Origins: Gokukoku no Brynhildr (Kiwaguro no Brynhildr/Brynhildr In The Darkness)
Classification: Human, "Magician" (Human-Alien symbiote hybrid)
Threat level: God-
Physical strength: At least town+ (casually kicked her sister several kilometers making her fly through a few buildings in the path)
Destructive capacity: At least country+, possibly planet+ (can create MBH's (micro black holes) of up to kilometers in size, obviously the MBH's ignore durability up to a certain extent)
Durability: City block+ (Valkyrie survived an attack of this level and shes far weaker than Kuroneko), at least city+ via barriers (Valkyrie generated enough anti-matter to overkill Japan to try to corner Kuroneko)
Speed: Massively hypersonic+ (uses a form of teleportation in which her body basically moves as energy, she was fast enough to react an attack that crossed kilometers in a few instants and then outspeed and intercept it before it moved a few centimeters), faster than light processing (she can calculate and control things such as particles moving at near lightspeed and black holes and there gravity)
Intelligence: Super genius. Despite having absolute no education she beat Ryouta Murakami's high school exam results after a single school year of education despite Ryouta himself being a genius. As mentioned above she can process information at incredible speeds and she is obviously a genius combatant (S+ class "magician) superior to even Valkyrie.
Stamina: Low. Can only fight for a few minutes before running out of capacity to use magic, her body does however have decent endurance to things such as pain and thus could continue fighting as a normal human even if her magic power runs out.
