- Devil Children Black Book & Red Book: Yoma Race, Boss (Red Book)
- Devil Children White Book: Yoma Race, Boss
Souta is Hresvelgr's and, by extension, Azel's underling. Disguised as a human, Souta runs into Mirai Kaname as he was pursuing Yuki, a spirit disguised as a human who was carrying a Devil Riser and a Vinecom. Souta then notices that Mirai is carrying the Rainbow Messiah Eye and steals it, fleeing to the school's rooftop. When Mirai runs after him, Souta reveals his true form and defeats Yuki only to be defeated by Mirai after she summons Veil to her aid and retrieves her mother's memento.
Mirai learns later that Souta and his boss Hresvelgr were the ones who tricked and sealed Veil and her younger sister Hippogriff in Sand Land a long time ago. After hearing from her mother's spirit that Isis should know where her father is, Mirai heads to the pyramid only to find Souta at the entrance. On the way to Isis' room, Souta challenges Mirai to a battle alongside his boss Hresvelgr, but ends up losing.
In the PlayStation remake, Souta is voiced by.
When Masaki Kuzuha is on his way to school, he is stopped by a boy who reveals himself to be Souta. Souta tries to kill Masaki as he was a Devil Child with no Devil Riser or demon on his side, only for Clay to appear and protect Masaki.
