I will try to explain the training about..I'm gonna Google it, let's begin with Akaira's.
Akaira’s Training: The Storm CenterAkaira brings 12 years of teaching experience to the table, making her camp the most structured and disciplined.The Routine: Recruits are placed in high-altitude, high-wind valleys. They must practice their sword swings while fighting against simulated gale-force winds.The Focus: She teaches her "Wind and Storms" concepts by forcing recruits to learn how to change their breathing mid-swing to match shifting wind currents.The Atmosphere: Firm but deeply maternal. She pushes recruits to their absolute limits but always ensures they have a hot meal at night—reminding her of the care she wished she could still give Sanemi and Genya.
Next.
Sai’s Training: The Unyielding SteelSai is absolutely terrifying, and his camp is feared by every single recruit who enters the northern mountains.The Routine: Recruits are forced to wear heavy steel-weighted vests and blindfolds. Sai stands in the center of a rocky arena playing his four-stringed Biwa lute. Recruits must dodge heavy swinging boulders purely by listening to the vibrations and rhythm of his music.The Focus: Developing sensory awareness, pure physical durability, and "Steel" muscle density. If a recruit complains about the weight, Sai simply glares with his blind eyes until they shut up.The Atmosphere: Intense, silent, and intimidating. However, those who pass earn a rare nod of respect from the giant.
Next.
Ace’s Training: The Flashy TempoAce’s training is loud, chaotic, and heavily focused on speed and explosive power.The Routine: Ace sets up training grounds filled with hidden traps that detonate with loud firecrackers. Recruits must sprint through the course at top speed, tracking the sound of Ace’s twin blades clicking together in the distance.The Focus: Rhythm, explosive footwork, and sensory overload tolerance. Ace trains his recruits to fight even when their vision is completely obscured by smoke or explosions.The Atmosphere: Incredibly energetic. Ace’s four wives (Homura, Kaede, Tsubaki, and Asa) act as the drill instructors, cheering on the successful recruits and relentlessly teasing the ones who trip over the traps. Ace himself is constantly bragging about his techniques, making it a lively but exhausting camp.
Next.
Kari’s Training: Fluid Poison & EnduranceKari runs the medical and tactical side of the camp, focusing on flexibility, poison resistance, and recovery.The Routine: Recruits must practice their sword forms underwater or in deep marshes to master the fluid movements of Water Breathing. Afterward, they spend hours memorizing different demon toxins, wisteria properties, and medical field-dressing.The Focus: Precision strikes, agility, and mental sharpness under pressure.The Atmosphere: Kari smiles warmly the entire time, even when she is giving a terrifying lecture about what happens if a recruit messes up a poison antidote. Her sweet demeanor makes the brutal physical conditioning somehow even more intimidating.
Next.
Mizuki’s Training: Heart & Heavy LiftingMizuki’s camp looks cheerful from the outside, but it is a trap of pure physical exhaustion.The Routine: It starts with a massive, endless feast of food to build up stamina. Immediately after, Mizuki forces the recruits into intense, high-intensity strength training—lifting massive logs, pulling boulder carts, and ending the day with a mandatory arm-wrestling match against her.The Focus: Boosting muscle density, pure physical strength, and maintaining a positive, unyielding spirit in battle.The Atmosphere: Wholesome but bone-shattering. Mizuki is constantly cheering, laughing, and giving out hugs, but she will not let anyone leave until they can successfully move a boulder.
Next.
Kojuro’s Training: The Absolute ZeroKojuro’s camp is held in the deepest, freezing snowstorms of the northern mountains.The Routine: Recruits must submerge themselves in icy waterfalls to control their body temperature through breathing, then immediately transition into high-speed sword sparring in waist-deep snow.The Focus: Combining the explosive heat of Flame Breathing with the numbing, precision-chilling forms of Ice Breathing. Recruits learn how to conserve their stamina in freezing temperatures.The Atmosphere: Completely silent. Kojuro doesn't say a single word during the entire training cycle. He simply demonstrates a form once, stands perfectly still like an ice statue, and expects the recruits to mimic it perfectly.
And finally.
Nico & Maktia’s Special Role Because Maktia cannot walk and Nico has permanent frostbite on her legs, they do not run standard physical training camps. Instead, they act as the Strategic Heart of the Northern Hashiras.The Routine: The highest-ranking recruits who survive the other camps are brought to the headquarters whiteboard. There, Maktia tests their tactical minds, teaching them how to coordinate attacks, read demon movements, and defend a position seamlessly.Nico's Presence: Nico usually sits quietly on Maktia's lap or Kojuro's shoulders during these meetings. Her Mist Breathing allows her to notice tiny, hidden details in a recruit’s posture or breathing that everyone else misses. She will quietly point out a flaw, completely altering how a swordsman holds their blade.The Reward: Recruits who pass the final tactical exam are given the honor of helping Nico tend to her secret garden or taking a slot on the whiteboard calendar to help Maktia walk around the estate.
