Cold-blooded Master of Assassin. A young man with black-and-white hair wearing a long black coat. He hides small machine guns and knives within his coat. While Renya has little talent for magecraft, he possesses high-level skills in Karate, Judo, Aikido, Bajiquan, CQC, CQB, knife fighting, and assassination techniques. He is calm, collected, cold, and ruthless, with extensive combat experience. Lacking pride, he chooses any means necessary and knows when to retreat, but the one thing he cannot tolerate is civilian casualties; he does not want uninvolved people to shed tears. He orders his Servant, Assassin, to avoid combat as much as possible and focus on information gathering. He avoids fighting during the day and even takes casual walks then, hoping to form a temporary alliance with someone. In battle, he targets the Master rather than the Servant.

Renya's Servant. Class: Assassin. True Name: Hassan of Serenity. A petite girl with purple hair who usually wears a skull mask. Her personality is very quiet, reserved, and devoted. Since her entire body is essentially composed of poison, she can assassinate anyone she touches. She is also excellent at concealing her presence. Her Noble Phantasm is "Zabaniya: Delusional Poison Body." Because her body itself is poison, it is a technique to kill the target through close physical contact. She is absolutely loyal to her Master, Renya, and contributes to his victory, though she cannot exert her full power due to Renya's currently low magical energy supply.

Therefore, while he is willing to use it for his Master, Masayuki, he fights with his full strength using his bow in normal combat to avoid death.
