Chapter 5 (Vigilantes)

Bee (蜂) is the fifth chapter of Hideyuki Furuhashi and Betten Court's Vigilante - My Hero Academia: Illegals.

Summary
Teruo Unagisawa, the over-enthusiastic fan with a slime-like Quirk who attacked Pop Step, is being questioned by the Police Force. Teruo reveals that someone gave him the Trigger drug and told him to use it when things were not going his way which will make him super strong and in return he must not tell anyone about Trigger. Naomasa summarizes that Mario Kugutsu, Souga Kugizaki, Moyuru Touchi, Akira Iwakou and now Teruo have been users of the Trigger drug which has caused the "Villain Out-Break Incidents" occurring in succession over the past few weeks. Each of them have been confirmed to use a drug called "Trigger", a Quirk Induction substance moments before their villainification. Naomasa's colleague, called Tanema, believes that since the Trigger drug has been distributed in specific places they could track down the dealers of the Trigger drug. Tanema is confused as to why the dealers would hand the Trigger drug out for free. Naomasa ponders about the objective the dealers want to achieve. Tanema notes that objective is the keyword and surmises that the dealers of the Trigger drug may want to make massive profit or an upheaval of public order, although he may be overthinking this. The Police Force release Teruo without any charges as he only caused minor damage and Trigger isn't a scheduled drug.

Teruo is walking on the streets while Naomasa keeps an eye on him for a short while. Juubei and Ichimoku see Teruo. At Kouichi's home, Pop Step has received a text message from Juubei and Ichimoku; Kouichi thinks its polite they sent her a message while Pop Step tells him not to laugh. Pop Step tells Kouichi that they ran into the over-enthusiastic fan from the other day and they are now all friends. Juubei and Ichimoku might be able to get more information about the person who gave the drug to Teruo. Kouichi says that they should not let Knuckleduster know as he might beat the information out of Teruo. They decide to talk it out with Teruo themselves.

On their way, they encounter a fan who recognizes Pop Step and takes a picture with her. Kouichi and Pop Step meet up with Ichimoku who tells them that Juubei is with Teruo. Unfortunately, Knuckleduster is in the same area and wants to join the conversation. Meanwhile, the fan that took a picture with Pop Step called Quinn Hachisuka is gleeing over the picture. Unbeknownst to her, a huge bee slips under her eye patch. While his friends point this out to him, he leaves immediately for work. Quinn reveals herself to be a high school junior...and part time villain. Quinn's Quirk is called "Queen Bee" which allows her to control worker bees to do her bidding. Quinn sends the bees filled to the brim with drugs around town to cause all sorts of trouble. Quinn's army of worker bees start attacking and injecting drugs into innocent civilians, turning dozens of people into Impromptu Villains. As a result, the civilians' Quirks go out of control and start causing chaos. As civilians run away from the Impromptu Villains, Naomasa calls for backup.

On the other side of town, Kouichi and Knuckleduster hear the disturbance. Suddenly, Heroes appear on the scene such as Airjet and Turbo Hero Ingenium. Other Heroes including Endeavor, Midnight, and Eraserhead appear as well. The Heroes manage to subdue the Impromptu Villains. All Might himself appears and subdues a large Impromptu Villain. All the people Impromptu Villains have been suppressed by the Heroes in a short space of time. Kouichi wonders where Knuckleduster went to.

Knuckeduster manages to catch one of Quinn's worker bees while Juubei tries to find Teruo. Knuckleduster confronts Juubei in anger and informs him that someone is out there that caused the chaos earlier on. Knuckleduster crushes the worker bee, causing Quinn's eye to bleed. Quinn is annoyed that one of her worker bees have been hurt. Quinn tells Teruo that she is fine and they should get going, telling him that they are friends and offers to show him a picture of Pop Step.

Kouichi, Pop Step, Juubei, Ichimoku sit at a cafe while Knuckleduster mulls over being unable to find the person responsible for the chaos today. Kouichi's group continues enjoying the transient peace they are experiencing, blissfully unaware of the quiet malice lurking in the shadows.
