Ryuu Ishigoori

Ryu is the hot-shot cool guy type that guys admire and girls adore. He enjoys a good fight and good women, which he had both of in his previous life. Despite not having any real regrets, Ryu compares his old life to being a "moderate eater". A vague thirst has been looming over him, leaving Ryu still unsatisfied because he's never had any "dessert" in his existence. He wants to use his chance at a second life to find an opponent worthy of satisfying his insatiable hunger because he's never felt full before.
