Cage of Eden, Volume 13

Yarai's finally made it inside the mysterious lighthouse by the sea, but like everything on the island, it's more than it seems, full of locked doors. At the top of the tower, a desiccated corpse, crouched in a barrel with a key under its tongue, will give Yarai answers he never bargained for... Meanwhile, Akira and Mariya are still trying to discover the secret to the spire, when two welldressed ruffians threaten to tear their group apart!
