During a certain voyage across the star sea, Yetu Shenzhou's spaceship was caught in the turbulence of time and space, and all the controllers collectively failed.
The spacecraft encountered a serious malfunction and issued a strong danger alarm. For his own safety, Shen Zhou lay down in the emergency cryogenic sleep chamber.
When she woke up again, she was face to face with a red-haired boy.
His skin was pale, and the long red hair on his forehead covered half of his face. The only eye that was exposed was like an onion sliced in circles.
Later, Shenzhou discovered that the top hatch of his spacecraft was connected to the wardrobe in the red-haired boy's room.
Due to the turbulence of time and space, her spaceship was caught in the gap of time and space. Time came to a standstill, causing space to become turbulent. The hatch on the top of the spacecraft overlapped with the wardrobe door of an unknown planet.
With just one door separating you, you can travel between the two spaces.
In order to repair the spaceship, Yetu made an agreement with the boy named "Nagato" and joined an organization called "Akatsuki"...
PS:
1. Probably a short to medium-sized novel of no more than 200,000 words, cp Nagato.
2. The original timeline is a bit messy, so I've roughly summarized it. Age settings for this article: Nagato is four years older than Obito, two years older than Yahiko, and one year older than Konan.
3. Background setting: Nagato met Yahiko Konan when he was 6 years old. When he was 7 years old, he became a disciple of Jiraiya and studied for three years. When he was 11 years old, the three formed "Akatsuki". When he was 14 years old, the three battles began. The heroine and Nagato were both 12 years old when they first met.
