It's obvious that she's the "Princess" in Hell Seether. Due to his commanding princess-like behavior on always commanding other to do their job.
But unlike any normal princess, she's been through hell for 20 years when she's ran away from her family's military background to study abroad and to forge her own path without her family's burden.
But once she secretly joined the Hell Seether to prove her skill, she's surprised to herself that she could eradicate the entire 30 North Korean elite juggernaut in just one shot on each head.
Maybe she's more comfortable on living outside of the comfort zone than living in a comfort zone that make her uncomfortable.
PS: I changed her iris. Slightly inspired by Flandre Scarlet from Touhou.
