Initially nervous and scared because of Kamoshida's abuse, once the tyrant of Shujin was neutralized, his excitable and loyal nature undoubtedly shines through. While his enthusiasm can become annoying, at times Mishima will still be hesitant and respectful, often apologizing for texting when he is sure the protagonist is busy. Mishima idolizes the protagonist as a cool superhero, most likely viewing the protagonist as his "savior" from his abuse under Kamoshida. There are times when Mishima will cling to the protagonist, once saying he will never forgive the protagonist if he is left behind. This clinginess and other socially awkward behaviors is likely due to his past of social isolation as a victim of bullying.
