Hitagi Senjougahara

Height: 165 cm

Hitagi, the main female character, is a weak-looking girl with an "incurable disease". She is in the same class as Koyomi, but he has almost never heard her speak. When she was in the first year of high school, she encountered a mysterious crab, after which she became weightless. Ever since, she has avoided contact with everyone else, threatening everyone who discovers her secret. She called herself a tsundere and always speaks in an abusive style.

At the end of Mayoi Snail, she admits that she loves Koyomi, and subsequently enters into a relationship with him.

After the events in Tsukihi Phoenix, she overcame all of her trauma, and became a rather cheerful and normal girl. She starts calling Araragi with a cute nickname, chuckling at small things and sending e-mails full of Emojis, although her sharp tongue is still there, but toned down.

Hitagi has told Hanekawa that she suffers from an Electra Complex (when a girl has intense sexual attraction towards her father). Whether this was a joke or a sincere admission has remained unrevealed
