Matsuri is a strange girl Yorito met early on in the story. She is a Yaka being, a "Calamity of the Night", and she cannot come in contact with direct sunlight as it harms her, thus, she never saw the sky in all its grandeur. Her greatest wish is to one day stand under a true azure sky, just like in the pictures.
Mana is Yorito's friend from school; she often gets annoyed at Yorito for how he spends so much time taking photographs of the sky instead of spending more time with his sister. Mana works as a waitress at the Azure Restaurant and often comes over to Yorito's house to cook for him. She looks after her younger sister Koyori. She also knows about Matsuri's secret.

Takeshi is an older man who is trying to track down Matsuri. When fighting her, he wields a large sword unaffected by Yaka powers with the intention of killing Matsuri and uses ultraviolet lamps to try to immobilize her.

She is Kuchiki Rukia's Zanpakutou in physical form. Living up to its name as the most beautiful Zanpakut� in Soul Society, Sode no Shirayuki manifests herself as a beautiful woman dressed in white and light blue clothes. Her hair is pale blue and she speaks softly. In its released state the blade becomes completely white and a ribbon forms from the pommel, earning it the recognition as the most beautiful zanpakut� in Soul Society. Sode no Shirayuki utilizes ice to attack, each of its three abilities being labeled as "dances" by Rukia. "First dance, white moon" (��舞・月白 some no mai, tsukishiro) denotes a circular area around Rukia's target and freezes everything within the circle from the ground upwards until it reaches the sky. "The next dance, white ripple" (次�舞・白漣 tsugi no mai, hakuren) fires a massive wave of ice from Sode no Shirayuki's blade. "Third dance, white sword" (��舞・白刀 san no mai, shirafune), her final ability reserved only for when her blade is broken, reforges her zanpakut� with ice particles, piercing through any object in its path and freezing anything in the vicinity.
