In the final battle, she chose to use her last reserves of strength to perish together with her counterpart in this world. --To go home, or at last find death. Only after the world fell into chaos and she was forcibly awakened did Matsuzakura learn that the rabbit, who was countless years younger than she was, was the child of her old friend in this world. And the little rabbit's obsession was this: He would never again let an incarnation of Altana like his mother die. Even worse, her students from her original world had crossed over, too. Under the powerful yearning of people from both worlds, the portal through time and space opened once more. * That day, facing a disaster-level love triangle, Kira Matsuzakura grew up. Why is the teacher's storyline so dangerous? Why is the younger rabbit so crazy? *Matsuzakura's story presents another possibility: a female Altana mutant from Earth. She's like the parallel-world counterpart of San-san, but they are not the same individual or a simple gender-swapped version. Their different experiences have made their personalities quite different, so please don't treat them as the same person. *The characters in other parallel worlds also differ somewhat from their original counterparts. Some names have been changed or replaced with homophones. *Some timelines and plot points have been changed. *Absurd comedy, with no concern for keeping characters in character. *The heroine has a universe-class T0 combat rating, is beloved by everyone, and is a Mary Sue. *To avoid misunderstandings, the female and male leads are not teacher and student, lol. Theme: Love is a light that illuminates all the darkness in life.
