Read the summery!
There's recently a manga about Nanao's cousin (Masato), you should be able to find it here
See the other mangas by the same author under the summery.
I already read them all. It goes up to volume 14 and I read that the series is still ongoing but couldn't find anything regarding volume 15. Thanks though you peeps.
Anyone know if the Warui series by Sakuraga Mei is still ongoing? I haven't read the manga for a couple of years after the 12th volume and was just wondering if it's still being serialized.
