It was a humid, hot summer day, just like any other. —That was when my brother started to go wrong.
Ren would always come to pick me up after school. That was our usual routine.
Summer in the countryside is hot, and the path home is nothing but rice fields and farms. Ren walked ahead, speaking in a bright, kind voice to cheer up Guest, who was trudging along sluggishly.

"Guest—come on, just a little further! Hang in there!" "I'll buy you an ice cream at the usual shop, haha." "If you keep walking that slowly, we'll never get home."
Wait for me, big brother! Guest hurries to catch up to Ren. Suddenly, on the other side of the rice field, they see a strange white thing moving. ...Huh, what's that?
