This is a beautiful and wonderful piece of art. Truly the handsome and brilliant Cho-Marisa's charm cannot be denied. Hoping hard that the fourth one gets translated soon, it's nice to see two of them show up on this site.
Seriously, if you've never tried to play Cho-Aniki at least once, then you're missing out on life. And you're also missing a lot of the joke to this doujin.
