His family has served the Hanamiru house since his grandfather's generation, and he has lived in the same household since childhood. He excels in programming and possesses world-class hacking abilities. More than just being a science-minded person, this is the result of his own research to be a worthy Recorder for Koshiro. Despite this, he claims that staying by his side as a Recorder is merely an 'inseparable bond.'
