In "Ayashiki Raihousha," a mysterious visitor appears in front of Tanuma. Nearly every day, the visitor visits Tanuma, talks to him a little, and then leaves. Natsume, who knows the visitor is a youkai, worries for Tanuma, but Tanuma enjoys these exchanges with the youkai. The youkai means no harm, but Tanuma's health slowly starts to deteriorate.
