A member of the Ptolemaic Army, Sisilia uses her signature trumpet to motivate her fellow comrades to victory. Veronica seems to have influenced her decision into joining the Army, though she doesn't feel guilty about it. She rides alongside her comrades on the battlefield on her bike. It is assumed that she is not old enough to use a motorcycle. Like Rumi and Madoka, Sisilia is a supply officer rather than a front-line combatant. If the battlefield becomes too dangerous for her, she will run away.
