Mercenary Enrollment Manga tells the everyday life of a high school student, a former soldier, in peacetime. Ijin was in a plane crash when he was 9 years old but managed to survive. For the next 10 years, he served as a mercenary in hot spots and became a powerful warrior. He single-handedly rescued entire squads from difficult situations. But his commander thought about what he needed to learn. He told him about life and how to behave in a peaceful society, about how guys have fun after school. His commander warned him to avoid fights because he feared for the lives of his opponents.
He arrived in his hometown, with only his grandfather and younger sister left in the family. He went to the same school she goes to. But on his first day, he had to get into a fight with several high school students after school. They thought he looked at them the wrong way. Before they knew it, he had scattered them. The next day he finds out that her classmates are bullying his sister. The congressman’s daughter and son are the worst kinds of scoundrels, terrifying the boys and teachers. The congressman’s daughter brutally beats Dayun.
The girl does not tell the truth about her injuries to her brother for fear of being beaten. But he immediately understands what the matter is. He punishes the abusers by warning them to stay away from Dayun. And they still can’t understand how he alone could defeat everyone. The congressman’s family sends mercenaries with bats to reprisal Ejin. But they immediately realize that the guy has combat experience after he’s taken them out.
