Naruto: Asura Chose Me, Naruto, to Defect and I to Defend the Village.

[No system, single female protagonist, daily development in the early stage, random killing in the later stage] Traveling through Konoha, there is no blood line limit, no prominent family background, he is still an orphan in an orphanage, and he has an inexplicable amount of Asura's chakra in his body. Yuu Sakugi just wants to study medicine in a low profile so that Naruto can save the world. As soon as the medical ninjutsu came into play, okay! Couldn't save Shisui. "My eyes are entrusted to you." "... Can I refuse?"
