I'm looking for a comic called Exchange! vol. 1 is really easy to find, but it's up to 6 now and near impossible to locate vol. 2-5. Obviously not looking for pirated versions.
Matto Chimoto is the artist, and it's appeared in Bananamate magazine. There are other TG stories in there from what I found in my own search.
