Asagi Igawa (井河 アサギ) is the main protagonist of the Taimanin Asagi visual novel series and the OVA series. She remains one of the key figures within the Taimanin setting, even in other spin-offs.
Igawa Asagi is a veteran Shinobi. After defeating her archenemy a long time ago, she thought she could finally settle down. Yet, her archenemy was revived from death through a pact made with the head demon in the city and swearing to take revenge on her by hurting those who are close to her.
Asagi, her boyfriend, and her sister Sakura (also a ninja) are some of the targets—they are captured and subjected to extreme emotional and sexual abuse.
Taimanin Asagi, or Anti-Demon Ninja Asagi, is the first entry of Taimanin games by Black Lilith. In the past, humans and demons have made a pact to never meet or cooperate with another.
After the release of Taimanin Asagi Battle Arena, more and more games were released in English and gained official translations, like Action Taimanin on Steam. While some of its content is eroge or ecchi, newer releases have been more SFW.
