Just so you guys know, the Owari no Seraph website is holding another character popularity vote for every single character. Like really, every single one (even Catastrophe manga original characters!)
It's all in Japanese but if you have a Twitter I think you can still vote (don't quote me on that one though lol). Edit: NVM, it's for sharing. Smh. Sorry for the misinformation.
Happy new news then I guess! I'm excited to see the results.
