Fibble is a coward and spineless and thus has no strength to actually enforce any commands, so Sin does not obey him. In fact the only command Fibble ever seems to get Sin to obey is to make him a strawberry smoothie. As a result, Fibble orders them all the time to drink (to Sin's anger and dismay). He has medium red hair off his shoulders, short sleeved shirt with dark long pants with dark shoes. Fibble was only 19 and fresh into college when he got cursed with Sin.
