The Higanjima franchise includes three manga series, two live-action films, and two live-action drama series.
The 12-episode Higanjima X anime premiered in October 2016, and ended last March.
Multimedia studio Tetra announced via a YouTube video on Thursday that Higanjima X, its short anime adaptation of Kōji Matsumoto’s vampire manga franchise Higanjima (Nirvana Island), will get a “special chapter.”
As with the previous anime shorts, the new anime will debut online, and will again feature one voice cast member playing all the characters in an episode.
