I don't know why this ff didn't that much of reviews and very underrated, but here is mine:
This fanfic is good and maybe one of the best, why?? it's because the writing quality is good, not excellent or the best, but still good..... The characters are still the same as in the Canon, no Rias being so lazy, manipulative and dependent on his brother.... also no Chinese cliques, no befriending Issei and babysitting him, no hidden OP OC villain(i hate when there is), no pervert, idiot and simp mc.......
I can say that this is one of the best DXD fanfic that I've read, i know that there is more fanfic that is better than this and better grammar or story but I didn't enjoy some of those because of how much they change the characters, like Rias being too much lazy, manipulative, and dependent on her brother...... although i enjoy it at the start but too much of those types makes it boring and annoying...... no hate for Rias please, she didn't deserve it, although she manipulated Issei but she gave her virginity to him and become his wife, she also gave too much to him that it can't be measure..... what did she give?? she make him a devil, so she indirectly activated his sacred gear, because it won't be activated if Issei didn't gain power to control it.... Issei will also die when he was stabbed by Raynare... what Ddraig will save him??? no Ddraig won't, he would just got another host when Issei dies..... Rias also open new way and road for Issei, she makes him very powerful, Issei won't have it if he just stays as ordinary teenage boy.... because Issei became strong he also get girls, do you all think that Issei, a perverted, simp and beta teenage boy who also have a bad reputation will get many girls, beautiful girls and powerful girls??? they will just look at him with disdain or disinterest or won't even look at him if he just stay as ordinary...... Issei's life also became better, although his life became more dangerous but life with money, power, fame and girls is much better than nothing........ and let me say that without Rias, Issei will be nothing or just will die, although he have a Longinus, we can't be sure that other character will save him or train him, i mean they can just kill him and get his sacred gear right?? why would they waste their time and effort to train a perverted and idiot mc when they can just get his sacred gear and use it themselves..... think all of what i say guys....
