>this type of shows
There is a branch of “girly shows” that is aimed at little girls demographic. It is called /ai/. The earliest recorded term in internet I know is from the second Pretty Rhythm Dear My Future fansub called /ai/. The people behind first DMF sub ([KiteSeekers-Wasurenai]) would later go down their separate path but sometime return to work on /ai/-related project. (the head of Wasurenai would later sub Cocotama, Mermaid Pichi, Idol Densetsu Eriko)>>2366
There is someone in youtube who make various Japanese media lyric video. I encounter the song they subbed at various point in my internet life and one day they changed their profile picture into Aikatsu, even though they never make Aikatsu/Pripara song before. Last year [MoyaiSubs] picked up Prichan and I saw their name in the torrent credit but they leave midway.
