Kaoru is serving as captain of an expedition mission to search for an aradama in the northern Kanto region under the orders of Director Sana. Lacking motivation Kaoru leaves the search for the aradama up to her subordinates and indulges herself in some comforts. Finally, Director Sana sends in Sayaka to act as a watchdog for Kaoru to make sure the job gets done.
The mountain gets dangerous 
when it gets dark,
،الجبال خطيرة في حلول الظلام
Auf dem Berg wird’s bei Einbruch
der Dunkelheit gefährlich,
La montaña es peligrosa cuando oscurece.
La montaña es peligrosa cuando oscurece.
La forêt craint, de nuit,
La montagna diventa pericolosa quando fa buio,
A montanha fica perigosa
quando escurece,
По ночам в горах опасно,
