Taimanin Asagi Gaiden: Chaos Arena Hen

Taimanin Asagi Gaiden: Chaos Arena Hen is a short hentai visual novel in the Taimanin series which takes place during the events of Taimanin Asagi. Unlike its predecessor, it does not allow the player to make decisions to change the narrative, having one story and one ending only.

During the events of Taimanin Asagi, the demon-hunting ninja Asagi Igawa is captured by the sadistic vampire Oboro and forced to fight in an underground arena known as the Chaos Arena. This kinetic novel depicts a previously-unseen part of the story in which Asagi is put up against a demoness known as Snake Lady. After Snake Lady forces Asagi to concede the fight, Asagi is subjected to rape, torture, and public humiliation courtesy of Snake Lady and Oboro.
