_Midori no Neko_ is the first anime in Tezuka Osamu's "Lion Book" series of six OVAs. Viki provided the original translation; Orphan Fansubs did translation checking, timing, editing, styling, and QC; the raw is from onidragon. _Midori no Neko_ actually predates _Dallos_, but it's not clear that it was actually published on VHS. Thus, _Dallos_ is usually credited as the first OVA.
