It’s All Your Fault, Vol. 1

全部君のせいだ [Zenbu Kimi no Seida] #1

by merryhachi

Shiho Kumai is a broke college student and hardcore otaku who lives for cosplay, but she just can’t find a way to share her passion with the world. Enter a fellow cosplayer who loves the hobby just as much as she does, adores the same anime, and (to top it all off) has over 200,000 followers on social media! It’s a match made in heaven for Shiho…until she finds out Yotogi is one of those cosplayers—a person who disregards the source material to be extra risqué! They make a great pair, but can the two move past their differences in costume philosophy to become real cosplay superstars?!

Boy, this took a while to get through, which can sometimes mean that I’m not vibing with a story. But this horny mess has a vibe like nothing else I’ve read in a while.

Take the cosplay affinity of My Dress-Up Darling and 2.5 Dimensional Seduction, mix in the general horniness of the two, especially the latter, now make it about two polar opposite college girls and turn it into a yuri. Now that’s a recipe for manga!

Stories like this where nothing should really work, yet somehow most things do, are pretty enjoyable. Shiho is our lead, whose prickly obsession with cosplaying hardcore has scared off her few friends. She’s unapologetically a lot to take and occasionally not the most enjoyable character to be around, but she is very honest about wanting to both make excellent cosplay and have friends who get her passion.

Yotogi, meanwhile, is less about character purity or any kind of purity, and is a much more softcore cosplayer. A chance encounter and some bunny costumes later and a couple of weirdos become fast frenemies who can’t stop hanging out together.

This builds on itself to get really good by the end. After Yotogi and Shiho start bouncing off one another, it becomes clear that the whole book is going to be about them finding a middle ground between their two extremes. And I do love a good story about finding your people.

Yotogi is unflappable and blasé about showing skin, while Shiho won’t unless it makes sense for her character. And the way Yotogi just throws staying in character out the window to accommodate her burgeoning social media account riles Shiho up something fierce.

Of course, they learn as they go that both their styles have merits. Shiho turns out to be easily addicted to fame and wants approval more than she lets on, while Yotogi learns to not just give herself up to anybody unless she really wants it. Role models they aren’t, but they do begin to work well together.

And the manga is having fun with itself anyway. When the second cosplay they do is based on a fictional adults-only yuri title about polar opposites who end up having hot and heavy encounters, you know the mangaka is just leaning way into it.

Oh, yes, and the president of the club they join looks way younger, yet just might be dating Shiho’s older sister (I actually loved this development, it was hilarious). There’s just a lot to this if you’re into these cosplay stories and like playful yuri. It probably dumps on Shiho a little too much at the start, but she does ride in on a pretty high horse.

For you smut aficionados, and I will first say it’s nice that they’re all in college, this is… okay. I think the other two cosplay series I mentioned do the sexy stuff better. This is not the book I’d go to for cosplay titillation, frankly, but I think it has merit beyond that.

Dubious merit, perhaps, but I have rarely read anything with such combative leads that I enjoyed this much. It’s worth wading through an alright start to reach the ending. Shiho might be a bit predictable being the hero, literally, but it suits her. And the last scene between her and Yotogi is very hot with just a word.

3.5 stars - 3 stars at the beginning, heading into 4 by the ending, and then rounded up for making something I wasn’t sure about into something I’m really looking forward to seeing more of.

This was a fun series start about college students and their love for cosplay. I appreciate that the story shows that while the characters may be different in how they express their passion, each of their methods is valid. And that women in fact can be sexy for themselves. There's a potential main couple and a possible side one and the chemistry is great for all involved. I'm definitely excited for more.

'My Dress Up Darling' but but messier, gay, and enemies to lovers.

A fun, chill read about cosplay adventures and unexpected friends. I look forward to reading the next part in the story to see what comes next!

TW: consent issues, underage looking character

As a cosplayer and yuri fan, I had high hopes for this manga. It started out promising, but quickly turned into a uncomfortable read due to consent issues/coercion between the main couple. In addition, I was really confused on whether one of the characters just looked really young for a college student or was actually a kid. Either way, the suggestive scenes with said character made me very uncomfortable. I did manage to finish the volume since I didn’t want it to be a waste of money, but I am DNFing the series. This was super disappointing as so many yuri series that have been localized in English are about high schoolers, and I was looking forward to this not being about that. So yeah, reader beware.

It’s like a yuri My Dress Up Darling, but with actual adults, and a fun, spicier twist on the whole thing. It’s an ecchi series, and it knows it, but it doesn’t go cheesily over the top, or rely on a bunch of “innocently walked into the changing room” type scenes to bring the spice.

I also like the ‘spicy’ parts in this series a lot better than its inspiration because it feels deliberate in a refreshing way. The ecchi delivers without feeling as opportunistic as some ecchi series do — is one way I might put it.

I don't think I'm going to continue this series 😔 The premise sounded fun and sexy cosplays vs not is a culture clash I never considered but instead of being interesting it was just an excuse for sexual harassment. Then, to add insult to injury there's a character who looks like a child but is actually older than the main character and oh, she sexually harasses the main character like wild on top of it all. Great. Brilliant.

Many things going on here. Personally I'd be a bit weirded out if my sister tried introducing me to the porn she reads, but to each their own?
On a separate note, glad to see that they're not playing off the crossing of boundaries to just be a funny little gag

Hier hat mich die amüsante Beschreibung gelockt und war wirklich gespannt. Hat mich wirklich überrascht die Geschichte. Auch wenn das nicht unbedingt mein Genre ist, werde ich die Reihe evtl. irgendwann einmal fortsetzen. Humor war auf jeden Fall da und die Zeichnungen waren auch gut.

[Mickey · Rating 3 out of 5]

Fun, but kinda has this weird thing going on where it's trying to be both genre aware and trying to uphold it's own genre. (Aka the character in this read and comment on yuri and some of its recurring tropes even as those tropes play out. Which is an odd dichotomy.)

Full review later.

This one didn't really work for me, despite the subject matter being right up my street. Ah well.

Needs to be more freaky👀

[Karina · Rating 3 out of 5]

Overall this was fun but took me awhile to get through, not sure what put me off. Probably because Yotogi looks like a child 🙄

[Jacob · Rating 1 out of 5]

Made it half way through volume 2 and it just wasn’t my thing. I have so much to read rn that I jus put it down might return later though

[Ro☆ · Rating 3 out of 5]

was this kind of a horny, over-sexualized mess? yes. did i have a fun time reading it? also yes.

[Kimberlyyyreads · Rating 3 out of 5]

Idk how to feel about this, I might read the following vol but I’m not sure either 😭

Review to come🤍

[Alicia Alaniz · Rating 3 out of 5]

It was alright. I thought I was a Yuri book but it’s giving off hey we’re friends now and we gotta cosplay now.
Which in some parts it doesn’t seem like flirting? I feel like it’s considered yuri because they are close only for the photo shoot.

I was expecting more of a slow burn for the characters but there isn’t even a small fire or spark.

Tämä tuntuu raikkaalta! Enemies to lovers My Dress-Up Darling vähemmän alaikäisillä hahmoilla. yuriversiona! Haluan nähdä näitä päähenkilöitä enemmän. Piirrostyyli on siisti ja moderni.
