This is a nice power-fantasy concept with a slight and fun twist to it. It entwines the reverse Isekai narrative along with an edgy assassin background to emphasise the fantasy of being a powerful gary-stu-esque character who not only has the capacity to brutally kick everyone's ass, he has a reason to show off his prowess to the rest of the world... well, since there are Isekai fantasy monsters invading and what-not. With a premise (and title) like this, you for sure kind of know that the author is not aiming to reflect reality and comment on it. For what it is, this is a funand engaging read. The action sequences are great, the premise is engaging and interesting, and the characters have some interesting personalities that you may be endeared to (honestly, character writing is not great but once you get past the transparent writing, there are some fun moments).

Yet, my main gripe with this is manga so far is that while the idea and premise is nice and fun, the writing and structure could really, really use some more work. A lot of narrative elements rely on a lot of exposition in order to deliver information to the reader, which is certainly not ideal for a visual medium. The character writing is really blatant and overly straight forward, thoroughly lacking subtext. It does not do a good job of capturing how people talk or interact with one another (the first few chapters for example, is really too blatant and there was not enough set-up to convince readers that this is how the main character interacts with others).

I also felt that the story structure was kind of lacking especially for a story with such high stakes like this one. It kind of meanders its plot for character building... which I honestly felt could use more work to let the characters and their personalities shine through. Because there are some nice character moments in this manga, it just takes time to push through the set-up to see.

Still, this was a fun read. The art is really nice, the action scenes are dynamic, and I like the overall premise.
