Kobato and Osanai made a pact to lead a quiet life as regular students upon entering high school. However, soon after, a handbag mysteriously disappears at the school, and Kobato is asked to help solve the case.
Why don't we go get some 
sweets to celebrate?

per festeggiare l'ammissione?
Que tal algo doce para comemorarmos?
Может, сладкого купим
в честь нашего зачисления?
