Tyrfing, Phantom of the Alchemist (Patreon)

taken from the Wiki:

Tyrfing is a "Killer Princess" from the Church of Ragnarok who was guided to this world from the continent of Ragna. She shares her name with her Killium weapon. She's a polite and serious girl, but in combat demonstrates an incredible power and energy that's totally at odds with her usual manner.

A pink haired , very serious and polite "Killer Princess", 🔥
