New version of the 1990-91 3-part Knack OVA *Korogashi Ryota* (*Rolling Ryota*). This borderline hentai show centers on Takao Ryota, former fearsome biker turned current fearsome bus driver. He's mostly focused on getting laid and beating up current biker-gang members, but sometimes he uses his fists and/or his bus to help a damsel in distress. Sometimes comic, sometimes ecchi, it gets increasingly sketchy. %20%5B73EE0332%5D_001_19275.png) %20%5B7C02984E%5D_001_7511.png) Although these screencaps are tame, there's plenty of NSFW content. There's even some censorship, mostly used for comic effect. New encode from the R2J ISOs. New translation and typesetting.
