Konoha Hokage: Uchiha Izumi

[No system + healing + redemption + little girl reincarnation + trying to make up for the regrets of tragic characters as much as possible + early cautious development, later invincible monster]

In order to survive by lying low, Izumi Uchiha, who returned to Konoha, concealed her Uchiha identity and step by step became a proper direct descendant of the Hokage, making the name Sen Izumi famous at home and abroad.

In order to hold onto the obsession in her heart, Izumi, who had to ensure her own survival, gradually shed her cowardice and grew stronger and stronger, so strong that she even dared to stand against the entire ninja world.

For the sake of a stable life, Izumi devoted herself to building the strongest Konoha Hidden Village, planning and improving step by step. From her initial slight influence on the Nine-Tails attack, to guiding the Uchiha clan massacre event, to taking advantage of Orochimaru's Konoha Crush plan...

Until one day, standing on the opposite side of everyone, she looked at Kakashi who was no longer short on blue, at Uchiha Shisui who had regained his eyes, at Uchiha Itachi who had recovered his health, at the Konoha Sannin reunited once more, at Naruto, Sasuke, and Sakura who were absurdly stronger than in canon, and at the other rookies, and only then did she deeply realize that she had raised the difficulty of conquering the world all the way to hell mode.
