The villains in *Akuma Tou no Prince* made me think of another 1980s OVA that used neo-Nazis as the bad guys: 1988's *High School Agent*, released by M74 in 2015. VHS source, from ARR. See the blog for more information. This release is available for direct download from IRC bot Orphan|Arutha in channels #nibl or #news on irc.rizon.net.
