2.5次元の誘惑 [2.5 Jigen no Yūwaku] #9
2.5 Dimensional Seduction Vol. 9
A hot-blooded romantic cosplay comedy begins when an otaku meets a girl who dresses up as his favorite manga character. This sexy manga series comes recommended by Eiichiro Oda (creator of One Piece )–and don’t miss the anime, coming soon!
“I have no interest in real girls!” So claims Okumura, the president of the school’s manga club. He’s your typical otaku, obsessed with a sexy (fictional) 2D manga character known as Liliel. Then the new school year starts, and a (real!) 3D girl named Lilysa whose passion is cosplay joins the club. Lilysa convinces Okumura to become her photographer–and guess who her favorite manga character is? Not only that, but Lilysa is into modeling the fetishy stuff! The boundaries between 2D and 3D start to blur as this hot-blooded romantic comedy unfolds.

Life’s a beach and then you make that joke for the 80th time. This entire volume is Okumura and the girls working on a bikini-filled cosrom that promises lots of skin and awkwardness. But, when your series does nothing but show skin, what can your beach escapades possibly offer?
Sometimes, you get surprised. This manga has, for several volumes, remembered to be about something other than freestanding breasts and done it quite well, but I have to admit that I expected to absolutely not get along with its foray into the beach episode.
Except, in a move that I don’t suspect was entirely deliberate but was still damned clever, it certainly has its cheesecake galore, but it really zeroes in on Okumura’s rejection of 3D girls and his relationship with all of them amidst the sand and surf.
Oh, and it also takes a look at their teacher’s exploration of her lesbian relationship. And it finally has Mikari and Lilysa take about what Okumura means to them. Then it also manages to be incredibly funny to boot.
Where to begin? I love that Okumura actually had a reason for rejecting any love that isn’t in the 2D space and it hasn’t made him a raging misogynist (you CAN be one and not the other!). He just had a massive trauma that left him reeling and it caused him to retreat into a shell he hasn’t escaped from.
Mayuri, their teacher, seemed like an excuse for more boobs and cosplay when introduced, but she actually behaves like an adult here and talks Okumura through some of his issues and helps him realize that it’s not that he’s given up, he’s an amazing friend to all the girls, he just keeps removing himself from the equation so nobody gets too close. It’s a great change of pace from typical manga teachers.
And the Lilysa and Mikari conversation is a belter - Mikari realizes that she’s got no chance in all this, but Okumura is the only boy she’s truly loved. And Lilysa says she has no idea what her love of Okumura actually is and they bond and that’s the end of it.
Maybe not so much.
In one of the best twists I’ve ever seen for a story like this, Okumura accidentally overhears this entire conversation and there’s no misinterpretation or brushing it off. He is now acutely aware that Mikari is very in love with him and he has no idea what to do because he doesn’t return her feelings. In fact, he’s very much giving her what he wants at times and feeling really guilty about it. Guilt!
And then, as he and Lilysa work on capturing the essence of 2.5D characters, actually leaning into that title in a way I thought was terribly clever, she suddenly realizes something herself and it’s just the right time to make things even more complicated.
It’s amazing that somebody finally realized you can admit a lot and it’ll just make your manga that much better. This is all so fresh and complicated that it doesn’t make things any easier, quite the opposite, and I’m really looking forward to where it goes from this point.
And, like I said, it’s really funny in a number of spots. This manga had the absolute dumbest, most idiotic Descartes joke that I have ever seen and I still laughed hard at it. And Okumura’s beach body simply has to be seen to be believed.
There’s a care to this story that belies its ostensible goal to just show some flesh and be done with it. The childhood friend suddenly arises, but they actually give her a real personality that makes it way more tolerable. Plus they set the horny hounds of the student council on her and the council president in another amusing, if predictable, moment.
Yeah, okay, it’s not perfect. This still clearly has lingering aspects of harem going on, even if Lilysa is obviously the one true love for our boy after all this time. And you still won’t like this if you can’t get past its nudity. The public morals officer they introduce this time is looking to annoy the crap out of me going forward too.
Of the two smut/ecchi books in my rotation right now, I am reading Asumi-Chan Is Interested in Lesbian Brothels because the smut’s great and the story is not bad. This one, in contrast, I am reading because the character work is surprisingly strong; the cheesecake is not really a draw for me. It’s absolutely true that this story doesn’t need any - the writing is good enough on its own.
(It is funny that the girls’ costumes do seem set to be toned down in the near future, probably because the anime is coming. But, the in-universe reason being that Aria’s father doesn’t want his daughter wearing such raunchy cosplay that he’s changing the character designs is clever as heck.)
And even beneath the romance(s) brewing, you can see the bonds of friendship between all these characters being formed and they may all be Okumura-focused at various points (jury is still out), but they like one another as well.
5 stars - this story made me laugh and then surprised me with the directions it took and the choices it made, both of which are incredibly hard to do, if I’m honest. I can’t give it any less than five stars after all the work it did to get here and how it paid it all off.

Obligatory summer camp/beach episode, but now with added depth. I came for the cosplay but I got some amazing backstories, discussions, and wholesome stuff. I love this manga!
Another childhood girl appears and is it the one who our MC loved? And the culture fes is coming? Yas!!
