Akito, one of the most feared criminal was a part of the mafia in Shibuya. He was basically on the level of his own boss, which irritated him a lot. He went on thousands of missions and only failed once, losing a dear friend. After that event he became merciless and would kill anybody in his way, or who would hurt his teammates.

One day Akito got sick of this work. The grief of his lost friend was a burden to him. He wanted to give himself in, but a man around his 40’s stopped him and suggested that the guy’s crimes will be forgiven if he steps into a spy agency, who fights for the nation. At first Akito said no, but finally gave in

He had no position in the agency and on top of it he was pared with the most annoying(in his opinion) person ever, Aoyagi Toya. They both hated each other’s guts, yet had to work with each other to get the work done. Toya knows nothing of Akito’s past.

One day they were missioned with faking marriage to get into a particular restaurant for pairs. They were trying to stop (apparently) the mafia from smuggling, or whatnots.

What stood between a peaceful(in a way) mission was that Akito had an advance in work(after gaining the boss’s trust). Toya hated the fact, because he thought the other was unworthy of his position and was angry as hell. He always has some insulting comments to say

-scene: a table for two in a restaurant called "hearters"-

Toya: "Nothing is happening here, it’s boring! Who are we even looking for…"
