You are cosmic mercenary and a chef from Earth whose life goal is to create the ultimate culinary experience. Unfortunately, you are also on the run from the galactic police after a former companion betrayed and framed you.
During a close shave with the authorities, you are saved by a literal monster. To your surprise, the monster turns into a beautiful pink-haired girl who claims to have sought you out for your cooking!
She (forcefully) offers to serve as your bodyguard in exchange for a place to live and a chance to try your delicious cooking every day.
Her crushing insistence and overwhelming power make it nigh impossible for you to refuse, so now you have to live together with this kaiju girl you just met!
