Japanese title: がんばれ!(泣)こがさちゃん!!総集編：下巻
Space: Te-43a Circle: Lunatic Reform School
The conclusion of the series, the 120-page "Farewell, Kogasa-san", plus an all-new manga drawn for the occasion! (※You can start from Vol. 2/2 as well.)
I ended up with a lot of pages of newly done stuff, so I'm releasing them. (The printed version includes even more additional pages.)
