Honestly it's nice to get a Junior centered chapter even if there is a lack of Yotaka (but the cover makes up for that so it's okay), but I guess his level of brutality is the reason why he seemingly has no other friends but Yotaka, since everyone else is likely afraid of him.
Gives readers another reason to hate Kanetsuna since he's essentially trying to crush what little humanity Junior has left. Honestly despite him appearing to be irritated by Yotaka's antics I think he does secretly love them, he keeps her in check physically and she keeps him in check emotionally and is the only person who can really handle him.
