I woke up in the middle of what seem to be hospital room with no memories of whereabout I am or who I am. The only one I know of is that I got a strange metal helment on my head. I pushed myself off from the floor that I was laying on and scanned around the room, totally empty. Nothing in it, not even a window or a door. First thing that came to my mind was a fear, a fear of trapped for life. I jumped onto my feet and ran around, trying to find a way out until I spotted a black outline on the wall that shaped none other than door. I rushed there and try to get my fingers into the crack only to find that it's a wall as well. I sighed and turned around until I heard a metal clashing against each other to turn around to see the only thing in whole world that would struck me as a fear that unbareable to hold on to it. 

It was Yaku.
