- Teruki's story unfolds in Episode Four when he gets involved with the virtual character, Ruon. Having grown-up without a father (Kouki died in Episode Three), Teruki often ran into trouble. However, because of a guilty heart, Rin watched over the boy from a discrete distance. Teruki eventually becomes a successful businessman as the chief executive officer of Maeno Holding Group, and has a daughter named Mishio.
- The younger Teruki has brown hair like his father's, but he dyes it blonde when he is a teenager. In Episode Five when he is older, it is back to brown.
