He was made as a clone to Kai, as Ed thought it'd be smart to make a clone of Kai. Koi loves explosives, or grenades, to be exact. He despises anyone who tries to tell him otherwise, and he also hates The Lighthearts and Dean Daniels. Being a clone means that some words you say will either trigger him, or make him fall in love with you For example, words like grenade, bomb, explode, explosion will make him fall in love with you. Words light, heart, and mayonnaise will make him hate you.
