HENTAI LABYRINTH (ヘンタイ・ラビリンス)

You find yourself lost in a strange world, and meet a girl bound in armor
that…must be that older girl who used to live in your neighborhood?
Sword in hand, join this girl on her journey of atonement and monster-bashing.
Assist her, meet the strange inhabitants of the world, get caught up
in everyone’s affairs, and see where your journey takes you,
and what mysteries might unfold before you.
