Tsubura Hidetomo

The story focuses on four people from our world (High school students Makoto Mizuhara, Katsuhiko Jinnai and Nanami Jinnai, and History teacher Masamichi Fujisawa) who are mysteriously transported to the fantastical world of El-Hazard, which is threatened with a massive war between the human nations on one side and the insectoid Bugrom tribe on the other.

While retaining the game's setting, it is a bold adaptation, with the protagonist being Serina, who was the "imprisoned princess" in the game.
