Tabi to Michizure

A girl named Tabi takes a train to visit her childhood friend, Kou-chan, in a town where she meets Officer Nishimura and a lively young man named Yukita. They are surprised to see her arrive by train, as it is an unfamiliar route. Upon arrival, Tabi realizes the town is unusual. Some roads in the town randomly collapse into deep pits, seemingly attempting to swallow people. Each day, the town resets, replaying the same events, and the residents remain unaware of the strange occurrences, forgetting everything each time. Tabi, Yukita, and Nishimura are the only ones who remember.
