A group of prodigious students known as the GREAT 7 built an artificial haven called Nanae Island, a bustling enclave where scholars dominate daily life. Twelve years later the island thrives as a utopia for learning, but its peace is shattered when newcomer Jugo Yama discovers the lingering spirit of Nanana Ryugajo, the island’s enigmatic founder who was slain a decade ago.

Forced into an uneasy partnership, Jugo embarks on a city‑wide scavenger hunt, decoding ancient riddles and confronting rival minds to uncover Nanana’s legendary collection of hidden treasures. The series blends witty banter, supernatural intrigue, and clever puzzle‑solving, offering a fresh twist on treasure‑hunt adventures while exploring themes of ambition, friendship, and the cost of idealism.
