Ashido Kano

Ashido is shown to be rather serious most of the time, having carried the mental scars created by the deaths of his teammates for many centuries. The very reason Ashido stayed in Hueco Mundo so long was to avenge the deaths of his friends and protect the Human World by killing as many Hollows as he possibly could. He met Rukia and saved her on several occasions, and would have left the forest with her group if he had not been forced to save them from the Menos. Even after several centuries of living alone in Hueco Mundo, Ashido still harbors a sense of sorrow at having lost his companions and visits the site of their death from time to time to pay his respects. He later brings Rukia to this same spot, claiming that it would be nice if his deceased friends could hear the voice of another Shinigami. Hundreds of years ago, Ashido and his unit fought against a large number of Hollows. As Ashido's unit pursued the Hollows, they began to retreat through a Garganta into Hueco Mundo. Ashido and his unit followed the Hollows through the Garganta and ended up in the Forest of Menos. Ashido and his unit knew where they were and continued fighting the Hollows despite this, but the fighting eventually attracted several Menos Grande. The Menos Grande attacked and fired Cero blasts, killing several of Ashido's comrades. The Hollows eventually overwhelmed Ashido's unit and killed all but Ashido and one of his comrades. As Ashido went to face the group of Hollows alone, he left his friend to rest, but a Hollow attacked and fatally wounded his friend. Ashido's friend managed to kill the Hollow, but died soon afterwards. Enraged by his comrade's death, Ashido grabbed the mask of the slain Hollow and killed the remaining Hollows himself. Ashido decided to stay in the Forest of Menos and kill as many Hollows as he could in order to protect the Human World.

Mask Shield: Ashido carries a shield crafted from Hollow masks. The shield has proven to be of great use, for it can withstand and deflect Cero blasts from both Gillian-class and Adjuchas-class Hollows.

Cloak: Ashido wears a fur cloak with many Hollow masks attached to it. The cloak also hold Ashido's Mask Shield when he is not using it.

Mask (Former): Ashido is usually wearing a Hollow mask covering his face. The mask was obtained when Ashido arrived in the Forest of Menos, coming from a Hollow killed by Ashido's last teammate, who was wounded by the Hollow. The mask itself is highly durable, as it was initially used as a shield to deflect various Cero blasts from Gillian-class Menos. It also protected Ashido from harm when he saved Rukia Kuchiki from a lethal blow from an Adjuchas-class Hollow. However, the mask was broken as a result.
