Appearance
Tetsuya has red eyes and short red hair. (TBA)

History
Tetsuya is oldest child in his family, the only other child being his younger sister by two years, Momo. His parents had to travel a lot because of their work, so the two of them would stay at home alone from early on. This meant that both Momo and Ten took on responsibilities around the house.

When he started middle school, Ten left the family to live on South Cross Island to attend South Cross Middle School which he has graduated from. He is currently attending South Cross High School.

Etymology
Tsunashi (十) - ten; however this is not a real name. The name comes from the fact that most numbers are counted with the counter "tsu", but "ten" doesn't have that counter, leading to the invention of "tsu-nashi", meaning "without tsu" ("nashi" means none/without). It also looks similar to the letter Taw, the Phoenician letter connected to her. Alt. spelling: つなし

Tetsuya (てつや) - kanji spelling: 徹也, composed from "徹" meaning "clear, penetrate, pierce, sit up (all night), strike home" and "也" meaning "to be (archaic form)"

Ten (テン) - ten, like the number (10)

Relationships
Tsunashi Momo - His younger sister by two years. Shortly after Momo moves to South Cross Island in search of him, she finds him and moves in with him. He moved out of their family's home for school and Momo starts looking for him because their parents are often out on travels for work purposes. He later finds out about the PreCure's identities.
