Fay D. Flourite – Tsubasa: RESERVoir CHRoNiCLE – _Images

Fai D. Flourite (ファイ・Ｄ・フローライト) It is stated in the manga that he is named after the stone fluorite. It was later revealed that his real name is Yui. In the anime adaptation of the manga, he is voiced by Daisuke Namikawa in Japanese and Vic Mignogna in English.

Fai is first shown sealing away King Ashura of Celes Country at the bottom of a pool. He transforms his creation Chii (originally from Chobits) into a net-like shield, instructing her to alert him if King Ashura should awake. He then uses his magic to transport himself through dimensions, to the shop of the Dimension Witch, Yuuko. Out of his traveling companions, Fai's motives for joining the group are the least clear. He is the only one to arrive at Yuuko's Shop purposefully, by use of his own means. His wish is to never return to Celes country, but as the price for this would have been too great, so he travels worlds with the group instead. He fears King Ashura’s awakening, believing King Ashura would chase him through different worlds.
