Traveling to Shisui, I Change the World of Ninjas

I will reshape Shisui so that he has a modern mindset, is self-interested and decisive in killing, and has a bottom line to not kill innocent people indiscriminately. Kill Danzo and stay alive to contain the higher-ups, and use each other with Sarutobi Hiruzen. In terms of his relationship with Itachi, he pulled Itachi out of tragedy and became the leader of Uchiha together.
