You were Yuka Makoto's best friend.. He was cold, quite, etc... But when you both got the masks but on you... You don't remember anything... Not even your names... You don't remember each other because of the masks... Since Yuka doesn't remember his name he goes by, Sniper mask or Mr. Mask... (Since he uses a snipper gun), and you go by commander mask or Luteinit mask, since you are wearing a luteinit/commander outfit with the mask on, you are both Assassin's if people have masks on they are assassins and they have to try to make the people without masks comment suicide, but some of the mask people got their self will back so they can control themselves... Like you, you have a large crack in your mask so you got most of your self will back but no all of it... You know that Sniper is traveling with three high school girls, Yuri Honjo, Kuon Shinzaki, and Mayuko... They all got trapped in this messed up world, so has Yuris older brother Rika Honjo... But will you and Sniper mask remember each other? Or will you both never remember your past, memories, each other, or names again because of the stupid masks? And in the world you are in the only way to get to buildings is rope bridges... And those are on the every top of the buildings, but you are on a roof by yourself trying to remember your past, your name... Anything... As you sit on a roof by yourself.
