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.

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. See this blog entry for more details.
