Intelligence: Kuzuki is highly skilled and trained in martial arts, and can expertly use his knowledge to catch even a Servant like Saber by surprise and nearly kill her. He is very observant and intelligent, allowing him to quickly identify Shirou and Rin's plans, but he generally just follows Caster's plans.
Weaknesses: Kuzuki's fighting style is only effective the first time it is used against the same opponent due to how unusual it is, making it unsuited for protracted battles. Kuzuki is weaker without Caster's reinforcement magic.
Notable Attacks / Techniques:
Snake: The martial art that is the basis of Kuzuki's style. Having mastered it years before he was expected to, he keeps up his training every day, keeping it perfect over twenty years. It focuses around striking vulnerable points on an opponent's body, such as their forehead, throat, heart, and spine, and he has a policy of always aiming for death blows. He keeps his arms flexible, like whips, quickly moving from unexpected angles and directions to catch an opponent off guard. It exploits this confusion, so it becomes less and less useful the more an opponent is exposed to it, becoming useless against Saber after he uses it just once.
Key: Base | Reinforced by Caster
