Wow, this series turned to shit.
Seaweed should've won in the first.
The original mango was an entertaining raunchy comedy. The +imouto sequel is not even a comedy anymore, just creepy people playing fucked up sexual games.
Seaweed won't win, but Shiho (library girl) might. In the earlier chapters, when she showed up, Gorou and Aneki started maturing, so basically she's like the gateway to Gorou's moving on.
Thank you. I love these two. I really hope we get up to speed with the translating.
