There’s a particular electricity that runs through a story when music arrives not as decoration, but as heartbeat—and the new season of the anime Blue Miburo is stepping into its next era with two artists who understand how to score a soul in motion.

On December 20, the series returns on Yomiuri TV and Nippon TV networks with its second chapter, The Serizawa Assassination Arc, and with it come two new companion songs: an opening theme by Ryosuke Yamada and an ending theme by Soushi Sakiyama. Together, they feel less like theme songs and more like emotional doorways into the lives of the warriors we’re about to follow.

Blue Miburo has always pulsed with the tension between youth and history, telling the story of the Miburo—those early, rough-edged blades who would later become the Shinsengumi—as they fight to protect Kyoto with nothing but conviction and the bodies they’re willing to throw into a fraying world. This new arc tightens its focus on Serizawa Kamo, a man whose pride as a samurai glows so fiercely it casts shadows everywhere he stands. The season promises a reckoning—political, personal, moral—and the music mirrors that heat.
Ryosuke’s opening theme, “Blue Noise,” is a declaration. After playing Okita Sōji in the film Baragaki: Unbroken Samurai (Moeyo Ken), Ryosuke carries a quiet, lived-in tenderness for the Shinsengumi, and you can hear that intimacy in the way he builds this track. Blending rock, hip-hop, and Japanese musical textures, the song feels like a sprint through a night where steel catches moonlight—restless, sharp, but humming with purpose.
“The lyrics are deeply rooted in the world of Blue Miburo,” Ryosuke says, describing a sound designed to run alongside the story’s urgency. It’s a piece that doesn’t just open an episode; it cracks the sky open. “Blue Noise” will also mark Ryosuke’s first CD single under his own name when it releases on January 14, giving fans a new milestone to hold onto.

If Ryosuke lights the match, Soushi’s ending theme, “Utakata” (Ephemeral), carries the smoke—the kind that lingers on skin, memory, and unspoken feelings. Soushi began writing with a single line that hit him like a bruise: Even when you think you understand something painfully well, there is a truth so dull it escapes you. From that paradox, he composed a song that lives between fragility and faith: a promise that even in the harshest moments, the warmth of shared pasts doesn’t fade.
“I wanted to believe in that warmth,” he says. “And hope that someday, you’ll cross paths with that kindness again.”
“Utakata” releases digitally on December 21, with a CD single to follow on February 11—a quiet, gentle offering in a story otherwise sharpened by blades.
Both songs already appear in newly released promotional videos on the anime’s official X account and the Yomiuri TV anime YouTube channel—a first glimpse at how these tracks braid into the arc’s emotional spine. And as the season steps forward, new cast additions—Kazuki Urawa, Rikuya Yasuda, Kosuke Takaguchi, Ryo Sugisaki, Mitsuki Saiga, and Junya Enoki—signal that the story’s world is widening, its center of gravity shifting just enough to keep us breathless.
What emerges is a season preparing to carve deeper, to ask harder questions about loyalty, pride, and the blurred line between brotherhood and destiny. And with Ryosuke and Soushi anchoring its soundscape, Blue Miburo is not just telling the story of the Shinsengumi’s beginnings—it is singing their heartbeat anew.
Ryosuke Yamada – Comment
“When I was approached about performing the opening theme for Blue Miburo, I was simply overjoyed.
This new song, ‘Blue Noise’, is my first piece as Ryosuke Yamada that blends elements of rock, hip-hop, and traditional Japanese sounds into something truly new. The lyrics were written with Blue Miburo in mind, carefully grounding themselves in its world. And with its sense of speed and forward motion, I think it fits the atmosphere of Blue Miburo perfectly.
I would be so happy if you enjoy it.”
Soushi Sakiyama – Comment
“My name is Soushi Sakiyama, and I have the honor of performing the ending theme for the Blue Miburo: Serizawa Assassination Arc anime.
This chapter—its precious comrades, and the unspoken feelings crossing between them—moved me deeply. I began writing the song from the opening line: ‘Even when you should understand something painfully well, there’s a truth so dull you fail to grasp it.’
No matter how harsh life becomes, precious memories do not fade, and I want to believe in that warmth.
May you one day encounter that same kindness again. That is the heart of this song.
As a fan myself, I’m looking forward to seeing the characters come alive in animation in this arc.
And I truly hope you will enjoy this song, ‘Utakata’, as well.”
