Miyagawa Hao has just come to Tokyo from Osaka. To relieve her of a headache, a passing bishounen offers her a packet, which was suppose to have a pill inside.

Legend has it that if you wear the same pajamas as the one you love, you will be transported to him for a short period of time. Misaki Aguri decides to try this out with the person she has a crush on, Isozaki. She never quite gets where she wants to be.

4. Koori Musume wa Otoshigoro (氷娘はお年頃)

Kahyouzan Koori runs into Kazama Shuuhen at the beach (quite literally) and falls in love with him. Her grandmother does not approve of this relationship, and makes a deal with the couple. If she can break a string tied around their fingers, Kazama must leave Kahyouzan. Unfortunately for Kazama, the Koori family has a special ability that he must defend himself against.
