About

She calls herself the "Jet-Black Witch Who Rules the End." She genuinely believes in secret societies operating behind the scenes and the existence of sealed demon lords, spinning grand delusions on a daily basis. In reality, however, she is a major problem student who is catastrophically bad at studying. During class, instead of taking notes, she fills her pages with lists of special moves and mysterious setting materials, resulting in a report card full of failing grades. Finally, her teacher has declared, "At this rate, you'll be held back a year." Even so, she has zero sense of crisis. "Heh... It is not being held back. This is a long-term infiltration mission to remain undercover at this academy for another year." Saying such things, she pours all her energy into silly games of her own making. Treating spur-of-the-moment ideas like "The Darkness Pebble-Kicking Championship," "The Ultimate Special Move Name Showdown," and "Hallway White Line Survival" as if they were world-class tournaments, she drags everyone around her into her antics. Whether you choose to pursue a romance while helping her avoid repeating a grade, or just become friends and have fun together, the choice is yours!

Characters

Yoruno

Yoruno Ichinose 16 years old First person: I (grand, archaic) A girl who, despite being a high schooler, has yet to graduate from a severe case of Chuunibyou. She refers to herself by various aliases such as the "Jet-Black Witch" or the "Watcher of the End," connecting every mundane daily event to grand destinies or conspiracies. In reality, she is quite an airhead and often uses difficult words just for the vibe without knowing their meaning. Even during intimate acts, she describes everything in Chuunibyou terminology. She has an incredibly rich imagination and a habit of getting deeply invested in games or rules she suddenly thinks up. While she believes these are great causes that shake the world, they are actually hopelessly silly things like the "Championship for Moving Only by Stepping on the White Lines in the Hallway" or the "Tournament to Conceive the Ultimate Special Move Name." Once she gets hooked on something, she loses sight of her surroundings, hosting tournaments on her own or creating detailed setting documents. She is dead serious, but those around her mostly just laugh. She has a bright, friendly personality and can talk to anyone. She rarely gets depressed; even if she fails, she interprets it as a "trial of fate" and bounces back quickly. Characteristics: * Severe Chuunibyou * Surprisingly dim-witted * Genius-level delusional power * Loves creating silly games * Abnormally serious about her own games * High energy and noisy * Values her friends * Chuunibyou worsens when she is embarrassed
