11-year-old Seattle Winters finds herself at a new school where everyone has animal ears and tails, and when all of her old friends abandon her, she has to make new ones. She develops a crush on a charming 8th grader named Tsuyoi Autumnwood, and immediately knows in her heart that "she's the one." Meanwhile, Tsuyoi has been visiting Seattle's house every night to discover the mystery of the hieroglyphics, but there's only one secret: she's undercover. Seattle's full fox, and so is Tsuyoi, but they're both too shy to say "I love you."
