How about a Vibration Kekkei Genkai? It would be like the Barblanca of this world or one also made of rubber like Luffy, it would have a much better damage impact absorption.

Honestly it left a bad taste in my mouth that it did not prevent the events of 9/11 but I know that the MC is not omnipotent,still it would have been nice if it had at least tried and not been sidelined,I know that this event made the company have better status and influence,but I still feel that it was a bit empty and even forced on me that the MC did not at least try with something to prevent the casualties of 9/11.

At least for me I feel it would make the most sense for him to lock Venom/Flash in here, because if so I feel it adds that touch that the MC spotted Venom right at the right time and his suspicions although superstitious would make sense here because of the sudden way Venom/Flash came at them.

How the hell will you get into the vast world of DXD? How will the supernatural world fit in there? Considering that there were supernatural myths and legends there? Also, how the hell is he going to bring the Nazuverse into the mix? I don't know, the Nazuverse is already complicated, now with DXD in the mix it will only confuse the reader even more.

I don't understand why it makes Buu look like the biggest dog in the universe,it's true that Buu has quite tedious abilities in battle like his long durability to Moro's own magic or long term resistance,his god Ki is not really that gigantic in power it's just very big reserves nothing more,something like androids with their infinite energy but with limits.

Sadly this is true, unfortunately the author overloaded this work too much with unnecessary things, in fact he reached a point where he no longer respected the original material on which this fanfic is inspired, he eliminated 90% of the roster of the original Komi characters- san, just to add cliché things and not to mention modifying more hateful personalities (Hitomi for example)

there is not much to complain about, the writing, the description of the world and the descriptions of the characters are rewarding and very pleasant to watch, but sadly the development of the story is something that leaves a lot to be desired, the directionless introduction of Lumine , the limitations of the system to more than power, the massive overload of new characters (this includes a large amount of girls in the harem) the now hidden life of Hitohito in a renowned family on a possibly Multi Millionaire scale out of nowhere without warning from before and of course changes in Hitohito's personality making him extremely stupid, it is known that Hito is someone dense, but not as dense as he has been portrayed here, also the limitations of the system, why not add missions in exchange for really good improvements? load character cards or very good abilities and to finish with this review I feel that you have rushed many things in the development of the story that have simply overloaded it a lot and making it somewhat generic and with a lot of quantity than the quality that should be essential in the history, it would be good if you verified this, colleague, history is better than this and not get stuck in the same thing.
