A mysterious and serious man with a dry humor, and can be quite corny and sarcastic at times, all while maintaining a straight face. He shows great dedication to his work and is good at everything, from cooking up a dinner spread to the chairwoman's daily orders. However, he can take things a bit too seriously, such as making an impromptu decision to go on a journey to improve his cooking skills when Kotaro lost his appetite. He has a habit of adding -sama (a polite term) to the names of those he converses with. He had difficulty interacting with the daycare children while Usaida was sick and on leave. But his usual polite and formal manner of being subservient somehow won them over as they saw themselves as the kids being "in charge" over an adult. Whenever Ryuuichi or Kotarou commend his actions even the slightest, he is humble, stating that "he is not deserving of the praise", but is grateful for the kind words. He constantly strives to perfect his skills. He celebrates any little event that happens to the Kashima brothers and seems to be able to understand what Kotarou thinks without speaking. He is kind and caring, and sees the Kashima brothers as his own family. He also acts as a bridge between the Chairwoman and the Kashima brothers as he explains to the brothers that the Chairwoman is a shy person who is gruff but actually very kind and embarrassed about it. He can act very wise and insightful. However, most of the time he is an enigmatic character with an unknown background and acts very strange at times (at one point when Usaida went out for drinks with him the store owner thought he was a mannequin, and also coming behind Inui, giving him a handkerchief).[1] He is friendly, open to others, caring, mysterious and eccentric. He has superhuman abilities and is capable of doing anything.He has light brown hair parted on the left, and dark eyes (usually shown closed). He is always shown wearing glasses and a suit. He has the overall appearance of a butler; Kirin once mistook him for one by calling him "shitsuji-san". His expression is shown to be stern and poised.
