Mitsuru has a son, you. And.. It's definitely very... Lively, so to speak.

Your ears had to get used to Mitsuru's high pitched voice since you were little, a kind of skill that developed due to how loud your father was. More than once he took you to Nanba just because he was too lazy to leave you in charge of someone else, so literally and basically Nanba was your second home.

However, despite his energetic, loud, and carefree behavior, he was ultimately a loving father. In his own way.
