Nijiiro Days is the story of four high school friends who are having a wild and wild romance. Natsuki is a die-hard romantic who is always searching for true love. Tomoya is a total playboy who is self-absorbed and has multiple girlfriends. Keiichi is a slightly strange, headstrong, and Tsuyoshi is a dedicated computer-gamer otaku whose girlfriend has a penchant for wearing unusual clothes.
When Natsuki’s girlfriend cheats on him and runs away on Christmas night, he breaks down crying in the middle of the street. A girl dressed as Santa Claus, Anna, sees him crying and gives him a tissue, and Natsuki falls in love with her at first sight. The funny thing is, the girl turns out to be from his school. Setting up Natsuki’s scene was easy, but his cunning friends interfere in his every move, even as they themselves are involved in some kind of affair.
