Izuka is also a mad scientist; he created the elixir that turns laguz into Feral Ones. At one point, he tries to feed a sample of the elixir to Muarim, who was saved by Rafiel shortly before the transformation finished. Izuka wields the most powerful dark tome in the game, Balberith. He is the boss of Chapter 4-5 in Radiant Dawn. He drops Balberith when defeated, but he can summon four enemy laguz per turn and uses the Rewarp staff to avoid enemy units, making defeating him difficult.
