Some encouragement. Definetly worth the read. DxD and Testament of Sister New Devil are great materials for fanfictions, also helps that its not a GhostyZ fanfiction.

Poorly written and the characters are all one dimensional. The girls exist just to love writer's self insert. Made worse when said self insert isn't likeable at all

It is surprising how the different anime plots are built, since whenever I read a mixed one they always have gaps in their plots, but yours is perfect so far, I hope you finish it, I liked what you write.

Simply Perfect. as If the words I have read were alive, I felt like I was there, watching it not just "reading" it, No. It was much more complex than that. The plot is so flawless that I felt like that no one can surpass this book anymore, the character developments that can even make immortals shed a tear, the world backgrounds that have grand and mysterious feeling on it, you felt like there's something more in there. I cannot simply explain it by words. Stability of Updates? S P E E D. Writing Quality honed to perfection.

The author has serious writing chops and vast ambition, but this is very much a case of grand ambition causing the work to become bloated and unfocused. Or perhaps the focus is on bloated indulgence. Either case the story suffers from a fair bit of moralizing and navel gazing from an OP broken protagonist who tries his best to extract every possible ounce of forced tension he can in every possible scenario. Its a study in having your cake and eating it too from a writer with the skills to keep you interested in what would be a dumpster fire coming from 97% of the people on this earth.

Perfect!!! The worlds all mash together perfectly with the author filling out almost all of the gaping plot holes it is surprising how many worlds he managed to mash as well

I whould keep this simple and easy. There is a huge problem with pacing. Too many characters needs to be introtuced, too many girls needs attention, and too events happened in a small amount of time. When author asked what did you expect from mc, he wasn't in a world for even a week-yes, he wasn't. But maybe he should and that is a problem? 30 chapters we a not even in rizer arc. Shinmai maou in like 5 episods? So when you have so little time and so many characters all others problems comes in naturally. Why mc spending his points in useless stuff and wouldn't even train for a bit with his sword, or buy skills that whould help him improver himself? Especially when you lost so many internal monologues of how grave and serious situation he is? Because mc is not even one week in the world, making him op whould be boring. Even though getting op for toujo basara with boosted gear and skill creation - whould be easy-peasy. But oh well. Why all the changes are so close to original or lackluster? Because there is so many different stories that creating different dynamics are hard. Too many variables need to be adjusted. Why it's feels like old school rpg when all progres in side quests whould be nulled until main quest getting to the next point? Like saya talks about her feelings then just getting forgotten for 10 chapters straight. Same with different girls. Until main heroine wouldn't come they are on hold. You could skip whole chapters without any differences. What is power system, how different factions whould fair against each others? What whould elder brother of rias whould say about they unnoficial contract? Between mc and rias. Could he get in this mess with mc who have a lot of ties with different factions. Iseei was ideal, because he is just a human. Conclusion :the story like a pazzle. Author trying to make it work without knowing a whole picture.

I would normally drop a 4 star but I would feel bad to be the only one to break the perfect 5 star review, so here's a 5 star. It was a really good read anyways, I hope you post again soon
