The episode focuses on Stendhal’s transformation into the infamous Hero Killer: Stain, while also highlighting the contrasting ideals of vigilantes like Koichi Haimawari (The Crawler) and Knuckleduster.
The Anatomy of an Episode
Stendhal’s Descent into Madness
The episode opens with Stendhal brutally dispatching members of the Abegawa Tenchu Kai, a villainous Yakuza group. His efficiency and skill with a katana, combined with his Quirk, Bloodcurdle, which paralyzes victims by ingesting their blood, are on full display. He then meets with Kuin Hachisuka, who provides him with blood samples, indicating a partnership. However, Stendhal secretly plans to target Kuin in the future, revealing his twisted sense of justice.
Soga’s Dilemma
Meanwhile, Soga Kugizaki and his friend Moyutu Touchi visit their hospitalized companion, Rapt Toukage. They discuss their past use of Trigger, aQuirk-enhancing drug, and the near-fatal consequences. Despite the risks, Soga is later manipulated by Kuin, who wants him to use Trigger to defend himself against Stendhal. Soga refuses, but Kuin forcibly injects him with Trigger, transforming him into a mindless “Instant Villain”.
The Clash of Ideals
As Stendhal confronts Soga, Koichi intervenes, attempting to save Soga. Stendhal, however, sees Koichi as an obstacle, viewing his support of someone he deems evil as a villainous act. Just as Stendhal is about to strike Koichi, Knuckleduster arrives.
Knuckleduster engages Stendhal in a battle, their contrasting ideologies clashing as much as their fists. Knuckleduster’s words about Stendhal’s masked persona deeply affect the sword-wielding vigilante. Stendhal realizes he has been separating his vigilante actions from his true self, using the mask as an excuse to avoid responsibility.
The Birth of Stain
The fight with Knuckleduster leads to Stendhal’s awakening. He retreats and confronts Kuin about his changing vision. Annoyed by her response, he injures her and discards his Stendhal identity by slicing off his own nose, symbolizing his transformation into Hero Killer: Stain. He declares that the only mark he will leave is the bloodstains in his path.
Key Themes and Analysis
The Blurred Lines Between Hero and Villain
Episode 6 further explores the complex moral landscape of “My Hero Academia: Vigilantes”. Stendhal’s actions, though aimed at eliminating villains, are brutal and extreme. Koichi’s desire to help everyone, even those deemed villainous, challenges the conventional definition of a hero. Knuckleduster’s more pragmatic approach highlights the difficulties of dispensing justice outside the law.
The Allure and Danger of Trigger
The episode also delves into the consequences of using Quirk-enhancing drugs like Trigger. Soga’s transformation into an Instant Villain demonstrates the corrupting influence of power and the dangers of relying on artificial enhancements. The negative effects of Trigger were previously seen when Tokage almost died.
Knuckleduster’s Impact
Knuckleduster continues to be a standout character, with his no-nonsense attitude and effective fighting style. His arrival to save Koichi is a classic hero moment, and his words have a profound impact on Stendhal, setting him on the path to becoming Stain.
Production Value
Studio Bones Film delivers another visually impressive episode, with fluid animation and well-choreographed fight sequences. The opening fight with the Yakuza and the battle between Knuckleduster and Stendhal are particularly well-executed. The episode maintains a consistently tense narrative tone, highlighting the emergence of Stain as a major villain.
Reception
The episode has been well-received by fans and critics, who have praised its action, character development, and exploration of complex themes. Some have noted that the reveal of Stendhal as Stain may not have had the desired impact for those familiar with the main series, while others have questioned the need to give Soga a backstory. Overall, however, “Crossing Lines” is considered a strong episode that significantly advances the plot and sets the stage for future conflicts.
