Chapter 55: Breathing Baldness - Saitama’s Training Arc?!
Morning sunlight poured over the newly rebuilt Butterfly Mansion, where the Hashira and Saitama had temporarily gathered. Though the major threat was gone, life in the Demon Slayer Corps hadn't slowed down. New training routines were being developed, and even after seeing Saitama's absurd power, the Hashira insisted he should still experience Breathing Technique Training.
"Think of it as cultural exchange!" Mitsuri beamed.
Saitama stood there in his usual bored stance, cape slightly swaying in the breeze. "Breathing? I do that all the time."
"No, not just breathing," Rengoku corrected, his voice full of fiery passion. "Breathing with your soul! Your will! Your spirit igniting with every inhale!"
"Sounds like yoga," Saitama muttered.

Lesson One: Water Breathing with Giyuu
Giyuu stood at the riverbank, instructing Saitama to mimic his stances.
"This is First Form: Water Surface Slash," Giyuu explained, demonstrating with grace and precision. The water rippled beautifully with his movement.
Saitama raised his hand — palm flat — and swung it casually. The entire river split in two, water flying sky-high before raining down like a monsoon.
Giyuu stood there, his stoic face even more unreadable than usual. "…Close enough."

Lesson Two: Thunder Breathing with Zenitsu
"This one's all about speed!" Zenitsu said, practically vibrating with nervous energy. "You need to feel the lightning in your veins!"
Saitama blinked. "I can already move faster than lightning."
"Y-you can?" Zenitsu's soul left his body for a second. "But it's about feeling cool while doing it! The dramatic pause, the flash, the BOOM!"
"Like this?" Saitama disappeared, and before anyone could blink, Zenitsu's hair was combed, his sword polished, and all the weeds in the training ground were neatly pulled out.
Zenitsu fell to his knees. "What am I even training for…"

Lesson Three: Flame Breathing with Rengoku
Rengoku wasn't discouraged by Saitama's overpowered antics. Instead, he saw it as a challenge.
"Listen, my shiny friend! Strength isn't just about power! It's about conviction! Passion! The will to set your soul ablaze!"
Saitama scratched his head. "My soul's fine, thanks."
"NO!" Rengoku struck a dramatic pose. "FLAME BREATHING FIRST FORM! UNKNOWABLE INFERNO SLASH!"
Saitama copied the move lazily, and somehow, the clouds split open and the sun shone directly onto the battlefield.
"…Yeah, okay," Saitama said. "This is kinda fun."

Hashira Verdict: He's Untrainable
After several rounds of 'training,' the Hashira gathered to discuss their findings.
"He doesn't need techniques," Muichiro said bluntly. "He's beyond technique."
"But… he could still learn about our culture!" Mitsuri argued. "Maybe he could join us! Become a Hashira! The Bald Hashira!"
"No," Sanemi muttered. "We're not calling him that."
Just then, Saitama walked by with Nezuko perched on his shoulder like a kitten. "Hey, you guys know where the nearest bathhouse is?"
The Hashira looked at each other. Maybe training him was pointless, but somehow, they couldn't imagine their strange, bald friend not being part of their world now.

Meanwhile… The Sin Awakens
Far away, in that cursed underground cave, the kanji for Sin (罪) pulsed faster. A shadow began to rise from the earth — something that even Muzan feared in ancient times. Something not even Saitama's punch might erase easily.
For now, though, no one knew. And for once, the Demon Slayers — and their overpowered guest — could enjoy a moment of peace.
