“Munehisa Iwai is the owner of the airsoft shop, "Untouchable" in Shibuya. When the protagonist asks him about the "real" firearms, Iwai shows interest in his motive, says he dislikes the police and offers to supply the real stuff in exchange for the protagonist assisting him in shady activities. He is responsible for the selling of weaponry used by the party, Iwai grew up with a single mother who lived a self-destructive lifestyle, and the lack of a loving family led him to quickly join the yakuza. Not wanting his son to suffer the way he did as a child, he was forced back into civilian life and runs Untouchable to support him.” - Persona 5 Wiki
