In DxD with meta essence gacha (polish version)

This story is slightly inspired by "Meta essence gacha in marvel". I'm a beginner so please don't expect my novel to be as good as the inspiration.
The novel itself is in my native language, Polish, even though it is not a choice for a webnovel. I suggest using google translator, I am aware that Polish is difficult for foreigners.
I will not write about the plot except that the virus from tensei pandemic on steroids was added to the essence. (I'm not sure if that's a good idea. I recently read "Eiyuu Ou, Bu o Kiwameru Tame Tenseisu: Soshite, Sekai Saikyou no Minarai Kishi highlander" and wanted to do a "gender bender". Please express your opinion on this.)
Please remember I am writing only for fun
I hope readers will like the title.
I hope for constructive criticism.
