Wein Arbalest - ウェイン・サレマ・アルバレスト

Wein is the crown prince of Natra. He will take over the future of the country on behalf of his sick father. Although the retainers trust him due do his superior position, he is actually lazy. He wants to sell the deadlocked kingdom of Natra and lead a comfortable retired life. (Source: Official Site, translated)
