Natchan

Known as the little girl during the summer (both in this anime, and in Please Teacher!). In this series she is seated on a lifeguard's tower, her dog seated beside her, scanning with binoculars for a boy to fall in love with. She spots Maiku and falls for him. A moment later she sees Karen and Miina, which breaks her heart. She tumbles backward off the tower, dragging her dog by the leash after her.
