Hassan of Serenity

The Hassan of Serenity's most notable trait is her Noble Phantasm, Zabaniya: Delusional Poison Body. Her body resists every single poison, while simultaneously, it is a lump of poison too. Not only her nails, but even her skin and bodily fluids would act as deadly poison as well. Obedient, and lacking self-assertion. In her youth, she was merely a girl who conducted assassinations very mechanically. Even now where she became a Heroic Spirit, those characteristics have not changed as much.
