Karato works as a secret agent for Daito, handling everything from corporate espionage to the occasional romantic errand—like delivering purple roses to Maya. He's known for staying calm under pressure, the type who keeps his cool no matter what's happening around him.
His past is heavy. His father once ran a company that collapsed, and in the aftermath, his family attempted suicide together. Only Karato and his father survived, though they both lost their identities in the process. It's the kind of trauma that shapes a person, but Karato somehow came out the other side functional, even if marked by it.
Masumi's father ended up being crucial to Karato's survival—he covered his school costs and eventually got him into the job at Daito. That kind of help doesn't get forgotten. Now Karato and Masumi are close friends, the kind where Karato genuinely just wants to see Masumi happy. He's someone Masumi confides in completely.
