Protagonist gets reborn in DxD as a nobody, gets on the grindset and learns some unique magic.
Their motivation is to leave the universe ASAP, which.. is understandable, but in the end kinda makes less sense as they leave everyone they know behind, and at that point that includes powerful people like the satans.

Now, the first book is well-rounded gradual progression, paints a very rich world of magic and has an ok conclusion, deserved 4⭑

Completion and rating here are only for that first book.

Second book - we pretend that it does not exist, the protag gets pseudo-reborn in Naruto and it looks like it made her dumber - a classic thing with multi-book crossovers sadly, author wanted to “reset” the power level, and here it was done poorly (read - not at all, except she holds the idiot ball now).
And then she also started getting into politics of the country she got reborn in - for some reason??
And spent 5 whole years (timeskipped) participating in a brutal war for that country??
Why?
This seems super OOC, she actively avoided stuff like that in DxD, and was looking for peace?.

Yeah, so second book would get like 2⭑, and it’s also dormant because author lost steam too.
