Ga-Rei Toka Mhp2G Toka No Hon. summary:

Another Ume doujinshi. Originally sold at the third COMIC1 in April of 2009, the series she's talking about are nostalgic by now. There's more MonHun, lots of Ga-Rei, with a crossover between the two as well. Who knew that was possible? There's also an original manga that, like Sae's growling stomach story, feels surprisingly real. It also has a little bit of Vocaloid (Rin & Len) along with the usual fun and silly stuff.
