What a great pilot and premise. Very enthralling story when it even still kinda feels taken from bits and pieces from other series. Reminds me of the feeling of Redo Of Healer or dark themed series, mixed with isekai, and has our MC locked in a tournament with really great outcomes and very bad consequences where both have either a light but still kinky reward or has a dark punishment you can’t escape. The MCs perspective as a gamer and Kouji is as a person is basically a badass on a mission.

The art is very unique and has a great flair to it. It is more of a sketchy felt pen look but with a lot of precision and lines for shading. Usually I think styles like these can get messy and too complicated but this really is great and brings out the exaggerated emotions, poses, and body’s/body parts. In other words very great imo. The nudity is hard to explain sort of. It has the exaggerated body parts and doesn’t go full nude yet in the chapters, but got dayum are these drawing insane. For example the one who summons our MC has huge breasts in very scantly covered not leaving much to imagination, reminds me of Dragons Crown now that I think about it, like the sorceress but even more 🤤The chapters ending and beginnings have a nude scene on them instead of blank which really helps the lewd levels I crave while still not going overboard.

Super excited for next volume.

I have to admit that this is pretty interesting so far. The consequences of losing is pretty intense but what is the end game for it? Are they bred to have kids or just bred for weird fetish satisfaction at the highest level. Hopefully we get a fuller view later on. The next foes he will have to face will be a varied lot and a wide spectrum of character types, so good times next volume. I must say also I think I like Zule the best she is pretty cute and has a brain. Good thing I picked this up, I initially was going to pass on it.

Boy in high school is transported to a world where you fight anatomically exaggerated women in reveling clothing...he fights them in an arena...if he wins they become part of his 'harem'...this is a fantasy that is very much geared towards adolescent boys; VERY strong sexual imagery - very misogynistic undercurrent.

Interesting premise and amusing, could develop into a fun series. I am curious to see how it goes and develops beyond the gladiatorial aspects. This could turn into something good or diminshed returns.

Gooner trash

Not really interesting. Its just soft core porn for people who have a sadistic streak. Art is pretty good i guess.
