Intro video from last year's Jump Festa 2017, featuring Fukuda Yuichi (director/writer), Sato Jiro (Takechi-hentai) and Murotsuyoshi (Gengai). This extended version was available for a short time on WB's youtube channel. Might be of interest for anyone on the fence about the adaptation, or if you just wanna see Jiro and Muro banter for several minutes or so.
