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 Yoshitsugu Matsuoka and Anna Kobayakawa voiced by Minami Tsuda's relationship from friends to a couple. The other closest relationship with this kind of focus goes to the incredibly shaky relationship of Tomoya "Mat-tsun" Matsunaga voiced by Takuya Eguchi and Anna's best friend Mari Tsutsui voiced by Yumi Uchiyama. Unfortunately the other two relationships of Yukiko Asai voiced by Shizuka Ishigami and Tsuyoshi "Tsuyo-pon" Naoe voiced by Kouki Uchiyama as well as Keiichi "Kei-chan" Katakura voiced by Nobunaga Shimazaki and Tomoya's little sister, Nozomi Matsunaga voiced by Ai Kayano gets *ahem* pushed aside for the other two more focused relationships and are more or less B plot relationships with Tsuyoshi and Yukiko's relationship was already formed before the anime thus didn't have enough meat and Keiichi and Nozomi's relationship started rather late to get a proper focus respectively. LA's favourite relationship oddly enough however goes to Tomoya and Mari's relationship, yes LA could say that Mari's constant bickering to Tomoya got annoying rather quickly but their development helped a bit more especially with Mari's defrosting and deredere moments.
The animation by Production Reed at best is above average for an anime short and LA had really no problem with the animation at all.
Voice acting wise, there was an annoying voice acting mainly from Yumi Uchiyama who voiced Mari but she got better over time (away from her bitchy vocals anyways), however LA's favourite voice actor in Nijiro Days would actually be Shizuka Ishigami who voiced Yukiko and really LA wanted to see more of Yukiko but again for her character' circumstances, LA could see why she couldn't.
The ending for Nijro Days gave us something of an "ok" ending as the entire focus for the final few episodes went to Anna Kobayakawa's revelation about her relationship to Hashiba and really it's the typical "can't spit it out" by the end of the anime, ohh Anna finally gets her revelation about her growth to her relationship to Hashiba but she just doesn't take the move to grow it even further, nonetheless, the sentiment was nice, the ending also the narrow focus, all the other relationships are put in limbo to give the focus to the main couple of Hashiba and Anna, it's a bit of compensation at least but LA wished the focus was split a bit more to the rest of cast and their relationship. The ending is really a double-edged sword but LA overall was slightly satisfied with this ending.
Nijiro Days is a great romance anime short to the anime short medium that looks at many stages of a relationship with lots of growth to the multiple relational developments, sure the focus tends to go to Mari and Tomoya and especially Anna and Hashiba while the other two relationships turned into a pseudo-growth/supporting characters to the above relationships. Nonetheless Nijiro Days is a soft-fluffy puppy-love anime short with some good payoff of relationship growth here and there.
