Protagonist: Uchiha Haneda

Introduction: [Bonds + System + Uchiha + No Heroine]

After traveling through time and space and becoming a member of the Uchiha clan, you are born with a favorable impression system. As long as you max out your favorable impression, you can gain the other party's abilities.

Thus, an Uchiha who was born evil became the fifth Hokage due to many accidents.

Uchiha Obito: I want to create a world with Rin, Haneda, and Kakashi.

Uchiha Itachi: My capacity and everything I have shouldered are not even a bit less than Haneda's.

Uchiha Shisui: Only brother Haneda can inherit the fifth generation Hokage and completely change the Uchiha clan!

Senju Tobirama, Shimura Danzo: What?! The born evil Uchiha brat actually became the fifth Hokage!!!

(Note: The bond is mainly between Obito and Kakashi, with both sweet and sword)
