Porphy no Nagai Tabi Episode 52

Porfy, his younger sister Mina, and their parents live a humble but happy life in the Grecian countryside. They've just started running a gas station, much to Porphy's joy, and it seems like only good things are in store for their future. However, a huge earthquake changes all that, leaving Porfy without a home or a family -- sans Mina, who seems to have disappeared in the commotion. Now, Porfy is determined to find his sister and be able to live together happily again.
