Houkago Usamimi Girl

After the final bell rings, an ordinary high school girl suddenly sprouts a pair of fluffy rabbit ears. At first, she thinks it is a prank or a dream, but the ears remain stubbornly attached no matter what she does. Panic sets in as she realizes this is real. She tries to hide them with a hood or a hat, but they keep poking out, drawing curious glances from classmates and teachers. At home, her family is just as shocked as she is. The next day, she discovers the ears react to her emotions, twitching and drooping on their own. Worse, a mysterious boy in her class seems to know something about her condition, and his knowing smile deepens her confusion. With no one else to turn to, she must decide whether to trust him or find another way to reverse the transformation. As she spends more time with him, she uncovers hints that her condition is linked to a secret beyond her own body, and that the rabbit ears might be the key to a much larger mystery. But every answer brings new questions, and she realizes her after-school life will never be the same again.
