They protect the final stratum of the game, the Lost Shinjuku. Sent by Visil, they have but one mission: to assassinate the player's guild, and keep the Labyrinth secrets from them, thus forcing the guild to fight the duo that helped and mentored them through their exploration. While Ren has great attack power, Tlachtga can weaken the party and cast several curses on them.
