On pixiv there is a bunch of fanart and djs about them. Just type 狂聡 (kyosato)
COME TO PIXIV.. its a heaven for kyosato fans fr ive been swimming in my tears of happiness ever since i found them on the site
I will! Any u rec specifically?
I recommend reading every kyosato works from this artist https://www.pixiv.net/en/users/12679263
Honestly they have the best kyosato djs imo (very in character/not ooc at all, and not to mention their art is almost the same with wayama sensei so thats a huge bonus honestly)
Any doujin of them that ppl could reccomend?
