Narumi is a second-year student at Asanoha Gakuen. One day, he headed to the Garden Club room to return something left behind by his classmate Kazane, but he inadvertently stepped on a magic circle that was drawn on the floor and summoned the spring spirit Haruharu. Since he had now found out that the Garden Club was actually a secret gathering for witches at the school, he was pressured to join the club to keep their secret. It’s the start of their time together which is slightly magical and warm like the spring sunlight.
