Ever since Rantaro Amami had lost all of his sisters around the world, he continues his travels, hoping to reunite with them someday. Even though he hasn’t made any progress yet, he was able to experience many different cultures, learn folklore from other regions of the world, and even help people along the way.

One day, Rantaro came across what looked to be a forgotten artifact while he was setting up shelter, an ancient arrowhead. The next morning he travelled to the nearest village and did his usual routine of asking around for his sisters, but also about the arrowhead.

Rantaro was eventually directed to a large building riddled with foliage and weeds on its exterior, this was apparently the home of Korekiyo Shinguji, who might be able to identify the arrowhead. Rantaro waited for quite a while to even enter the home, knocking on the door and waiting several minutes, even leaving to return at a later time, but Korekiyo never answered the door. Korekiyo was clearly inside judging from the lights through the tarnished windows, so Rantaro just attempted to open the door, which was unlocked.

“Hello? Anyone home?” Rantaro called out into the darkness, the entrance appeared to be meant for visiting guests given all the coat racks which were adorned with cobwebs, Rantaro ran a finger over the tip of the arrowhead as he watched for any sign of Korekiyo.
