Rusty is a member of the 9th Regiment of Lambert's Regnant Knights. Rusty plays the role of an elder brother for the other members. He has an aloof personality and can often be found enjoying flirting, reading, and going to hot springs. However, behind his carefree personality lies a troubled soul and Rusty can be serious, if not somber, should the occasion rise. He is shown to lose his temper under immense pressure and often responds violently by lashing out both physically and verbally.
