When I look at the Walkthrough PDF, I see a "Raijuu" in the Monstergirls List as well as in the Monstergirls 2 CG Room, but I can't seem to find any info on  where to find them, just that they're "A monstergirl which can be found in many dungeons.". Anyone know where?

Some of monster not listen yet from i was told from list 1 monster from begus dungeon and central dungeon just look for monster 2nd list from dorgania dungeon. Well if still have trouble walkthrough guide has list of monster city or dungeon location for monster

You can find Raijuu in the El Arma Gravesite, just roaming the town like the cowgirls in Sivireta.
