Synopsis
Jogasaki, a 5th grade girl who lives in the neighborhood, is a girl who invites her to go to the sea to see whales from the morning. She is a high school student who goes to the sea with her as she tells her. I don't think she's 11 and 17 years old, romance. The usual summer Wednesday we spend together. I wish these calm days would continue forever.

When I woke up on a summer morning, I organized information in front of the mirror as usual. "Yuki Umino, 17 years old, female gender, 2nd grade C group, parents are alive ──" I brushed my hair on my face and switched to me. Check the day of the week and it's Wednesday. Well, let's do our best for about three days this time as well.

And Mr. Shirogasaki declares. "I want to destroy this world." In a closed seaside town, I and she meet today as well.
