Kuzaku has black hair and dark brown eyes. He is around 190cm tall.
Kuzaku is often described as a big loyal dog due to how readily he follows Haruhiro and others.
He played basketball in his school because of his height. He lived with his (childish) older sister who was an employee for an unknown company. His father had a mistress that the family knew for a long while. After his mother passed away from cancer, he hated quietness as it reminded him the stays in the hospital.

- Saber: Once a ritual involving carving a hexagram into the blade and marking it with blood. Once completed a light magic spell that conveys Lumiaris's blessing on the blade to enhance the blade's sharpness. A side effect is that the blade glows bright enough to dazzle anyone who looks at it close by. Incantation is "O Light of Lumiaris. Bestow the light of protection on my blade."
- Bought a new shield and helmet.
- Bought a curved trapezoidal shield called a "Gushtat" and a pair of lightweight sturdy gauntlets.
- Ranta gave his Betrayer Mk. II to Kuzaku.
- Found a helm in the City of the Dead Ones that looked like a hawk's head. Since his current helm was fairly worn, he replaced it with the hawk one that Ranta named Hawk Helm. Kuzaku does not like the name.
- Picked up a large, solid katana and a large, heavy shield in the Mound of Katanas.
- Took a wide heavy dagger, found in a dwarf hole, as a backup weapon.
Kuzaku has deep respect for Haruhiro and often would unabashedly say that, creeping Haruhiro out. Being unable to focus for a long time himself, Kuzaku is thoroughly impressed with how Haruhiro is able to think about so many things in difficult situations.
Kuzaku fell in love with Mary and, even after being properly turned down in Volume 6, he is not completely over it.
After Ranta joined Forgan, Kuzaku found himself unable to forgive Ranta for that, since his treachery ended up with Mary captured.
