>>2689305kiddiebeats have a weird and awful sense of humour with various reasons to call her dad.
Underaged viewers with legit parental abandonment issues.
Takamori schizos who consider that Mori cannot be intimate with deadbeats since she's apparently Kiara's wife, and deadbeats and KFP are their children. These people also propagate stuff like Gura being their daughter, Clara is the child of takamori, etc, paying no mind that Mori doesn't talk about the ship at all in her own streams and Kiara telling chat to shut up when they keep bringing up Mori in chat. They're pretty much completely obsessed about it
Downright sexists with double standards. Mori going fishing is considered something only a dad would do while Ina and Reine's fishing streams is considered cute and comfy. Also recently forcing the idea that since Mori has golfed and has made barbecue she should just admit being 'our dad' when none of these activities are strictly male and them just going through mental hoops to force her into that character.
Most of the time it's a combination of either.
