Wednesday's issue of Weekly Shounen Sunday is announcing multiple new OVA adaptations.

Joujuu Senjin!! Mushibugyou, previously adapted to a TV series in Spring 2013, will receive multiple OVAs. The first special-edition DVD will be bundled with the manga's 15th volume, to be released on July 18th.

Nozo x Kimi, a spin-off series of Nozoki Ana, will also get an OVA adaptation. Nozoki Ana previously bundled an OVA adaptation with its final volume in February 2013. Weekly Shounen Sunday will also be announcing that Nozo x Kimi will be switching from Shounen Sunday Super's monthly schedule to its weekly serialization in the 26th issue.


Update
Fantasista Stella (sequel to Fantasista), Ane Log: Moyako Nee-san no Tomaranai Monologue, and Imawa no Kuni no Alice will also receive OVAs. Ane Log was adapted to drama CDs which also contained six flash anime shorts, while Imawa no Kuni no Alice had an anime CM last year.
