Snake-Armed Girl

Fifteen years ago, Liane's America was shaken by a magical war between elves and Moon Demons that left many human cities in flames and many people turned into monsters. It's mostly calmer now - but Liane's high school friend is turned into a cat-monster under suspicious circumstances, and then Liane herself is turned into a snake-armed girl under even more suspicious circumstances. As she investigates, she uncovers terrible secrets behind the war - and is cursed to be transformed into a woeful shape if she reveals them. Can she save her country without sacrificing her humanity and personality?
