Rei Nasu

"I don't know how many matches we'll have left. So... let's take the top! This is our last chance to do it with the four of us."

- Rei Nasu to her teammates

Rei Nasu is a Shooter and the captain of Nasu Unit.

Appearance
Nasu is a slender girl with delicate features and turquoise eyes with no pupils. She has neck-length ash blonde hair styled in a bob cut with blunt bangs. Her eyes change slightly in her trion body because she becomes more energetic.[BBF Q99] She often wears button-up jackets over light-colored shirts. Her uniform consists in a futuristic-looking white body-fit top with a square collar, purple gloves, an indigo belt that wraps partially around her waist, and a shoulder strap exposed on her right side. From the collar peers out the hem of a black shirt with a V-neck. The uniform sports six fake buttons arranged in two columns of three and a seventh right underneath the collar, on the right side; on the left is Border's emblem. The attire is completed by short black pants that connect into long purple boots.

Personality
Nasu is calm, well tempered and hardly gets carried away. Despite her frail appearance and constitution, she is strong-willed in battle and maintains a cool head under pressure. In the match against Tamakoma Second and Suzunari First she demonstrated an iron will which was not in small part motivated by her deep affection for her teammates and the resolve to climb as high as they could before Hiura had to leave. The only time Nasu displayed any semblance of anger was when Wen Sō disguised herself as Kumagai.

Yūko Kumagai
Nasu and Kumagai share a strong friendship and care deeply for one another, so much so that Nasu was outraged by Wen Sō disguised herself as Kumagai and, right before defeating the Neighbor, she claimed that she was taking revenge for the injuries she had inflicted on her friend.

Akane Hiura
Nasu cares about her teammate and found more motivation to rank higher when she heard about Akane moving.

Tōru Narasaka
Rei is Narasaka's older cousin by three months, and she is the one who asked him to mentor Hiura.[BBF Q127]
