thank you for taking my idea into account! really appreciated
will the story be centered on Freezing or DXD universe?

I just started the manga until chapter 225 and wow! OxO (I regret that the manga seems to be on hiatus or abandoned).

as I thought the cons are important: the invasion of the Novas forces humanity to unite in order to survive.
I can easily imagine Kouh being razed by the Novas! which turns everything upside down and makes a huge impact on Dxd! (yeah basically, no Issei, Rias,etc,...)

then how would the supernatural react if the Novas invaded Earth?
would they be able to defend themselves in the event of an attack? Would Sirzechs and others Dxd characters: Azazel, Gabriel, Michael,... be powerful enough to defeat a Nova?

the invasion causing an imbalance, would they reveal themselves to humans choosing to ally with them? how would humans react?

Would Kokabiel ally himself with the Novas or would he see them as a threat?

would the supernatural let Gengo Aoi experiment or try to kill him?

sorry for the avalanche of questions '

Love the story so far.

Add grafiya in the harem too please

Very nice story idea. I really love Freezing, so I am suuuuper excited for the next chapters! 3

the only thing this story made me is to want to see Kazuya as The Red Dragon Emperor, in order to "boosted" him a little! :p

joke aside, Kazuya's idea as Issei's successor is an idea that I like very much.

negative point, am I extremely skeptical about the world building between the two universes?
my knowledge of Freezing is fuzzy, but they don't match in my opinion. sending Ren into the world of Dxd or Issei into the world of Freezing would have been more credible.

Thanks for the awesome chapter.
