*Minor Spoiler Warning* Going through the mountain of new isekai series coming out, this series has been a nice find. This series is one of your protagonist is overpowered as all hell but pretends to be weak kinda story and so far it's done very well. If you are a fan of seeing a main character underestimated just to show how incredible they are in a pinch then this is the series for you. Not gonna lie, they modeled the main character's appearance into stereotypical chuuni which the series itself is fully aware of and plays for comedic effect at times. He has the iconic eyepatchcovering a unique colorful eye with special powers, overwhelming dark powers and he's a vampire. I would not be surprised if later on in the series he gets white hair and something happens to one of his arms to become a fully equipped chuuni.

The main character himself has been pretty interesting as he isn’t a carbon copy of the everyman mold isekai protagonist used in isekais so the reader can easily self insert themselves into the story. You don't get flooded with the extreme perversion, overreactions and typical poor judgment calls which is honestly a breath of fresh air. He's an anti hero. He's extremely calm, rarely losing composure. He was summoned to a world to be dissected as a test subject yet barely bats an eye at the fact and took it all in stride. He’s able to amicably talk to a goddess on the first meeting. Has a good head on his shoulders being able to plan ahead and has a glib enough tongue to talk himself out of a troublesome situation.

The gimmick that makes this series “different” from your usual template isekai setting is that the main character was transported to a new fantasy world as soon as he was summoned to one before, gaining a new power and title each time, eventually settling for the current fantasy world he is in being mistake as an ordinary person caught up in a hero summoning. With each summoning giving him a new power, so he starts out with an overwhelming advantage compared to the residents of the fantasy world and other summoned people. Not really groundbreaking stuff here in terms of standing out among the crowd but this is just setup to establish that our main character is gonna be overpowered later on in the series.

It's still pretty early on in the manga and we haven't really gotten to the meat of the story or even established a goal for the main character to achieve but even without it seeing the main character adapt and settle in his new environment is pretty interesting to see.

Art is good which is always a good sign with isekai LN adaptations. The art done by an artist with an art style that I would best describe as conscious misproportioning. The proportions of characters sometimes feel slightly off, mainly in the face but not to a degree that looks bad, which makes the art style easily recognizable. Though sometimes this style doesn't work too well such as some of the cases for the animals drawn in the series. Aside from that the line work is great and the panel layout has been well done as well, as expected from an experienced mangaka.

I have read and reread this series multiple times even though there are barely any chapters out for it. There are plenty of moments in this manga that are just fun or satisfying to read such as the beginning few pages where he’s rapidly being transported to the different isekai worlds or the first time the princess confronts him for his unmotivated behavior and he ends up revealing a bit of his abilities. I have some high expectations for this series as the story has really started to pick up in the recent chapters as big events have finally been put into motion.
