That is a page of reviews at amazon.jp. I saw this there:
6月発売予定の13巻も限定版あり(OAD付属)とのことで、アニメ2期にも期待が高まります.
Software translation:
As many as 13 volumes of June sale schedule there is a limited edition and (OAD attachment) with with thing, expectation increases even in animation 2 period.
That probably means with volume 13 on June there will be an OVA and there is hope for an anime season 2.
About the OVA:
