When she was three, Haruno Hoshi dreamed of a strange white ball of light.
White Ball of Light: "I am the consciousness of this planet. A thousand years ago, the alien Otsutsuki invaded and drained my power, turning it into a Chakra Fruit to consume, but I did not die. After I awoke, I used the last of my strength to summon you, a being of cosmic energy. A great power sleeps within you.
The Otsutsuki crisis is not over. I have sensed the future in which this world is about to be destroyed, but I can no longer do anything. I hope you can save this world. Once I awaken successfully, I will give you some of my energy in return and appoint you as its savior."
Hoshi: (I don't understand, but I heard the words "save the world." ) "Okay!"

After waking up.
Hoshi: "Mom, Dad, I've been chosen to be the savior!"
The Harunos: "Hoshi-chan is amazing! Mom and Dad are so happy!" (Kisses, hugs, and being lifted into the air.)
Kizashi Haruno: ? (My little sister is saying strange things again.)

After starting school.
Hoshi: "My dream is to save the world!"
Obito: "Hoshi-chan is amazing!" (Starry-eyed.)
Rin: "Do your best, Hoshi-chan! I'll always support you!"
Guy: "That's so passionate! I need to work even harder too!!!"
Other classmates: "Haruno-san is so cool!"
Kakashi: ... (Am I the only normal person here?)
Later, when Kakashi sees Hoshi open a black-hole-like abyss of a mouth and suck everything in, his eyes widen.
Everyone: "You could have conquered the world outright, but you chose to save it instead. I'm crying."

She originally only wanted to grow up and inherit the family sweets shop, but somehow ended up on the path to saving the world.
Also known as The Would-Be Savior Who Accidentally Unified the Shinobi World, That Pink Demon Charges In Shouting About Love and Bonds, and She Ate Her Way Through the Entire Shinobi World to Get Stronger.
P.S.
1. The heroine is naturally airheaded and straightforward, the ceiling of combat strength, and overflowing with a sense of justice. So righteous she's practically wickedly good. (To her enemies, she seems like a demon, with an innocent cruelty.)
2. A beloved-by-all story, with lots of one-sided crushes. The heroine doesn't get the hint. Everyone is my one and only, JPG.
3. The heroine's abilities are inspired by Kirby. She has an "Abyssal Maw" and can gain the corresponding ability by eating something, at a level higher than the original.
4. The heroine is a being of cosmic energy, drawn into the Ninja Planet by the world's consciousness and born into the Haruno family. She is Kizashi Haruno's younger sister, eight years younger than him, and the same age as Kakashi.
