Ultraman: The King Got Picked Up by an Ultra Again

(No heroine) The whole universe is abuzz with the news: The undefeated king of the universe’s assassin world has arrived. The King has never lost. The King trounces the Four Ultras. The King is a Kamisama, the very embodiment of “battle.” Until one alien sees him with their own eyes... The King, who can blow up a planet with a single normal attack, is crouched in a high school classroom on Earth, tearing at his hair over a math test. Chaos Tiel, born from a singularity of chaotic battle intent before the Big Bang. Now going by Kurosaki Kuse, he’s a sixteen-year-old high school senior who skipped a grade and dreams of becoming a traditional Chinese medicine practitioner. He takes on jobs of all kinds from across the universe: Currently charging five million to beat up Belial, eight million to tie Tregear up and haul him back to the Land of Light, and ten million to help Earth fight monsters. No credit. Pay first, then the beating. Homework-writing services not included (underlined and in bold). Later, the whole universe is on the verge of losing its mind. Belial, clutching his lower back, curses: “He charged me five million to beat me up, then turned around and took ten million from the Land of Light to send me to prison!” Tregear, hiding out in the Science Technology Bureau, holds up an IOU with a blank expression. “Greenhouse-grown kids are useless. I challenged him to a fight, and he made me write three English tests to pay off my debt!” Zero leans against the wall outside a classroom at a top high school, questioning his entire life: “My master is the King of Combat, and his master is... a homeroom teacher for high school seniors?”
