User blog comment:TheBlueSlug/Who should issei end up with?/@comment-60.53.101.242-20130930130606

Ahh the list of the impossible pairings. Asia, Akeno and Koneko are confirmed to always be together with Issei. For starters why Vali, that guy isn't interested in anything but fighting. Yuuto already has Tsubaki that is seriously in love with him. Gasper has a new vampire girl, forgot the name. Odin isn't even in the focus of the story. And Genshirou loves Sona and has 2 girls that love him too.

The biggest weakness you wrote is Rias would go on a rampage killing the girl who had sex with him and then punish Issei, the girl has already decide to comply with Issei's dream so she won't do what you said.
