>>3288596It's all good, it's just that Touhou has been a giant thing for a over good decade now, so I was curious how anyone poking around here could miss it. Your in for a treat though, it's doujinshi community is massive with tons of high quality art music manga and games, never minding the original series and official material. It's been slowing down lately, competing with the likes of Kancolle and Girls Frontline, but still lots of great material coming and in the backlog.
Your OP pic is Cirno (ice fairy) and Suwako (Frog Goddess) if you want to look them up.
