This is an RPG with an overly simplified combat system and very, very slowly scrolling text. An interesting feature is that you can draw (or modify) the main character's face from scratch with an in-game paint program. You used to be able to find a walk-through (in japanese) as well as a lot of the CG at Retro PC98, but the link is dead now. The adult content is various girls missing some clothing you encounter during your quest.
