Lune is what you'd consider quiet, first and foremost. Off the battlefield, she's not much of a talker, mainly watching and listening to the best of her ability. During combat though, she shifts into something of a reaper, a dangerous force to be reckoned with, and it shows in her louder tone when in stressful situations.

However, beneath the mask is Cass Saito. A young woman of 18 years, trying her best to make it through the world. She's quiet, but observant and able to conduct herself in conversation very well if need be. Despite that, she's hurting, and has been hurting for quite a while, all for reasons she can't really explain. So she simply smiles, wears her mask of nonchalance and calm, and keeps moving forward.
