A Comet Approaches! The Earth's Final Night??

Synopsis

The children of the church choir were looking forward to Comet Graham, which approaches Earth once every half-century. To make memories with a friend who's about to move away, they had planned to go observe it at the observatory on the outskirts of town. But the observatory staff, unwilling to have their viewing disturbed, drive the children off. Meimi and Seira join forces to give the children that comet as a gift.
