Nijiiro Days follows the colorful lives and romantic relationships of four high school boys—Natsuki Hashiba, a dreamer with delusions of love; Tomoya Matsunaga, a narcissistic playboy who has multiple girlfriends; Keiichi Katakura, a kinky sadist who always carries a whip; and Tsuyoshi Naoe, an otaku who has a cosplaying girlfriend.

When his girlfriend unceremoniously dumps him on Christmas Eve, Natsuki breaks down in tears in the middle of the street and is offered tissues by a girl in a Santa Claus suit. He instantly falls in love with this girl, Anna Kobayakawa, who fortunately attends the same school as him. Natsuki's pursuit of Anna should have been simple and uneventful; however, much to his dismay, his nosy friends constantly meddle in his relationship, as they strive to succeed in their own endeavors of love.

This is one of those series that finish so fast once you start watching, because it is just so relaxing and nothing too serious happens, which also makes it so relatable and reminiscent of our high school days (well, for those that have graduated at least!) or how it could be. If you are looking for an easy-going series filled with the power of youth, this is a good example.

Story-wise, there is nothing specific as it is their everyday life, but the overall feel is focused on the romance part; 4 friends who tease each other and their romantic interests. We see everyone’s view (not read more

At first glance, one would think that this is a yaoi anime, but even without the "shounen-ai" tag, it's not. It's one of those rare romance anime where the main characters are the same gender, but the romance is heterosexual. When I first saw this anime, I thought probably the same thing as anyone else who was unfamiliar with this anime before it aired, "This is going to be another borderline-yaoi anime, is it?" Then, I read the description, and my curiosity was piqued. For that reason, I ended up watching it when it premiered, and I must say that it was a fun anime read more

Prewarning: If you want something intellectually challenging, or awe-inspiring, this isn't for you. If you don't mind stereotypical plots, a bit of laughter, and are looking for something simple to watch and not think too much about: Sure, go watch this, knock yourself out and have some fun fawning over cute characters.

I really enjoyed this show at the start, and had it ended after one cour I'd probably have given it an 8. To begin with the characters are fun and there was no major drama. Sure it played on typical relationships and character types, but in a light-hearted and happy-go-lucky manner. What was also read more

What Norn9: Norn+Nonet couldn't do, Nijiro Days did better with LESS screentime, ohh well ok nearly the same screentime but whatever.

Nijiro Days being an anime short consisting of 24 episodes with only 10 minutes is about the 4 differing relationships of the four main boys of the anime short. As such LA is very thankful that this anime short has this kind of screentime let alone episode count as it would have been rushed to all hell, nonetheless due to this the majority of the relationships go in depth to.

Though LA says this, the majority of the focus goes to Natsuki "Na-chan" Hashiba voiced by read more
