[Vagina Dentata (Hirota Masatane)] Atama o Washawasha Suru Hon Soushuuhen | A Head Patting Manga Compilation (Girls und Panzer) [English] [GH] [Digital]
Our comments: So this is a compilation of some previous works as listed on Pg.004. I sadly do not have the last one, "A Duck Team Head Patting Manga" (アヒルさんチームが頭をわしゃわしゃする本 Ahiru chiimu ga atama wo washawasha suru hon), but if someone finds it and scans it, please feel free to share it. But as always, enjoy and support the creators when you can! It really helps!
