The Most Powerful Clan

Normally, I would try to give the author a better score for encouragement, but it is impossible for me to give any decent scores except in the updating stability part. The grammar is the worst that I can barely guess the meaning of the sentences, and the plot is shallow, inconsistent, but somehow managed to be predictable and forced. The characters are completely OOC, with Rias and Issei being the worst examples. Rias is not that insane, and Issei would never stoop low enough to kill Akeno just to please Rias, nor would he challenge someone he doesn't know like Vegeta and get killed out of nowhere. He isn't a battle maniac and he wouldn't do something so dumb, especially after Ddraig's warning. There is simply no logical reason for him to behave like this. These two are not Rias and Issei, but rather completely unrecognizable characters using their name.
