Looks like we are getting more OreImo a few years after the light novels and anime has ended. Now, Kirino Kousaka has her own twitter page, and the titular imouto posted that Ayase is getting her own novel spin-off!
The novel’s title is Ore no Imouto ga Konnani Kawaii Wake ga Nai Ayase if Jou. Now, Kirino did not state how many volumes the novels will have, though the title suggests it might be a two to three part series. The series will be based on Ayase’s route from the scenario of the Ayase route which author Tsukasa Fushimi wrote himself.
The spin-off novel is set for release on 10 August 2019, so Ayase fans rejoice!
