This series is starting off with a lot of fun and humor!

This series follows 4 teenage boys as they find their way through romances in high school. Our main hero, Natsuki is a romantic at heart. Each of the boys is very different, and Natsuki is truly a little oblivious to how things work. When he's dumped by his golddigger girlfriend, he offers a stranger who looks cold a scarf. She takes the scarf, and starts wearing it constantly. When Natsuki sees her at school, he believes it's fate!

Pick up this volume to see how he and his 4 friends handle what is thrown at them in the series!

Rainbow Days hat mich ziemlich positiv überrascht. Es war gute, seichte Unterhaltung und der Zeichenstil hat mir gut gefallen. Die Truppe, um die sich der Manga dreht, ist manchmal einfach unmöglich, aber ich habe viel lachen müssen. Bin gespannt auf Band 2! :)

This was fun!

I wasn't a fan of Katakura and think he is my biggest "hurdle" with this series in picking up more volumes physically because I just didn't love his whole sadistic thing and breaking out his whip.

On the flip side though, I LOVED Hashiba! He is such a fun and super-sweet hero to follow that I couldn't help but smile at how hard he tries and how earnest he is! I felt sad for the many times he gets picked on by his friends, but it does seem they genuinely care for him and are rooting for him with the girl he really likes.

I also really liked Naoe! Once his girlfriend appeared, and I saw how they were sort of a grumpy x sunshine kind of relationship, it's where I really wished I had more volumes because I love them already! They seem like they will be such a fun couple, and if I knew that these two and Hashiba were the main focus moving forward, I wouldn't hesitate to pick up more volumes for sure.

I'm definitely glad I tried this first volume because it was unique in that it had an all-boys cast of MAIN characters. That's the first time I've read a shoujo like this and I think it will be one I'll remember because I did like how interesting everyone is!

Overall, I would like to continue on the VIZ app because I want to see Hashiba succeed and want to see more of Naoe with his girlfriend!

As Christmas approaches, Natsuki finds himself incredibly unlucky in love, but a chance encounter has him head over heels. And to achieve his wholesome goals, he’ll get by with a little help from his friends… or not…

High school boys of a certain type have the enthusiasm and excess energy of a chicken coop in a lightning storm. These are those boys and, as the manga helpfully states early on, this is the story of them and also how they’re kind of dumb.

And this is, consequently, one difficult story to review. Let me be clear, I like this book and it has an energy to it. Said energy can be a lot to put up with, however, which in a way makes it the most accurate simulacrum of high school boys I’ve seen in some time (also I am old and crusty and have been since I was 18). Accurate, but it can be tiring.

The boys in question run the gamut from the generally nice Natsuki to the S&M loving Katakura (minus the jokes this is treated better than I expected it would be), the five-timing Matsunagi, and otaku Tsuyupon (who might be the most adjusted of them). Minus some important caveats, they are the essence of the friendship where, when the chips are down, you have one another’s backs, but that back is also an awfully tempting place to lodge a few daggers.

Playful meanness is the order of the day and if the story is not necessarily hysterical (okay, I laughed at the chocolate Gunpla), it tries its damnedest and if you like dialogue that runs like an electric current, you will be well served as these clowns repeatedly dunk on one another like they were the Hokkaido Globetrotters.

And amidst all that, Natsuki just might find himself chasing the quiet Kobayakawa while abetted and abetted by everybody around him. Kobayakawa is so quiet she’s just this side of boring, although I’m half tempted to call that a commentary on all the thin as paper male leads in most shojo.

A majority of the jokes are of solid quality; the way it flips some tropes on their head, especially the ‘guy coming to the rescue’ one, is pretty amusing. How they managed to fit in a Valentine’s baking scene despite it being all boys is just clever enough too.

And while the guys start out fairly irritating, this quickly turns into an excuse to dump on them as they so richly deserve. While it seems they may sit atop the heap, the reality is far, far from it and that’s a fun contrast.

The problem comes when the lads are at their bro-iest, which unfortunately makes Matsunagi a super problem in this volume. He’s a player who gets played easily enough, but becomes way too forceful when Kobayakawa’s man-hating friend enters the picture.

She’s very over the top as well, in a way I don’t think you’d see in a more modern series (despite the release date here, this was initially published in 2011). But that doesn’t excuse Matsunagi deciding that consent is something that happens to other people when he kisses her out of nowhere (consent comes up in the S&M stuff, so it’s even more odd how this plays out).

