Yoshiki and Hikaru learn from Tanaka that the only way to stop impurities from flooding the villages is to close the holes letting them through.
The catch?
Holes can only be closed from the other sideand once a living human crosses over, theres no way back. With that in mind, Hikaru makes a daring proposition: seeing as he isnt human, he can patch the hole and return using his connection with Yoshiki. Meanwhile, Asako and Tanaka try an entirely different tacticconvincing an impurity to do the job for them!
