Appearance
Tsuzuri strongly resembles Nae Tennouji as noted by Suzuha Amane by her physical appearances as she crosses paths with Tennouji.

When she first met him, her hair's colored Coyote brown, extended long and down to her hips. After she and Tennouji married and gave birth to Nae, she fixed her hair into a ponytail hanging down mostly above her right shoulder.

Personality
Tsuzuri is introduced as a kind, mature, grateful and enthusiastic woman when she thanks Yugo Tennouji for stopping a thief to retrieve her handbag back and getting to know him as a slightly rough but kind man whose slightly rocky relationship with Suzu Hashida improved thanks to her involvement as the mediator. She's also somewhat clumsy, tending to trip or bump into things by accident.

Even after discovering Tennouji was employed by the Rounders; a wrong kind of people to work for and the fact that he was asked to eliminate Suzu, she held no ill will towards him and was selfless enough to volunteer to be a Jellyman experiment by SERN against her will as punishment for him to make sure that his and Nae's safety is guaranteed not afraid of dying.

Background
While Tsuzuri wasn't her student, she was already acquainted with Suzu Hashida in the past a knew her to be a Physics professor at the local university.

Braunian Motion of Love and Hate
Tsuzuri first met Yugo when he stopped a purse snatcher who stole her bag, only to be mistaken for the purse snatcher and knocked out by Suzu Hashida. After he woke up, they introduced themselves.

When SERN busts in to come after Suzu's laptop and punish Yugo for his insubordination, Tsuzuri offers herself so Nae wont be harmed. However, still under the impression that they would return her soon, Tsuzuri leaves after revealing that she is pregnant. She was then jellified by SERN, with her corpse being shown to Yugo. The SERN agent then told Yugo to make up a story surrounding her death.

Steins;Gate
