|Minoru as seen in anime|
Minoru Kokubunji (国分寺 稔 , Kokubunji Minoru) is a wealthy, twelve-year old genius, whose specialty is Persocoms. In particular, he has built a custom Persocom named Yuzuki, designed to look like his late sister, Kaede.
Minoru has installed personal data into Yuzuki such as dislikes, likes and personality traits that were once his late sister's. He has given her self-teaching software, meaning that she can learn things on her own instead of having to have programs loaded into her, as is the case with most persocoms.
For the most part, Minoru is a very reserved and soft-spoken individual who surrounds himself with Persocoms. His curiosity over Chi's origins leads to him becoming one of Hideki Motosuwa's closest friends.
Minoru does what he can to help his friends whether it be technological help, such as tracking things down or allowing Hideki to make video phone calls, or advice on relationships with Persocoms. Although he is known for being calm and collected most of the time, Minoru's attitude completely changes when Yuzuki is present. Similar to Hideki's behavior towards Chi, Minoru is very protective of Yuzuki and is prone to outbursts whenever she is in trouble. He is also very forgiving, always comforting her on the fact that it is never her fault if something goes wrong.
Minoru is also known as "M" on the Persocom bulletin boards, where he is considered one of the leading experts in the field of Persocom development. Minoru's late sister is Kaede Saito, a character from Angelic Layer.
- Minoru has four Persocoms dressed in skimpy outfits in the manga.
- Minoru modeled Yuzuki after his late sister, Kaede.
