[Tokyo Revengers] Would a Reincarnated Sword Cultivator Dream of Delinquents?

This story has been abandoned. Second-person reader-insert, with a female protagonist. She has no name, as Heaven has erased it. All-pairings. There is both familial and romantic love. Canon pairings remain intact. There will be some yuri-flavored gratitude cuddles. A handsome, black-haired sword cultivator who wears his hair tied up, a genius at swordsmanship. After being persecuted by his sect, he dies alongside his pursuers. Although she is covered in blood and looks very strange, she is sent to the hospital by Shiba Yuzuha, who has no choice but to take her there after hearing her call out "big sister" while half-asleep. Simply put, this is a story about a sword cultivator with an extremely high combat ability, who has basic common sense implanted by Heaven, tries to repay a debt of gratitude, and infiltrates a group of delinquents. Everyone survives. The timeline has been changed. Theme: People should learn to be grateful.
