Najimi Osana ( (おさ) () なじみ Osana Najimi?) is a person whose gender is unknown. They are also the complete antithesis of Komi Shouko; possessing phenomenal communication ability to get close to anyone within a few minutes of meeting them.


Najimi sports a short lavender and wavy hairdo that spikes up at the ends. They have a petite body and is below average in height for both male and female. They appear with wearing shorts and a t-shirt when they met Komi in elementary school. When they befriended Hitohito they are seen wearing the gakuran for middle school students and requests that people use the masculine suffix -kun when referring to them. Once they got to high school Najimi appeared as a girl wearing the female uniform skirt, but male necktie as clothing in general.

They sometimes wear either male or female clothing outside of school, often wearing androgynous clothing when hanging out with friends.


Najimi is known for having exceptional talent when it comes to communication. This paired with the fact that they frequently transferred schools growing up has lead everyone in Itan Private School to being their childhood friend, including Hitohito, whom Najimi notably knows the dark secrets of. They became the vice president of Class 1 because of their talent.

They met Shouko for the first time when they were a second year in elementary school, but due to Shouko's inability to speak, she broke Najimi's streak of making friends; causing them to be bedridden for a week from shock.

In high school the trauma follows them and causes them to shake when making eye contact with Shouko. Initially, Najimi rejected Hitohito's plea to befriend Shouko. However, after much begging, they reluctantly agreed. When walking home with Shouko and Hitohito, a former classmate confessed to Najimi and attempted to assault them when he was rejected. Shouko noticed that the assaulter dropped his keys and attempted to returned them, but was unable to get the words out and unintentionally scared him off with her tense expression. After this, Najimi decided that they liked Shouko and would help her make more friends.

They insist on using the feminine suffix -chan but has been known to switch back to being referred to as a boy when convenient: like when rejecting a male classmate that confessed.

Other characters often use both male and female pronouns when referring to Najimi due to nobody, even teachers, knowing their birth gender.
