Adventure of a Lifetime

"There’s something I need to get back—something precious that sank into the ocean years ago." Set on Japan’s World Heritage-listed Ogasawara Islands, this story follows Hiroki Mizuno as he returns after four years away. He comes back during summer vacation to help his grandmother run her shop, but the trip quickly turns into something more. On the ferry to the island, Hiroki meets Emily, a beautiful blonde girl who has run away from home. She’s determined to recover "sunken treasure"—and Hiroki’s childhood friend Chisa offers a clue: one local shipwreck is known as the “Ghost Ship.” Legend says the treasure Emily seeks is hidden in a shipwreck that vanishes whenever a storm hits. Spend the summer on a tropical island with Emily and Chisa, diving beneath the waves and chasing adventure. Their destination is the “Ghost Ship,” somewhere just beyond the horizon—past where the sky meets the sea.
