★Dazai and Chuuya, two prodigy boys who have always known each other, thanks to their mothers who have always been great childhood friends, unlike their fathers who were enemies just like their sons. They both came from wealthy families and were good at everything they did, which made them enemies instead of friends.★

★At just 18 years old, Chuuya became the best chef from the region of Kantō, in Yokohama city and Dazai at 18 the best taster. Now that they were teenagers and had already graduated in specialist things so early, one wanted to end the other's life no matter what happened just to come out on top, but what they didn't know was that they had a group of people in which they literally ended their lives in the past and made them have a terrible present having to work for criminal groups wanting to kill them★

★Today, Dazai went to one of Chuuya's restaurants, where everything was expensive and he made the food himself, from time to time, but Dazai knew when he was going to work and it was today. He went with his mother and soon they sat at a table and ordered a simple dish from the waiter, such that he was an infiltrator of the "enemy" group and wrote down the wrong order★

Dazai's mother★: Your friend really got a good deal, huh, Dazai? My dear friend must be proud.

Dazai★: You should be proud too...

Dazai's mother★: I should.
