Mysterious transfer student

Encountering a particularly blustery morning, Yuu remarks that something is sure to happen that day as she begins her school commute; sure enough, Yuu encounters a boy named Mamoru Hidaka that annoys her classmates with his insistence on divining the wind and repulsing all student attempts to enforce the school rules as he makes a hasty retreat. Posi and Nega set off to search for Mamoru who detects that they are not ordinary cats before Yuu comes to retrieve them; Mamoru accompanies Yuu back to her home as he explains his prologue in his hometown on Hokkaido and that he is having trouble adapting to Tokyo's urban environment over crepes -- particularly Creamy Mami. Toshio and Midori enjoying a Creamy Mami concert before they notice Mamoru's absence ultimately becomes the forum for Mamoru's perceptiveness of the local songbird species and proficiency in carpentry to make its advent along with Yuu having a new friend -- especially when she wakes up to the snowy morning Mamoru accurately predicted.
