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.

Hibiki Amami would be a regular high school girl if it weren’t for one thing: a sixth sense that allows her to see ghosts. Rather than being scared, Amami is more interested in befriending and helping the apparitions. This often leads to her human friends witnessing paranormal activity as the ghosts try to help Amami with everyday tasks. The majority of Amami’s friends accept that she has a sixth sense, but Narumi Inoue—a girl who is terrified of the supernatural—refuses to acknowledge that ghosts are real. Though she is scared and stubborn, Inoue goes along with the rest of her friends, who decide to take up Amami’s mission of helping ghosts however they can. [Written by MAL Rewrite]
