I really like how the story is progressing. Great job!

It's an interesting start, and I'm intrigued enough to want to see how things play out.

Your grammar is passable, most of your mistakes are just missing words, incorrect word use, or bad punctuation. But overall it isn't atrocious, I won't even read a story if the grammar is bad enough. And the grammatical errors you do make aren't very jarring, so they don't really interrupt the flow of the story too much.

Your characterizations do feel a tad heavy handed though, Xenovia comes across as being far too forced in my opinion, same goes for Rias but not as badly in her case.

I liked to see how you handle the pairing since it’s rare for someone to do a IsseixTsubaki one. I’m interested in seeing how you develop the plot and characters. Can’t wait for the next chapter!

Cool and fun thanks

Issei X Tsubaki eh...

i look forward on your next chapter and we see if its interesting to read

I’m not gonna lie I’m pleasantly surprised this is well made I’m looking forward to the next chapter
