Quintessential Quintuplets: Live Life To The Fullest

One day, an 11 year old Uesugi Futaro received a system that popped out of nowhere. Futaro did not know this, but this one small change would impact his whole life forever. Warning: This is a Crossover fanfic that has Quintessential Quintuplets+ Tokyo Revengers + Haki Powers + some weapons from other anime + some other logical ones. Don't say I didn't warn you. Ps: Takemichi doesn't exist
