if you didn't want to be a Rias Peerage, why did you choose kiba?! even when he was dying and in the process of devil reincarnation!. I like to wonder about the authors now, their choices are sometimes random and many are disappointing.
why do kiba if you hate rias so much frankly when a writer writes with personal biases showing it's not a good sign in the first few chaps you established a very cynical view of the main heroine.
Was there any meaningful purpose behind his aggression other than being an idiot? What has Rias done till now that you called her a spoiled princess since you just met her? Also antagonizing Sirzechs because of what? Why not just write an OC who has Sword Birth instead of Kiba?
The pieces of evil do not force those who were revived by her to obey a master who in this case is Rias, because if it were true in the original, Kiba would not have been able to attack the church when Rias clearly ordered him not to attack.
Interesting chapter, you did a great job building the tension and suspense.
Thank you for putting thought into the world and how the lore elements function in it.
Can't wait to read whats next.
fanfiction authors be like: I'm following canon information then filling plotholes with fanon... in reality every bit of background info is rewritten with fanon
