- In addition to being "hot-headed" in his voice roles, Seki is a gunpla (Gundam figure playing) fanatic early on since childhood that he's often cast in mecha anime shows, including Gundam.
- Despite that, Seki can be very versatile, refusing to be pigeonholed by performing very different roles, even as a villain.
- Apart from voice acting, Seki is also a chairman of a stage troupe company, thus also spending time at theatre.
