With one marriage edict, two people with mutual hostility are forced to marry and live under the same roof. Yet after these long days together, they come to the realization that this fellow is not truly devoid of any saving grace/unattainable and high out of reach.

Liola—the best assassin in his world—has vowed to kill no more. He was being chased by an assassination organization when he accidentally dropped into a parallel universe: through a dimensional gate and into poor teenager Kaiser’s apartment. Instead of going to the government shelter for lost dimensional travelers, Liola and Kaiser wind up going to school together.

Liola has been trying his best to live the life of an ordinary person, but after certain things happen one after the other, he begins to realize that being an ordinary person could be harder than being an assassin.

“Hey, have you ever heard of the lunatic roaming around the tower?”“Are you kidding me? Who haven't heard of him yet!?”“Hey hey, are you talking about... that person?”Interesting news travels even faster than light, especially regarding the mysterious figure that everyone in the Ethereal Tower is curious about, the lunatic ascender whom thoughts and deeds are so off-place that even the greatest among them just couldn't grasp his intent, almost as if he is ascending a completely different tower than them.While everyone in the tower talks about the lunatic who lurks on each tower's floor more than he is supposed to, the person they are talking about just goes on his merry way to collecting treasures he wants, and while the world is talking about him.“Come on, give me some luck, maybe roll the hundred times multiplier again...”He's sitting while rubbing his palm together, gambling on something that will make everyone faint.
