Mohsin Lag 
Fall 2026 just got darker. The Vermilion Mask (Shuiro no Kamen) premiered on October 10, and its first episode wastes zero time: cursed masks, a protagonist carrying an unforgivable sin, and a city hiding its grief behind festival balloons. With Blue Lock Season 1 director Tetsuaki Watanabe at the helm and The Apothecary Diaries composer Arisa Okehazama scoring it, this seinen dark fantasy is the season’s most promising new face — and Episode 1, “Peru, The Mask Maker,” proves why.
A Festival City With a Funeral Mood
The premiere opens in Lisblanc, a city draped in banners and balloons for its grand “Masquerade Ball.” But the people aren’t celebrating — they’re gloomy, eyes down, moving like a crowd at a wake wearing party clothes. Into that mood walks Peru d’Arrest, a young traveling mask maker running a cheerful street stall, calling out to customers like nothing’s wrong.
It’s a performance. Peru didn’t come to Lisblanc to sell. He tells a street-smart girl named Sona the truth in one chilling line: “I came to this country to destroy Gaston Roux’s masks.”
The Sin Seven Years Ago
Gaston Roux was one of the world’s three great mask makers — legendary craftsman, Peru’s master, and now seven years dead. The flashback fills in the horror: young Peru picked up the Mask of the Warrior God — a sentient mask voiced by none other than Akio Otsuka — and it took control of him. While wearing it, he slaughtered his fellow apprentices… and his own master.
That’s the engine of the whole series. Peru isn’t on a power-fantasy quest; he’s on a demolition mission against his master’s legacy, hunting down every Gaston mask in the world so no one else ever wears one and loses themselves. It’s guilt as a plot device, and it lands — hard.
Sona Steals a Mask (and the Show)
Sona — quick-fingered, streetwise, zero patience — robs Peru mid-conversation. What she takes matters far more than it looks, and the episode is smart enough not to explain why yet. Their chase collides with Lisblanc’s real nightmare: the military police, commanded by Totoque, who serve the cruel new king and put down civilians without blinking. Children included.
Peru’s response shows exactly who he is. He plays dirty — baiting, bluffing, then snapping on the Mask of the Spider to leap himself and Sona over the castle walls to safety. This is not a typical shonen hero. When cornered, Peru is calculated and ruthless, and the show clearly wants you to be a little unsettled by that.
Inside the Castle, and the First Real Monster
The two make an uneasy alliance: Sona wants in on the palace, Peru needs in to destroy the Gaston masks stored there. The infiltration goes sideways fast — Totoque finds them, and Peru cuts through his lackeys in quick, lethal bursts that show off the masks’ range. But every win only raises the stakes, because the real threat was watching the whole time.
Lord Gouon, ruler of Lisblanc, makes his entrance in the closing minutes — and completely outwits Peru in an almost omniscient way. Fans are already calling him Yhwach-flavored: calm, patient, three moves ahead of everyone. If Gouon is the ceiling of this show’s power scale, Peru has a very long road.
The Cliffhanger: Sona Isn’t Who You Think
The episode’s final twist reframes everything: Sona’s full name is Sonarue Maywood — the disgraced princess of Lisblanc, hinted at in subtle foreshadowing all episode. Her backstory is teased to be just as bloody as Peru’s, and her need for revenge outweighs any alliance. The preview guide crowd put it bluntly: the “heroine” betrays the role and sets herself up as the story’s first real boss — and her revenge may kill many of her own former subjects before the night ends.
Peru spent the episode trying to keep masks out of desperate hands. Episode 1 ends with one sitting in the most desperate hands in the city.
What Episode 1 Sets Up
- The mask hunt — Gaston’s masks are scattered across the world; Lisblanc is stop number one of many.
- Gouon’s endgame — a ruler who anticipated Peru’s every move clearly knows more about the masks than he lets on.
- Sona/Sonarue’s revenge — the show’s first arc is shaping up as protagonist vs. ally, not hero vs. villain.
- The Warrior God — a talking, sentient mask with Otsuka-level menace is going to resurface. Count on it.
