凪 九厘

Natsuki's classmate and friend in 1999. She looks and acts cold toward men but not against women.

She and her father take care of housing Tsukumo in 1999 and provide him with what he needs. It is also them who invented an identity for him in order to infiltrate the society of 1999, it will now be for the outside world "Nagi Tsukumo". Kuurin's role is to be his "guardian", she will pretend to be his non-blood-related sister.

She is idolized at her high school, called "Onee-sama" by her classmates ( Tsukumo will be called "Onii-sama" because it is supposed to be her brother ). She takes advantage of her notoriety to seduce girls in order to have sex with them.

Her personality is quite similar to what she has in the present time, although she looks more ... explosive and bitter.
She is stronger than Tsukumo in singular combat.
She makes fun of him by calling him "Saru" ( monkey ) and because he is a huge siscon, calling his sister in his sleep.
Her favorite perfume is vanilla.

She has been the victim of horrible events in the past - who are at the origin of her hatred towards men - and makes nightmares about these events every time she falls asleep, but doesn't really remember in what she was afraid when she wakes up in panic.

Despite all of this, she looks to appreciate Tsukumo or she just considerates him better than the other men she despises.

The trait "Sex with Others" concerns her and Yurika because they sleep together.
There maybe other girls with whom she sleeps in off screen but not with boys./
