They’ve been doing this for a while now. Pretty nice video and wallpapers inside. I don’t even follow Love Live (beyond the very first one), but I like their version of the heroines.
Pen name Ichiri. Various books and tapestries. The tapestry seems a bit interesting but I’ll probably pass. And as for the book I’ll be waiting for digital version.
Tsunako doing some doujinshi thingy for next Comitia. The book is available at Melonbooks.
May or may not buy it sometime later.
