I'm a Cheater and She's What?!?! (Haru-Haru Glitch System)

God Anus, Ruler of the Uranus Planet, unbeknownst to most, high above in the celestial realms, 

He gets bored and decides to make a system called "Uranium System.".

He implemented a radical experiment to grant the inhabitants of Venus, Earth, Mars, Jupiter, and Saturn the chance to alter their fates by engaging in battles against the monsters spawned by God Anus himself.

But Haru-Haru, our ML, is a dumb and scared ass kid and can't get any significance in his fate after the system started.
