In hope that Akira would see Kazuya's terrified facial expresssion, who's never afraid of any such thing, that he suggests a test of courage.Because they wander in to the forest, Akira never expects such a thing serious that occurs. Though, the additional time they spend within, the more that he realizes something is wrong. And the more that he realizes, that the reality behind the legend is really a real-life nightmare.
