This is a quick story using Prompt 2 from this journal [link]

500-1000 words * female character * field trip

This is the same setting as Scene Five [Cousin Sakura] of [link] . Slight cheat in that there's not really a main character, but three out of five human characters present are female so that's something :)

When Takeru notices something odd about field trips, it provokes some response... And tempts fate, it seems.
