Interrogation seemed to work, as he was able to get a slight bit more information for pressing on that matter. Reiki didn't really look at the door he entered through when approaching, so any form of detail he might have seen may be gone. He at least seemed consistent with his words about not having the key. There were many things that could disperse, but he doubts that he would be put in a genjutsu as of currently. So clones, at least that was all Reiki knew. It was an assumption, but it was likely that this one didn't have a physical key of some sort.
The door? Hm... That might satisfy Reiki's curiosity if he could note something. What realization could he obtain from the door? So he would back away from the man and leave him alone after hearing that. It was obvious once he reached the door. And the door's location was still a mystery. Huh... Well climbing up that wall did not look like a door. And if it wasn't an exit, it didn't look like something nice either. Chance wasn't something he could play with. But in that case, the only way to go was back.
Oh, and the bonus of knowing that if this man was telling the truth, the other one was telling a lie. Sure, that sounded nice. But there were four human pieces. Say one of them was Reiki, then that meant there was still one human out on the loose. Or maybe that was a lie that the grid wants him to believe. Eight forks before the end stuck out to him though... Perhaps this man was telling the truth. Could Reiki be punished for trying to make the climb?
Wait a second... What if the maze CONTINUED by climbing up? The man said that it wasn't the exit, but perhaps it was a continuation of the maze! Maybe maybe maybe...
"I guess..." He would walk back over. It just wasn't the exit, it just wasn't the exit... And if Reiki had to tell himself that a million times to give himself the courage to go up, then so be it.
Caution was taken when he did so, but he had the experience of climbing back in his village when he did this. Mountains gave him the experience, so this shouldn't be as bad as it could be. A narrow passageway, it was going to be difficult for him to do this. This may be a deadly game of chance he was playing with by doing this, but it might be the continuation as well. So he would begin to climb up, slowly... Carefully... And yet cautiously. His eyes saw far with clear details, they couldn't be misleading him here, right? And if they did... Damn it... Well, the first sign of danger that they saw would make him let go the surface he climbed.
SA in effect:
Enhanced Eyesight
The user's eyesight is heavily enhanced, even without the use of the Tennogan. The smallest details could be observed as if it were in front of the user should the distance between them not exceed 30 meters. Peripheral vision also seems as clear as if it were the main sight of focus.
