Kibito
is from the God Realm and is the bodyguard of Shin. Together with Shin he has arrived on Earth hoping to save the universe. While on Earth something happened and he was permanently fused together with Shin and is now know as Kibito-Shin.
While in Okinawa he enjoyed a small stroll around the area of Fukuchi Dam. He has hidden a cache near the beginning of the awesome trail system that spreads for miles in the nearby mountains and forest. Begin your hike at " Nuthin Better to Do #5: Mongoose Beware" and walk up to hill to a tower-like structure. The cache is in this area.
Inside the logbook of Kibito you will find half the coords to find "Kibito-Shin".
And if your feeling adventurous and you have a few spare hours, please follow the hiking trail from here and get some great caches in the area.
