Strong sense of responsibility. Highly capable among soldiers, leading to his promotion to Superior Private. Always makes appropriate judgments for the situation. Possesses keen, calm insight and a sharp intuition that notices anomalies quickly. Equipped with leadership skills to command a squad. Has the high qualities required of a soldier. His physical combat ability is also exceptional. He does not flinch even when facing many American soldiers. He is especially praised for his natural talent, being called a sharpshooter. On the other hand, he says it is only natural to want to return home alive. Cares for his comrades. At times, he shows a rebellious spirit, stating his opinions to superiors without backing down. Immediately after landing on Peleliu, he felt a sense of mission to fight as a Japanese soldier and believed he had no hesitation in killing American soldiers. However, after witnessing a dying American soldier on the actual battlefield muttering "Mama," he realized that the enemy is human just like the Japanese. (In this scene, he sometimes vomits from shock.) That voice never leaves his ears and changes his stance as a soldier. He is kind and cares for his friends. His family home is a rice farm in Ibaraki. His father died young from a chronic heart condition.

Sent to the war zone, he wishes to return to Japan alive and die on a futon in the end. He becomes an irreplaceable comrade-in-arms with Keisuke Yoshiki through their long and harsh life in hiding. He is not particularly sharp or efficient. Even in a tense war situation, he starts thinking about other things. A clumsy, ordinary person. Possesses a fine eye for observation and creativity due to being an artist. There are scenes where his sudden flashes of inspiration save his comrades and himself from danger. He dislikes unnecessary conflict between comrades. Instead of believing only in one side's right or wrong, he views the situation causing the conflict as the problem. He is thoughtful toward others. By the way, he has loved drawing since he was a child, so he never stops drawing whenever he has free time, even during combat. He dreams of becoming a manga artist in the future and making his experience on Peleliu into a work. Possesses the originality to create stories. His drawing skills are very high; he can draw almost anything he has seen once.
