Please Someone Uninstall my System

A guy from our world dies. Tragic? Sure. Unusual? Not really. What is unusual is where he wakes up next. Reborn as Uchiha Itsuki, the son of a respected clan elder during the era of Minato Namikaze, things actually look… decent. Strong bloodline, political standing to get jutsu's and mentor, and most importantly, time. The Uchiha clan hasn’t yet walked itself toward its massacre. So yes, the future is a ticking bomb. But at least he has time to prepare. And a cheat. A summoning system. Which sounds amazing. On paper. A system that lets him summon a person and an item from other worlds. Heroes, villains, geniuses, warriors. Knowledge, tools, artifacts from different universes. Skills beyond imagination. The kind of ability that should guarantee survival in a world like Naruto. And is first summon is a kage level Gyarados. But what makes a summoning system truly broken. Not the summons themselves. Not the rare artifacts. Not even the possibility of otherworldly knowledge. It’s control function or slavery function to be blunt. No matter who you summon, hero or villain, saint or psychopath, they obey. They become loyal tools. That’s the rule. That’s the expectation. That’s the part Itsuki’s system forgot to include. Every summon arrives with their own mind, their own goals… and absolutely no reason to listen to him. A hero might mess up. A villain might kill him. An idiot might ruin everything by accident. And the worst part? He doesn’t get to choose, can't stop the system to not summon. Every year on his birthday system gives him a birthday bomb. Now, stuck in a clan destined for annihilation, armed with a system that creates more problems than it solves, Itsuki must find a way to survive a future he knows is coming… While dealing with the disasters he keeps summoning into existence. Which includes the Hyperbeam the Gyarados is charging. Power? Questionable. Allies? Unreliable. Sanity? Rapidly deteriorating. If this is supposed to be a cheat, someone seriously messed up.
