Isamu first appeared in the second half of episode 3, and in episodes 5, 5.5, 6, 7, 8, 9, and 10. He should appear in more episodes going forward, Isamu is a dog Henge

His age is listed as child but any voice that can manage to sound youthful will be accepted as an audition

Isamu is a particularly energetic and fun-loving boy, He usually gets carried away and tends not to think things through fully. He means well but he's clumsy and always quick to apologize and try to make up for the stuff he does wrong. He's extremely naive and instantly believes pretty much anything someone tells him, even if he knows something for absolute certain with proof he's a bit vulnerable to being persuaded he was wrong. He's generally fond of everyone, absolutely everyone but has one family member he values above all
