Mr.2 is a legendary spy for MNM, a private intelligence organization operating in regions where direct Korean intervention is prohibited. During a secret mission in the Middle East, Mr.2 is captured and subsequently abandoned by MNM. A decade later, a doctor from the intelligence agency goes missing, and an explosion during the rescue effort points to an internal culprit. With MNM's future at stake, the team leader is instructed to contact Mystari, who is secretly the former agent Mr.2. Despite his reputation, Mystari is unexpectedly light-hearted.
