I already watched Gargantia.
It's an anime I haven't seen yet.
Also you have to wait until the next episode impressions before you can guess again otherwise it doesn't count!
Have you really not seen cowboy bebop
my random guess is Nyan Koi! (because no one else will guess it... and why not) but if I get it right before the end I am totally gonna request you watch Sakamichi no Apollon
