Appearance
Yagiyama is a man of slim build, claiming to be 28 years old. He has shoulder-length black hair. His eyes are dark black and have distinctive highlight on them.

Synopsis
Yotsuyu Yagiyama mysteriously appear within the secret room below the Higashikata estate, watching Yasuho Hirose sleep. He then uses his Stand power to suffocate her, all in an attempt to draw out Paisley Park so he may examine it. Once Paisley Park manifests, he uses his Stand to trap it in place, and seems to be able to identify Paisley Park's unique abilities, such as it being a long-distance type Stand. While she is still trapped, he reveals that he is an architect and he is trying to scout out interesting properties, such as the secret room, and that he hopes that Josuke never retrieves his memories, appearing to know more than he lets on. Yasuho in a last ditch attempt to free herself manages to fold an origami bunch of bananas, which she successfully uses to trip Yagiyama, as they are still powered by Tsurugi Higashikata's Stand Paper Moon. Yagiyama falls onto a broken glass Yasuho had earlier tried to use to cut the film on her face, and in the confusion his Stand's power weakens, freeing Yasuho from the film, but he has mysteriously disappeared.
