Neko Kuroha

Neko Kuroha is the lead heroine of Gokukoku no Brynhildr. She is a rank B Magician that escapes at the beginning of the story. She is also the Vice President of the Astronomy Club, and one of Ryouta's main love interests. Her research number is 7620.

Appearance and Personality
Neko is a beautiful young girl that has dark blue hair, violet colored eyes, a 3-dot birth mark that forms a triangle that is on her upper-left breast. She wears a white dress with a black collar, decorated with white lines, a purple bow on her chest, black arm sleeves, and black stockings. At times, she puts on a mask to conceal her face.

Neko is very cheerful and somewhat clueless (mostly due to her losing some of her memories every time she uses her powers). When she is alone she enjoys singing about the people she's saved and helping people, thinking of herself as a superhero of sorts. When around others, she is very quiet and doesn't speak unless when spoken to, preferring to avoid conflict. However, when her friends are in danger or have been harmed she gives off a very threatening aura, such as when she thought Ryouta or Kazumi were bullying Kana. She often displays signs of jealousy when Ryouta's relationship with Kazumi (or other women) is called into question, unintentionally using her destructive powers in order to release her frustration; breaking a school window with her magic when Ryouta asked that Kazumi accompany him in the city and breaking several tree branches when she thought they went on a date and kissed. She refers the other witches with the suffix "-chan", even those who are her enemies, such as Kikako.

Powers and Abilities
Neko is capable of destructively influencing objects that are in her vision range. She first demonstrates this power when she punctures a hole in the school's swimming pool in order to save a student. Later, she splits a boulder clean in half in order to save Ryouta Murakami. Her powers can be used in a variety of different ways, from outright destroying specific objects to cloaking it around herself in order to deflect bullets. However, the use of her powers cause her to lose some of her memories. They are typically trivial memories, but she occasionally loses important memories. Her memories are full of holes because of this, and most of her childhood memories have been lost.

In reality, Neko was the previous Valkyria, an rank SSS magician, and her full potential is released when Ryouta presses the third button on her Harnessed, returning her memories and granting her with a variety of additional powers:
 * Telekinesis
 * Barrier magic
 * Enhanced physical strength
 * Self-targeted teleportation
 * Micro black holes
 * Regeneration

Trivia

 * Her name is very close to the word "kuroneko," meaning "black cat."
 * In Chapter 96, it is implied that Kuroneko and Neko are different pesonalities for *Kuroneko did not follow why Ryouta called her Kuroha when he always called her *Kuroneko in their childhood. Another implication is when Kuroneko called out her sister, Valkyria, on the damage to the small town they were in despite her knowing it previous to 'regaining' her memories.
 * ==== SPOILER ALERT : She kissed Murakami two times on the lips.====
 * It is proved that she is actually smarter than Ryouta Murakami.
