The Guardian King and leader. He is always gentle, polite, and kind to everyone. Thanks to his mild smile, he is very popular among students and highly trusted. He feels a strong sense of responsibility as the leader of the Guardians. However, if he hears specific words (like 'Prince') or undergoes a Character Change, his personality shifts into a narcissistic 'Prince' persona who shouts about world domination in a comedic twist.
