On April 12th, 2016, the eccentric and outgoing Rika Komachi opened up her restaurant, Ryokoma, alongside fellow chef, Masaru Ryono. Masaru is the complete opposite of Rika, however, that doesn't stop Rika from making romantic advances at him. Rika is determined to make Ryokoma the greatest restaurant ever and win Masaru's heart. However, Rika harbors a dark secret, a bloody past as an infamous assassin. Desperate to wash herself of that life, Rika now devotes herself primarily to cooking, however, just because she wishes to leave her past behind, doesn't mean her past will leave her.
