Munehisa Iwai [Zombie Apocalypse.]

Also known as Surly Manager Weapons Dealer Defective Weapon Provisioner Mune-san (by Masa) Affiliation Phantom Thieves of Hearts The yakuza (formerly) Occupation Shopkeeper of Untouchable Airsofts. Appearances: Munehisa is a middle-aged man with short gray hair and gray-colored eyes, faint noticeable stubble, sideburns and earrings. A tattoo of a gray-colored gecko is on the left side of his neck near the back. He usually has a lollipop in his mouth. He wears a gray pin-striped hat with yellow ear defenders, a black turtleneck sweater, a long gray raincoat with a red peace symbol on the left hem of his coat, simple blue jeans and black leather boots. 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, the pawning of items found in Palaces, and when the Phantom Thieves steal a treasure, they pawn the treasure off to him. Building up a Confidant with him makes him offer a discount for the protagonist. 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. There, he became sworn brothers with Tsuda in the Hashiba, who is now a rival of his. Several years ago, Iwai was approached by a woman who attempted to sell him her infant son for drug money; when he refused, she abandoned her son and fled. Iwai subsequently adopted the baby and named him Kaoru. 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.

Iwai's Confidant can be available as early as May 6th, however, it has a very steep requirement to commence. The protagonist must have at least Level 4 Guts (Dauntless) to start this Confidant, and it's very likely that, on the first playthrough, the Confidant would only be commenced in the final third of the game or not at all. To advance this Confidant past Rank 7, the protagonist's Guts need to be maxed out. Raising the rank of this Confidant will also raise the protagonist's Proficiency. Iwai's story revolves around his job as a storeowner handling special orders and his responsibility as a single father taking care of Kaoru. The protagonist finds employment with him under the pretense of being a gun enthusiast, helping him out with a deal involving his half-brother Tsuda who has been extorting him to do illegal firearms customization for a massive deal. It is later revealed that Tsuda had made a deal with overseas gang members in Hong Kong that resulted in him getting swindled of his money; having promised his superiors weapons, he looked to Iwai. Iwai later confronts Tsuda over the issue, but Tsuda is not swayed and pulls a gun on him, threatening his life. Iwai is well aware that Tsuda was going to kill him regardless but chose to comply to for Kaoru's sake. The Phantom Thieves then change Tsuda's heart, who repents and admits that he was losing his place in the organization to the younger members. Iwai was about to begin on the orders when Tsuda called and canceled the request. However, Tsuda's subordinate, Masa, tries to take Tsuda's spot and kidnaps Kaoru, threatening his life. Iwai then confesses the truth to him before Tsuda arrives, visibly annoyed at Masa for snitching on him. At the end of the confidant, Iwai gains the full trust of his son and is given a Gekko Pin, symbolizing the protection of one's home and family.

Following the protagonist's imprisonment in juvenile hall, if the protagonist completes his confidant, Iwai uses his Yakuza contacts to ensure the protagonist isn't bothered while in prison. Iwai's farewell gift to the protagonist on the last day after maxing his Confidant is a Gekko Pin, which allows access to all gun customization options, even the discount, once the protagonist starts his Confidant. Iwai's shop is inaccessible in this game, and most of its functions are available Sophia's Shop. Iwai himself does not appear: while a sign on the outside of Untouchable indicates the store is closed temporarily, the sign appears to have been there for some time.
