Naoto Tachibana

Height: 148 cm (past), 175 cm (present)

Hinata's younger brother. He very much resembles his father.

Naoto is a righteous individual who is also determined to also save his sister. He has a no-nonsense personality and is usually unamused by others' humorous advances. He is also willing to embrace far-fetched possibilities, such as the fact that Takemichi can time-travel, and even make his own hypotheses about it.
