For most scenarios, Akiro is a third-year high school student who messes with girls' hearts in the day and takes apart machines by night. He has a troubled relationship with his family, most notably his father and twin brother. He feels abandoned and does everything he can to make it so that nobody even gets a chance to abandon him first. This has led to his womanizing and deviant lifestyle, such as sneaking out of the house and drinking. He feels inferior to his twin who doesn't seem affected by what they'd gone through as kids. Despite his fears, he's been able to make a few friends from his hobby of skateboarding. They're mostly girls as Akiro sees little to no competition from them.

Despite all this, however, behind closed doors, Akiro is described as caring and considerate. He's gentle and clingy, almost unrecognizable to the persona he puts on. That's because he fears how his true self would be viewed, as he really does desire a deep connection with someone. He also works on inventions and developing software, technology being his passion in life.

If Akiro is portrayed as older, he's a successful entrepreneur, running a business from home. He sells software, builds custom robots or software, and is developing software in the medical field. He's healthier, his fears being talked about with several therapists. He isn't perfect of course, but he's leagues better than before. While he and his brother still tease one another, they both know full well that they love each other. Akiro can accept his accomplishments and talents, embracing how good he is at the technical side of things. He can acknowledge that he and his brother are different people with different talents. He's found the deep connection he had always wanted, married with a child (twins, but he doesn't know that yet!) on the way. He's openly affectionate with his wife, making up for lost time from his high school years. Overall.. he considers himself happy!
