Kaeru Batake DE Tsukamaete☆

It all began when they broke that shrine. Sugano Fuu is a first-year student at Tsukiyado High. One day, along with her senior Norizuki and classmate Hirose, she decided to investigate the 'Seven Mysteries of Tsukiyado' for their club. It wasn't a thrilling topic—they were just killing time. 'Hey, there's a weird shrine at school, right? Let's check it out.' So, in that casual spirit, they went. At the shrine, Hamura and Kuga were already there. They weren't on good terms; they were practically strangers. After a quick hello, the investigation began. The shrine was old and locked, though not bolted. When they pried at the rusty doors, they crumbled. Inside the debris, they spotted 'something.' As they stared, smoke erupted. 'Is it poison gas?!' They hurled the object away, but the smoke still engulfed them. Before they knew it, they had turned into frogs.
