Human-Shaped, Rule-Breaking, Unstoppable

When Sophie Reed empties her every resource into a spirit summoning ritual, the universe sends her Leo Hayes,  a cheerful young man in catastrophically loud floral shorts. The crowd loses it. Lowest-grade Contract Spirit in history, they say. What nobody knows is that Leo carries the Menace System, a power that feeds on breaking rules, shattering expectations, and generally refusing to behave. The more absurd, the more impossible, the more wrong he is by every known standard,  the stronger he becomes. He slaps the original summoner clean out of the picture, casually evolves into the Divine-grade Contract Spirit World Heartthrob, and grins at a world full of rules he was apparently born to demolish.
