Author here, I don't have any experience in writing and this is a Wish Fulfillment fic so don't expect anything grand. Enjoy it though.

let's be honest we just came here due to the title instant death and its literally what it is, Mc Is very op but that's what we came for. A OP mc that can give instant death as the titles specify which is true so if u came for something else then idk what to say but thus far its a enjoyable read and hope author doesn't drop it.

I am gonna write a more detailed review than my last one since I only said I just like it. Writing quality, it's has good grammar and everything barely any errors. That readers can usually spot. The only problem I have is of course you included characters from other anime which is fine, but me personally I would love if you focus more on the aspect of the DXD universe more. But I am fine with the MC learning other skills since he is basically death himself. Story Development is good, of course he is gonna be overpowered since he is the literal embodiment of death and there is a lot of funny scenes I love in this novel. Especially his cute obsession with Sona. The pacing is of course a problem in this novel but it can be fixed in the future. Something that I wish you could do is to expand his ability in the field of art a bit more and there are some plot holes in the University Visitation chapter, like what happened with his paintings or sculptures which needed to be somewhat explained. Other than that story development is good so far. Character design is good, its basically DXD and other animes that you could search with Google, I read novels mostly on my phone, so computer users will have a easier time to find the anime characters online. So far so good. Updating Stability is amazing, sometimes we get 1 to 3 chapters a day which is a lot. That is saying a lot also about author dedication and research to this novel. No pressure. World Background, is just DXD with other animes, but the main premise is DXD of course. So far a good novel that I look forward to reading in my day, and I hope you can continue. Hope you can take my review into consideration and that it helps you have to proceed with this novel.

Main premise of the fic is instantly sealed

Author-san, can I get like from my honest review? ... Sorry bro, the context of the story is good, but I don't know why, I always feel like I'm reading a NPC's interacting with NPC from the start of the story until the latest chapter now.😓 I mean the characters seems like they just doing their assigned program in the entire story.

Little advise for author; you cant just write [First time writing so don't expect anything, if you don't like it then just leave] when you post your work in a public forum and expect people who dont like your novel to just go away without without voicing their opinion. Since they invested their times, its only fair they get to voice their experience for other readers. PS; i havnt read the book, gave it 4 star so it wont affect the rating by much, but wanted to say my piece after reading author's synopsis.

Reveal spoiler

just wanna do this cause, Sona is best girl .

50 chapters, it's good enough, the story was great, one of the best romances involving sona and dxd, the mc was interesting. Yes he was super overpowered, but the story does not actually revolve around the first wishes, the mc grows into something more, something greater and it organically mixes with the lore of dxd, not changing it or destroying it, but making it into something greater, this review is from chapter 1 to chapter 50, because for me, the story died after chapter 51, it was a good ride, it was truly a great story. Rest in peace.
