Asura

Ashura (阿修羅) is one of Xaldin's weapons in Kingdom Hearts 358/2 Days. It is Xigbar's basic weapon, and therefore requires no Gears to be attached to him in order to wield it.

Asura/Ashura is both a recurring Katana weapon and Summon in the  Final Fantasy video game series, as well as a boss in  Final Fantasy IV and  Vagrant Story. Asura is also the name of one of the servers from  Final Fantasy XI.
