Sadira

Sadira is a ruthless killer who delights in seeing her targets in pain, showing a clear sadistic streak in the way she taunts them in her native Thai tongue before each battle. She is easily influenced by fame and fortune, striking a deal with Ultratech in order to make the Red Eyes of Rylai the most powerful clan of assassins in the world. She also shows much dishonesty and cunning, having claimed her position in the Red Eyes by murdering her mentor and taking her place - she knows when to stay in line though, as during her service with Ultratech she was very loyal to ARIA and would undertake any order, knowing she was well out of her league with the megacorporation. However, after her ill-fated encounters with Glacius and Hisako she was discharged from ARIA's service and beaten to a pulp by her former comrade, Cinder. Frustrated and seeking revenge, she has been swayed by Gargos' temptations before and has trouble keeping control of her hidden temper.

She first encountered Ace and Spirit Force in Medina and again in Valentia where she was defeated by Sectonia twice.
