Suiu

The magic user of the Four Heavenly Kings, his specialty is wind magic.
He's smart, but he doesn't care about what he has to sacrifice as long as he completes his objective.
He's interested in Ryouga because of the unbalance of his looks and low rank at the host club and nominates him to be the new Demon King.
In order to keep an eye on him he becomes a host at 'MAOH', with his demonic charm he's actually the number one host.
