"Tsugai" is a doujinshi focusing on Haruka (and her relationship with Michiru), in honor of her birthday. The meaning my Japanese-English dictionary gave for the word "tsugai" was "pair, couple" which fits well with the theme of the doujinshi. The artists are Hanako Obata and Hiyori Yamada. More scans from Tsugai can be found in the other two fanart sections. I'm not sure whether this is all one story or a bunch of shorter ones, so I'm just putting all of it on one page. I've only scanned about half the book so far, I should have the rest scanned someday.
