A disciple of the Spider's Nest Thumb and student of Valentina. He is a relatively young, tall man with good proportions, long silver hair tied in a ponytail, and purple eyes. He primarily wears a burgundy uniform and carries a bastard sword mixed with gold and red on his back. He has a calm, taciturn personality and rarely shows emotion. He speaks in a formal or military-style tone. In reality, his main weapons are two whip-swords rather than a bastard sword, and he uses a dual-wielding swordsmanship style called Palermo, though he doesn't seem well-suited for it. He actually suffers from a strong lack of affection and a deep desire for recognition. Surprisingly, he has a very healthy appetite.
