She is 150cm tall, weighs 40kg, has an A-cup chest, and is a chuunibyou patient. She calls herself the wielder of the Tyrant's Eye. Her eyes are cyan, but she wears a gold-colored contact lens in her right eye and calls it the Tyrant's Eye. She also wears a white eyepatch over her right eye for the same reason. She wraps bandages around her left arm as a chuunibyou prop. She has an ahoge. She is very boastful. Despite being a chuunibyou patient, she isn't bullied; rather, there are people around her who talk to her. She has bangs that cover half of her eyes, chin-length short hair, and a side ponytail tied with a yellow ribbon on the left side. Her hair is a deep dark violet. Her sideburns reach down to her jawline, and the back of her hair just covers the nape of her neck. She suffers from chuunibyou and refers to herself as a wielder of dark powers. Outside of her persona, she has a somewhat innocent side. She has almost no friends, though there are kids who talk to her occasionally. Her athletic ability is zero. She uses a chuunibyou manner of speech, but her normal way of speaking comes out when she is flustered. Even when facing something for the first time or something she can't do, she bluffs and says she can do it. She hates tomatoes, making the excuse that red fruits lower her magical power. She is a huge idiot. Being clumsy, she trips easily, often loses her wallet or belongings, and even frequently messes up her own chuunibyou settings. She can't cook, so she always eats haphazardly, often consuming convenience store bento boxes. She continues to act and speak in a four-dimensional manner. She is shy and takes a chuunibyou-style aggressive stance toward people she meets for the first time. Being a loner, she feels lonely. Her father passed away, and losing him at a young age was the catalyst for her falling into the world of chuunibyou and failing to accept reality. She keeps a cat named Chimera, equipped with a 'wing garment.' Even though she is no longer a middle schooler, she is still deep in her chuunibyou phase. When she enters a combat stance in mid-air, she uses the umbrella she carries as a weapon. She uses it under the name Schwarz Sechs Prototype MK-II in accordance with the settings related to the Tyrant's Eye. She imagines herself wielding it like a sword or spear. She uses chuunibyou skill names like Dark Matter Blaze. She carries deep wounds inside. She is financially poor. Though hidden by her incomprehensible behavior, she is objectively considered a beautiful girl, though she doesn't realize it herself. She is so immersed in her chuunibyou that she doesn't perceive it as such and truly believes in her powers. Her youthful voice and way of speaking don't quite match. She is often lightly bopped by those around her trying to reason with her, and every time, she makes a sound like "Augh!" and gets scared, causing her speech to return to normal. It can be said she has no tolerance for pain. Whenever her chuunibyou gets too intense, she snaps out of it if her forehead is lightly flicked. She is less prone to embarrassment than others and doesn't particularly care about things like indirect kisses. When her chuunibyou manifests, she doesn't harm anyone and only uses it to show off her abilities. She rarely initiates conversation or shows interest in others. She is more cowardly than she looks, so she almost never picks fights. Her chuunibyou persona slips off more often than one might think.
