Daikichi is a 30 year old bachelor who has a tendency of scaring away both women and children. Whilst he doesn't exactly mind that he scares children, as he isn't too fond of young people, he seems to be lonely as a single man. At his grandfather's funeral, he meets a newly orphaned illegitimate child, named Rin. In a fit of anger at his relatives' cold shoulder to the girl, he announces that he will be the one to take care of her. Daikichi now finds himself in the role of father, and must adjust his life accordingly. Daikichi doesn't have much motivation aside from getting to work each day. When his grandfather passes away, Daikichi feels sorry for the unwanted child that is left behind and takes her in. A bachelor and inexperienced with kids, he has a lot to learn so he can care for Rin properly but with his laid back personality and honest hard work to give her exactly what she needs, Daikichi learns as he goes. His patient, awkward, gentle and straight forward nature works perfectly opposite to Rin's shy wit. He is constantly learning as a new parent but you can't help but love him for each mistake he makes.
Daikichi's cousin on his mother's side and Reina's mother.
Rin's childhood friend, who is in love with her.
When Brandon Heat was first taken into the Millennion group by Randy, Widge Burns was the person that had given Brandon a place to stay and work at, allowing the young man to stay at his office while Brandon's friend Harry McDowell learned the business end of Millennion. Widge made his living by being a collector for the various bookmaking schemes Millennion ran. Originally, he had his best friend Gary do some of the enforcing of the debts that were made, but he had Brandon help Gary out. Widge, like Big Daddy, is almost as old as Millennion itself, and knows the history of how the organization was founded by Big Daddy. Although he doesn't like getting his hands dirty, he is often known to kill those who betray the Code of Iron, Millennion's basic law. But as Brandon's lot in Millennion improved, mostly from Brandon's constant contact with Big Daddy, both Widge and Gary profited with improved positions within the organization. And when Widge's elderly mother eventually grew ill and died, it was Brandon's influence that allowed Widge to place her in a decent hospital, where she could die with dignity; however, after Brandon's death, Widge's fortunes, along with Gary's, took a downturn, the two of them becoming downsized and unemployed. Widge eventually lost his sight due to glaucoma. But when Brandon, now as Beyond the Grave, had guarded Mika Asagi, Big Daddy and Maria's daughter, he took her to Widge's home. Gary, who was living with Widge and caring for him at the time, didn't recognize Grave at first, but Widge recognized the voice of Brandon, and taken the two in. When Grave left Mika alone with the two to find Dr. Tokioka, Widge then told the story of Millennion's founding to Mika, like he did with Brandon years before. Sadly, though, Widge, along with Gary, were killed by Balladbird Lee, who also captured Mika to force a battle with Grave.
