Uchiha Y/N is a 11 year old boy who witnessed his clan's massacre, along with his parents dead bodies and awakened his Sharingan in grief and rage, seeking for revenge, only to be sent by the orange masked man into a demon-filled Taishō-era Japan. Fighting for his life to survive in Demon world not until a Hashira forcefully brought him to Ubuyashiki Mansion. Initially defiant, he found in Ubuyashiki a fatherly figure who showed him purpose beyond vengeance. What would the young Uchiha do? Will he accept the fact he's already trapped in the place where he doesn't belong and embrace his new life as a Demon Slayer? Or will he do anything to find a way to get away from that nightmare and make sure to find and kill that orange masked man?

I ALSO DO NOT OWN UCHIHA AND THEIR POWER, IT BELONGS TO MASASHI KISHIMOTO, MATANA!!!

Y/N is an average person who just wants to focus on his job without any distractions, even though the money he earns from his current job isn't enough. So, he needs to find a suitable job that pays well. The only problem is, he doesn't know where he's going to live. Luckily, his mother suggests an apartment complex where she used to live. She tells him that it's affordable and offers shared rooms. She also mentions that she made friends while living there and hopes that Y/N can make friends too, since he hasn't had any friends since childhood. However, Y/N doesn't like the idea of sharing a room with others because he thinks it will only bring unnecessary problems. But he can't argue with his mother because he cares about her and wants to make her happy. So, he reluctantly accepts her suggestion for her sake. Once he moves into the apartment complex, he hopes to meet nice people and make friends easily. But unfortunately, it turns out to be a complete nightmare! Disclaimer!

Y/N Zenin, is regarded as a failure and a disappointment by his clan, the Zenin. Born into a prestigious family known for their powerful jutsu and mastery of chakra, he entered the world without any chakra-. This not only sets him apart from his clan but also subjects him to ridicule and disdain from his clan members, who take pride in their abilities. How will Y/n affect the Naruto story?
