User blog comment:B214/Light Novel Volume 16 spoilers/@comment-1884090-20131122135652

So This is my my first time posting on a blog I have read them before but have been two nervous to post so please be patient. The new main bad guy in this arc is quite serious he is number 1 a super devil and not that this is less important i consider them about equel he can also nullify sacred gear so that means issei would have to probably focus on his other abilities like Dragonification, devil abilities,Ascalon(which accels in slaying dragon but it still has all the abilities of a holy sword which are hurtfull to devils if i understand correctly) Dragon falmes,and he has a familiar that can evolve into who knows what, Akeno i believe will master her fallen angel mode and probably go beyond, Asia i would like if she got a balance breaker (for example something that turns healing into an offensive move like over healing someone she also needs to work on devil abilities so she does'nt rely to much on twighlight healing), From what i understand the Demon swords have a mind of their Own so Kiba would need to learn how use themwithout suffering the Consequences Koneko needs to learn howto control her new Form Kinda Like Akeno and her Fallen angel mode, Gasper should stenthen his vampiric powers and control his new powers Xenovia controlling the destruction abilities of Ex durandal and and the other abilities so she can maybe use more then one at a timle better sycronization, Roiseweiss still could probaly learn more about her trait of rook, Rias defeated Grendel which she finally is progressing more to my liking Grendel being an evil dragon and enhanced was probably stronger or about the same in strenth to Kokabiel so that shows her progress

Vali need to strenthen his devil abilties which he is the great grandson of the Lucifer and grandson of a super devil so it is very possible, Saji issue with not achieving balance breaker is myabe because he has four sacred gear an emotional state or the latter, We still Have yet to see the full capablities of Sona's new Rook Rugal or Knight Bennia,Sairaorg has room to progress and we still have yet to see anything From Seekvaira and her peerage.

In the end these are all my opinions so feel free to disagree or comment
