Senna
Senna is a young girl with purple hair and a red ribbon tied to it. She has large, orange eyes and is usually seen in a brown school uniform. When she transforms into a Shinigami, Senna wears the standard unseated shinigami uniform with a large, red ribbon tied around her waist.
Senna likes the color red and high places. She’s also very curious, constantly darting from place to place. Although she is haunted by brief, randomly-appearing memories of “her” past, Senna generally exibits a spunky, upbeat, and carefree personality.
As stated by Ichigo, Senna is additionally strong-willed, stubborn, loyal, and somewhat outspoken.
Senna also has Shinigami powers and a Zanpakutō. Rukia reveals her Zanpakutō was lost 100 years ago in the Severed world. However, it wasn’t revealed as to how Senna obtained her Shinigami powers or her Zanpakutō.
Besides her Zanpakutō, and ability to control Blanks, Senna has shown to be skilled in swordsmanship, and an agile fighter and gymnast. Even in her gigai, she is very agile, able to perform several backflips at once. It is implied she is adept in Flash Steps when she falls and seemingly disappears, reappearing behind Ichigo during a tight-rope walking performance at the Karakura Mall, fooling even Ichigo, who is an expert in Flash Steps himself.
Shikai: Her zanpakutō is released by the command “Call forth the Twilight” (夕闇に誘え, Yūyami ni izanae; “Bring them to the twilight” in the English dub). It takes the form of a Khakkhara when released.
Shikai Special Ability: Mirokumaru has the power to create and control tornadoes.
Near the end of the movie, when Senna is about to sacrifice herself and Ichigo attempts to stop her, she states that she’d rather sacrifice herself than see Ichigo die, implying that she may have developed romantic feelings towards Ichigo during the time that they spent together. The same might be said for Ichigo, as when he went to a store to buy Senna’s trademark red ribbon, the female clerk questioned if it was a “present for his girlfriend”, to which he slightly blushed at that query and quickly dismissed it (“not quite” being his reply in the original Japanese version; he insists that she was his “sister” in the English dub). She also went into a brief state of depression when she assumed that Ichigo was killed during his first battle with the film’s main villain, Ganryū, after witnessing Ganryū impale Ichigo with his spear.
After the credits, it shows Ichigo travelling to school when a strong breeze of wind blows a red ribbon to him, upon touching, it seems that Ichigo remembers something. During that time, a loud and energetic girl came running past which resembles Senna and Ichigo smiles and walks away.
