Anime distributor FUNImation Entertainment has written a blog post explaining their decision to release "OniAi" as a subtitled title only.
The company wrote on their website that "OniAi" is being released as a sub only title to see if its a viable option for those titles that might not get a DVD release otherwise.
"In other words, we're looking into adding more releases, which is a good thing," the company wrote.
The company also wrote that the decision to try out some releases as sub only titles versus English dubbed and subbed titles will not men an end to the practice of releasing dubbed animes.
"You'll still get English dubs on the majority of our titles," they wrote.
FUNImation also said that, because of the lower cost of production, the title will have a lower price point than titles with subs and dubs included, but will include a DVD and Blu-Ray disc in the packaging.
"OniAi" tells the story of a girl who wants to take her sisterly affection for her brother to the next level, but finds she has three additional rivals for his attention.
