He is 187 cm tall, weighs 78 kg, was born on November 11th, and has blood type B. He is characterized by his finger snaps and his catchphrase, "Haha!" He claims all women are beauties. However, these traits are manifestations of his lifelong attitude of "never deceiving or compromising on one's own desires." Trained in monarchical studies, he possesses extremely high leadership qualities. While he boasts that he will eventually "have the whole world in his hands," the "world" he envisions is one that shines brighter as a result of everyone's success; thus, he is favorable toward others who demonstrate abilities exceeding his own. Since childhood, he spent his entire multi-million yen allowance on models like ships in bottles. He is a die-hard sailor who has been building and sailing real sailing ships since middle school. He has the special skill of grasping accurate temperature and humidity through his senses alone to perform high-precision weather forecasting. Furthermore, he is quick to notice when something feels off, often saying, "A sailor's intuition is never wrong."