Again, a different time, but I’m not gonna pretend that didn’t happen and it really soured me on the story a little bit. When they’ve got their sights set on aggravating one another, the guys are fine, but having it spill over to something like that is less so.

Overall, however, it is a mostly positive experience that I’ll give another couple volumes to in order to see where it lands for me. Missteps aside, it’s a pretty unique take on the genre. That all said, if the above stuff is an emphatic ‘no’ for you, fairly warned be ye, says I.

3 stars - strip Oh Maidens in your Savage Season of its messages and flip the genders and you’d basically have this examination of romance and mating in high school. It’s not off to a bad start, but I will keep my eyebrow raised for some of its less savoury concepts as it moves forward.

This book features a scene in which a character explains she has romantic feelings for her female best friend and hates men and the male character she is speaking to then kisses her out of nowhere. When the female character is rightfully disturbed by this action, the male character thinks it is “cute”. Wish I’d never read this shit.

Icip vol.1-nya dulu karena terseret arus hype sepertinya lucu~

.....mungkin seharusnya aku ga ngarep kalo ini bakal selucu Nozaki description
Aroma yang terendus dari vol.1 ini lebih mirip Bocah Seiho ~ Sama-sama nyeritain sekelompok remaja pria yang haus kasih sayang...XD

Bukannya mau menista "remaja pria" maupun "kasih sayang", cuma rasanya rada geuleuh ngeliat bocah yang "ceria dan jujur" itu XD Yah.., namanya juga bisnis~ ( ͡° ʖ̯ ͡°)

Tokoh utamanya, si Nacchan, lebih mirip cewek ketimbang cowok XD Romance-nya Nacchan yang serba gugup dan salah tingkah ini manis juga sih~

Gambarnya oke (^ ^)

Aku belum tau apa akan lanjut atau brenti sampai di sini saja~ ☆ミ(o*・ω・)ノ

I am reasonably certain that I reviewed the anime version of this title and that it didn't leave much of an impression on me, so I'm delighted to say that the manga is much more fun. Why could simply boil down to the book being better than the adaptation, but whatever the reason, Rainbow Days' first volume is a goofy little confection about four guy friends with their own little quirks that may or may not work out for them. There's enthusiastic sadist Kei, hapless Natchan, playboy Matsun, and otaku Tsuyopon, and together they're a mismatched bunch. As the volume goes on, Natchan falls hard for Anna, who is guarded fiercely by her misandrist friend Mari, and I really don't like how Matsun acts around her, but that's the only major fly in the ointment. Mostly this is just fluff and fun, and while it isn't likely to knock your socks off, it is a pretty fun time.

This is a shojo manga from the boys POV, which was interesting in and of itself (mostly because I haven’t read anything like it yet). It follows four guys, all best friends, as they venture through love. The boys are absolutely depraved lmao. Like, they start out all sweet and adorable and then they do things that had me like HUH. But I enjoyed their dynamic together and how involved they all were in each other’s lives. This first volume focuses more on Natsuki, but I’m excited to read about everyone else too.

TBH, I started this because I liked the ongoing anime, so much that I didn't leave a page from the manga!! It's like Horimiya, light and sweet yet so interesting. It's about the 4 boys in high school going through situations that all high schoolers go through. The anime is so colorful, just like the name suggests. Nijiiro Days = Rainbow Days.

I am sure that the manga pages would be colorful too if it would be in color and not black and white like it has to be. Hehe! Characters are super interesting, cute (Natsuki) and soo damn hot (Tsuyopon, Kei-chan, and Matsu) (*~*) The guys are all unique, one is so sweet that I guess other have diabetes due to him, one is a sadist, one is an otaku and the other one is a playboy. They all get the equal amount of character development through the series. The girl characters in this manga are also very interesting, except Anna, who is the main character, Natsuki's love interest. But I hope to see a chapter devoted to Anna, to show who she is or what kind of a person she is as a person, because I think all the characters have shown their good, bad, fun sides of themselves, hell even Matsu's sister Nozomi's character got few scenes for herself to develop and fall in love with one of the main characters. The most annoying character would be... MARI!!!!!!!!!!!! (-_-) okay, I'm calm. But later in manga we come to know why she behaves cold and irritated by everyone except Anna. Poor Mari-chan.
Artwork, like I said colorful.. in the anime and on the covers... but inside the manga too they are just so neat and clean, no rough edges the smooth kind. they all have different features and styles.
Anyway...... this manga is super amazing! Give it a try, okay!!

