Sakura Capsule  

サクラカプセル, Sakura Capusule

In a Tokyo neighborhood on the outskirts, there was a small park where six girls played together since childhood. However, when they were in fourth grade, they had to attend different schools. Despite making a vow to bury a time capsule, they couldn't fulfill it and eventually went their separate ways. Four years later, as adults with their own struggles, they reunited. Although each faced unique challenges, the days passed until one day, an unexpected event occurred.
