Arien

Arien (あり得, Arien) is a unique Soul that formerly resided in Soul Society. Upon being persecuted by the Gotei 13 for his abilities, he ran away. Through what is thought to be pure chance, he opened a Senkaimon, bypassed the Dangai Precipice World, and fell into the human world. Therefore, he is currently a Ryoka in the Soul Society, despite his young age. He encountered Daisuke Masanori in w:c:bleach:Karakura Town in his first night; since then, he was given the name "Arien", as well as the moniker The Impossible Boy (無理少年 Muri Shōnen).

Behind the Scenes

 * Arien's name is a shortened version of the saying, Arienai (有り得ない), in Japanese, this is generally a way to express something that is "impossible", which is a core theme behind Arien's name.
 * Interestingly, and quite coincidentally, Arien's name sounds quite similar to Aryan; an English language loanword derived from the Sanskrit ārya, meaning "noble." However, the term also denotes to a master race of Nazi Germany, and a term for the Indo-European language group. Daisuke comments on Arien's noble nature when dealing with most matters, indicating that this connection isn't purely coincidental.
