Quick Transmigration: This Host Is Not Right

Zero Zero Seven always thought that making it this far as a rogue System was already quite an achievement. It had copied all sorts of tricks from the legitimate Systems next door, even secretly copying some of their abilities. That was, until it bonded with its thirteenth Host Zero Zero Seven: Host, run! The person over there has a legitimate System! I'm a rogue one. I can't take them on! Then it watched its Host wave a hand and order the guards to arrest the person. The legitimate System and its Host, now locked in the dungeon: ??? What happened?! Weren't we supposed to be like a mouse meeting a cat, panicking and running away? Later, when they faced the Lord God's elite agents, Zero Zero Seven nearly crashed. It kept crying and begging its Host to leave the plane and run for it. Then it watched its Host raise an eyebrow and tie them up in no time. The Lord God's trusted agents, now wiped out: ??? What happened?! Weren't we told this was some nobody with no backing and no power? Zero Zero Seven: You're not right in the head!!! [The male lead is one person in different incarnations.
