Elf Sisters' Miraculous Summer Festival

Elf sisters from another world stumble into a lively human summer festival. Dressed in vibrant yukatas, they point at the fireworks by the riverside. The blooming bursts in the night sky illuminate their bond. Amidst the lantern-lit stalls and joyful crowds, they revel in this one-night adventure. Perhaps these fireworks hold the key to guiding them back home?
