Ferris Wheel and the World's End

Rigel was visiting his comatose friend, Bella, at the hospital. He fell asleep while reading her notes, and when he opened his eyes, he found himself at an amusement park called Neverland. With Mira, a mysterious little girl, he had to collect stamps from [cursed rides] to bring Bella back with him to the waking world.
