Ojamajo Doremi 16

"Harukaze Doremi, high school freshman! Today will be an important reunion. Hazuki-chan, Ai-chan and all of my old classmates should've shown up, but there's no one here... What happened? And when I go to that nostalgic place, the Maho-dou is there. What is this premonition? Will I become a witch apprentice again? Can I become one again? What should I do?"
