The half-brothers, the player, and their supernatural-hunting friends take 23 days of Japanese vacation to explore with Scott Jones' best friend, Katie Bell. Arriving in Japan, thanks to Annabelle's infinite wealth from her late father, the children and the hunters embark on an adventure, hunting down mythical creatures, making friends with them, and solving mysteries. Also, they must help Chief Jacob Arrow and his son Lloyd cope with their grievance, and at the same time, the boys are now suddenly reunited with their great-uncle Captain Read who hasn't seen them since eight months ago while they befriended an amnesiac homeless feral girl with a strong love for animals and nature whom they instantly bond with as they were unaware the dark secret she had.
