So... In raika's story he met Ritsu and Rei but what the fuck is this ??? Rei said that raika is descendants of harpy... ?? Hm?? Is this to follow up sakuma's vampire... Hm...?
Raika can't be counted as branch family but he is indeed distant relative of them
I'm sorry but it's crazy to me that parents can have kids and NOT be interested in what their interests are. Like you made that thing, it started developing it's own preferences and favourites and you're NOT interested in knowing what they are???
