Honestly though, much prefer Bell-kun the lovable baka over Kirito. They're similar in the kinds of characters they are (overpowered, chic magnet etc.) but they're very different as far as their personality goes. I find this guy lovable while I was, more or less, indifferent towards Kirito. :p
As far as Aiz Wallenstein is concerned...well, I'm kinda miffed at the fact that she doesn't show up in the finale at all. We don't see her apart from one moment of screen-time. Although her showing up wouldn't make sense since she headed to the upper floors before Beru-kun's team did, I still wouldn't have minded seeing a bit more of her in the final episode.
I'll be honest, I'll miss Hestia and her ribbon lol. She was a very cute kami-sama.
Overall, it was a pretty damn entertaining ride. The animation was pretty good where it counted (the fights were pretty damn great), I like the art style and sound was fitting if somewhat generic. The last revelation dropped at us in the final few moments of the finale made it very clear as to what kind of story this is - a hero's tale - the beginnings of a new legend. Which kinda makes the stu levels of Bell a little easier to digest, but yeah, I look forward to more content from this series. Sadly, I hear that 5 out of 8 currently volumes have been adapted. Meaning that it'll take a decent amount of time before we see any more of this series. Also, dropping that kind of a revelation at the very END makes it a cliffhanger of sorts. I am more curious about what happens next than ever before x(
Yes, I'm implying that it'll get another season. And why not? The series has been super popular in japan as far as I'm aware. Gotta be a sure-shot win as far as the chances of another season is concerned.