This was pretty underwhelming. The fact that it wasn't queer felt like a bait and switch (why call it Rainbow Days?) and I didn't really like the guy characters. I found it very strange to include several references to kink/BDSM in what was otherwise a very tame, high-school appropriate story.

My biggest issue was that one of the male characters has a female character confess to him that she has feelings for another female student and that she doesn't like men at all. In response, he kisses her out of the blue and she is appropriately disgusted and appalled. His response is to think her anger is cute/funny and it's never addressed again. That's pretty heinous behavior and this scene alone is enough that I can't recommend this to anyone.

There's also a mini arc at the end where a male character calls another character 'ugly' and it's supposed to be ok because he is showing affection/using it as a term of endearment.

The rest of the content was fine, but nothing remarkable. I will not be purchasing this for my library. Digital ARC received courtesy of NetGalley.

This was surprisingly funny. I wasn't expecting it to be this comedic. Right now, I'm having trouble telling the difference between Keiichi and Tsuyoshi because they both look sorta similar (they both look like they have black hair, even tho Keiichi has dark brown hair).

The sudden kiss scene was weird.

5 star for the premise and the illustration.
It is refreshing to have guy as main character in shojo manga. I love their friendship but overall story is just fine or maybe my expectation that is too high. Overall, I like it.

This is a fun and sweet manga about four high school boys and how they are learning to navigate both friendships and romantic relationships as they grow up.

Often, I find some manga set in high schools to have characters that seem more like caricatures than anything else. There’s this impulse to make teenage characters almost more juvenile than necessary. But, this manga does such a great job at capturing young, male characters that feel genuine.

I appreciate how this mangaka seems to appreciate the nuance and vividness of youth, growing up, making friends, and falling in love for the first time.

Definitely looking forward to reading more~

Nach 50 Seiten abgebrochen

Ich greife eher selten zu Manga und da war Rainbow Days wohl einfach nichts für mich. Es passiert einfach so viel, ständig reden Leute durcheinander und ich war einfach so verwirrt, dass ich nach einigen Seiten einfach keine Lust mehr hatte.
Das ist tatsächlich auch mein zweiter Versuch mit dem Manga, weswegen ich ihn wohl aussortieren und es vielleicht mal mit dem Anime probieren werde.

I wanted to enjoy this book, but it was just ok. I don't know if the watermark made me missing important dialogue or if it was just too chopy for me to follow. I didn't dislike Rainbow Days, but I won't be continuing the story. Maybe I was just not the target audience.

3 stars.

Two of the male leads are trash. No, I don't want to read about a teenage dom, and no, I don't want to follow someone who tries to make cheating an Olympic level sport. The other two guys aren't enough to elevate this.

No thanks, dropping this like it's hot garbage 👎

Interesting enough that I'll read a few more volumes. The boys are basically stereotypes of numerous tropes so they may start to annoy me, we'll see I guess

Cute and funny start into a manga series that might have the potential to become one of my favourites, depending on how it develops. So far I really enjoyed getting to know sweet, innocent Natsuki and his slightly strange but still lovable bunch of friends, who all have their own ideas of their ideal girlfriends and ideal relationships. I am already cheering for Natsuki and his current crush and really hope those two will find together. For the other boys, of course, I want them to become happy too but let's see if their relationship approaches will lead to a happy end. So far, some of them seem to have rather unhealthy types of relationships behind them (or before them?), we'll see how it'll go. I really enjoy the art style too, by the way, it's rather simple but beautiful, while still not too girly. I already bought volume 2 - 4 to keep reading and I admit I was really excited to see that the series is already released completely in my country so that I can binge-read it whenever I like :3 The bright side of being late to the party haha!

Thank you to Netgalley and Viz for this arc in exchange for my honest review.

Four high school boys are close in friendship, but their personalities couldn't be more different! We meet Hashiba, Matsunaga, Katakura, and Naoe- all who have a very different take on being in love.

Through various romantic circumstances, we see this group handle such holidays as Christmas, Valentines Day, and even final exams! The boys have very interesting personalities- all mixing and creating a fun story with humor, love, and friendship.

Overall I enjoyed the comedy and banter the characters brought to light, but occasionally I found myself not being able to keep up with the dialogue. Sometimes it was hard to follow who was taking, especially when there were 5 characters in the same scene. The art was decent, but lacked the heavy detail I usually enjoy. Overall a solid 3 star read.
