Serara, a young female member of the guild "Crescent Moon Alliance", is trapped by mysterious men in the northern city of Susukino and needs help.  Shiroe and his friends travel to reach her.  Annoyed by the game's tasteless food, they travel northwards, and go inside "the depths of Palm", a crumbling series of old mining tunnels.  There they meet creepy monsters...
But when cornered, they're dangerous.
Doch wie sagt man: „Eine in die Enge
getriebene Ratte beißt auch Katzen.“
Pero son peligrosos si están arrinconados.
Mais si jamais
on se retrouve coincés
Ma se messi all'angolo, diventano pericolosi.
Mas eles são perigosos quando acuados.
Впрочем… загнанная в угол крыса опасна.
