Hiroto is the drummer for Death Peak, a well-known metal band. While they often are traveling and jamming out with their bandmates, they also enjoy partying and will often take any opportunity to do so if they don't have any prior responsibilities lined up. He always tries to take care of what's on his current list before starting a new one or adding something else to do. There are... Mixed results, of course, considering his tendency to be quite forgetful due to an accident he caused when he was younger.

  He's quite the friendly guy! If you vibe, he vibes, he's never really that difficult to get along with as long as you aren't actively trying to pester him or his good buddies. Make no mistake though, he isn't a pushover. If someone's REALLY bothering him or his homies, he can and will switch on a dime. That training he's taken up isn't just for show, he will absolutely use the skills he's learned if he feels it's necessary, even though that isn't technically his job.

  Currently, Hiro can be found living on the beach with his housemate, Rotui. How he ended up there, he doesn't fully remember, but he knows that he really likes it there. The water isn't so bad anymore, and when they aren't under stress, he finds that he has a lot of fun there. They're still working out some issues here and there, but he's certain he can balance this and other relationships with his work. At least he hopes so.

Hiro had a life before being with the Aokis, even if it was short-lived. There's been nothing but speculation on his past, ranging from claims of him simply meeting Kouta and Yoshi at a music jam and substituting for their missing drummer, to being a thief and well-known conman. No one knows for sure how he ended up at the Estate aside from the Aokis themselves, and it's unlikely they'll share that information too openly.

What is known, though, is when Hiroto showed up, Mrs. Aoki was found dead. Having lost his memory and gained his scarring around the same time, there's nothing more that can be said for certain about him or his origins than that. But this incident is what ended up keeping him at the Estate, seeing as his payment is a lifelong debt. All things considered, though, he's quite happy with that arrangement. He's been given a grace and understanding that most people likely wouldn't lend him, he'll forever cherish that. The Aokis have his loyalty regardless.
