Seiji's guardian and a genius scientist


A former scientist of the Star Cluster Alliance, Yapool was a genius and leading engineer in the alliance. Some of his technology also went into creating the Ultraman Suits. Along with the Minami family, Yapool was part of the inspection team sent by the Star Cluster Alliance, to see if Earth was ready for admittance. However, the team seemingly came across something that made them the targets of assassination by a high ranking member of the alliance. Yapool and the Minami family were on the plane that was seemingly destroyed by Bemular years before the start of the series. How he survived was unknown, but he did so with at least one member of the Minami family, Yuko's mother or older sister. Seiji was brought to him and he became his guardian supplying him with prosthetic limbs and an Ultraman Suit.

During his time on Earth, he made his living disguised as an old man running a small shop. He a has also gone out of his way to avoid being discovered.
