"Do I deserve this?" "Am I worthy of this?"

So irrelevant. Do you want it?

Schwarz is one of two Stygian that were created when an ancient Stygian crumbled and fragmented through time and obscurity. Originally reduced to scattered fragments across the Nightmare Realm, his other half's efforts have enabled him to take an independent Stygian form. 

A coy and unperturbed person, he prefers to observe instead of taking on an active role. Unlike Weiss, his main goals in life is to amuse himself, though what exactly he considers amusing is a secret to all, even his soulmate does not quite know. He follows his own whims and interests, often dragging Weiss along in his pursuit of entertainment. While he doesn't mind meeting new people, he tries to keep his distance from them and avoids getting tangled up in other Kingdoms' politics.

Usually, he appears in his Betta form or human avatar form. He keeps his true power and Void form hidden, so that he remains as an unassuming presence in others' minds.
