Shiren 4 DS:Technique Library

Technique Librarian.

The Technique Library (Japanese: 技図書館, Waza Toshokan) is a service in  Mystery Dungeon: Shiren the Wanderer 4 - The Eye of God and the Devil's Navel. It allows players to store the Techniques that Shiren has learned. When techniques are deposited in the library once Shiren has learned them, they can be accessed later as needed. Once recorded in the library, they are never lost.
