I just think they're neat. Maybe "comfort characters" isn't the right term for all of them but they do bring me a lot of joy. Some are connected to kintypes in some way, others I just find very fun. This is actually a new list, so it's pretty bare bones and will probably be added to as stuff comes to me.

Probably connected to kinning Naoto, Kanji Tatsumi and Rise Kujikawa are big comfort characters for me.
