Chapter 67
 âThe Demonfolkâs Whimsyâ [Demon Princess Arc âŚ]
The morning bell rang three clear times.
The shadows of the spires were short, and the air was dry â a perfect day for physical training.
âAlright, time for morning exercises. Safety first. You get points off for being reckless.â
Kai stood at the center of the schoolyard, whistle in hand.
The first-year students answered in unison, âYes, sir!â â though their eyes sparkled a little too brightly.
âWarm-ups. Shoulders, hips, ankles. Donât overdo the momentumââ
Before he could finish, one of the first-years lightly hopped â
Pop! Like stepping on a pebble, and in the next instant, the student soared higher than the treetops.
âWâwhoa!!â
âLook, teacher! I can feel what itâs like to be a bird!â
âBirds donât fly in that kind of trajectory!â
Another student grabbed the horizontal bar, performing a string of front flips from an underhand grip.
With each spin, light flashed â and the spectatorsâ murmurs spread like waves.
âHey, hey, hey! This ainât a circus. Youâre not competing, youâre centering yourselves.â
âYes, sir!â
Their answers were perfect â if only their interpretation of âlightlyâ didnât translate to âfull power.â
Soon a line of one-handed handstands appeared, and one kid even darted across the top of a ladder as if escaping through ropes.
(Their body control is flawless from the start⌠but they donât act like theyâre âspecialâ at all.)
Kai pressed his temples and blew the whistle.
âGather up. One last thing â if your strength breaks the rhythm around you, thatâs not âpower,â thatâs just ârampage.â
Real strength is being able to match your stride with the person next to you. Got it?â
âYes, sir.â
The reply fell across the schoolyard a bit quieter than before.
After class.
When Kai brushed off the sand and was heading back toward the classroom, two first-years ran up.
âTeacher, what was wrong with my jump today?â
âThe first step. Donât kick the ground, stroke it. If your impactâs too strong, the shock leaks out around you.â
âStroke itâŚ?â
âYeah. Try that next time. If you pull it off, you get extra candy.â
Their smiles bloomed like spring flowers.
Sweet rewards worked better than any magic.
The morning lectures covered the basics of calculus and a review on ârounding boundaries.â
As the chalkboard filled, the first-yearsâ hands moved quickly.
They added tiny correction lines in the margins, smoothing out formulas as they went, eyes fixed straight ahead.
(They absorb too fast. But thatâs not bad. And itâs not shallow, either â itâs just that I canât see the bottom.)
During the lunch break, a pleasant smell wafted down the hall.
âTeacher! We brought you something!â
Around the corner came a group of first-years pushing a small cart with a pot and a basket of bread.
Inside the pot was clear soup, sprinkled with fine herbs.
âWe did it right today!â
âWanna taste?â
âBefore tasting, letâs talk about heat control. Yesterday your steam turned rainbow colored.â
âWe learned our lesson!â
The aroma teased his nose. He took a spoonful.
The flavor spread gently across his tongue, with a faint sweetness at the end.
ââŚGood. Who came up with the recipe?â
âWe all tested it together and adjusted it â kind of like your ârounding the boundaryâ formula!â
âStop using formulas to make soup. âŚWell, actually, it works. Itâs good.â
Laughter rippled around them.
Someone from the second-year class shouted, âThe âbirdâ from earlier makes soup thatâs light as air too!â â which made no sense, but drew more laughter anyway.
The afternoon was cleaning time.
From one end of the hall to the other, rags raced across the floor.
The first-years seemed oddly delighted.
âTeacher, look! Itâs like a mirror!â
âCareful not to slip now.â
Before he finished speaking, one second-year nearly skidded â only to be caught instantly by two first-years, who cushioned him at perfect angles.
ââŚYouâre polishing too well. Remember, the floorâs a stage, not ice.â
âYes, sir.â
They nodded, dipped their cloths in fresh water, and adjusted the strength of their strokes â learning âmoderationâ through their bodies at an incredible pace.
After school.
The gatekeeper came with a message: âThe shopkeepers are asking for you.â
When Kai went to see what was up, the market women laughed.
âThese kids of yours are too good at haggling!â
Sure enough, the first-years were working at a food stall, deftly turning skewers over the grill, waving through the smoke.
âTeacher! We tried grilling a few ourselves!â
âRemember, âa pinchâ of spice, not âthe whole jar.ââ
âWe learned that!â
He took one skewer and bit in.
The surface was crisp, the center tender, the spice giving way to a chase of sweetness.
âTasty. âŚJust donât haggle too hard, alright? And here â this isnât âtuition,â itâs a tip.â
He handed over a few coins, and the vendor smiled kindly.
âKai-sensei, youâre such a good man.â
âTell folks my real jobâs teaching, not bargaining.â
They laughed together.
Nearby, some students holding skewers were staring at a theater poster.
âWe wanna see this next!â
âItâs a tragic romance. Youâll cry so hard your throatsâll dry out.â
âIf that happens, weâll have your candy, teacher!â
âIâve only got so much stock.â
Still, his candy jar felt a little lighter again.
Toward sunset.
In the courtyard, a mix of first- and second-years practiced âlight sparring.â
No clang of metal â just soft touches of âformsâ meeting, angling, deflecting, flowing back.
Rutia noticed and approached.
âYouâre not doing anything dangerous, are you?â
âNo, senpai.â
Then Liricia came and stood beside her, arms crossed.
âTheir form matching has improved,â Liricia said quietly.
âAt this rate, I might be able to spar with them without leaving a hole,â Rutia added with a teasing smile.
âAre you praising them or threatening them?â Kai muttered.
The group laughed in unison.
As he watched, a second-year tripped â and three first-years moved instantly, each from a different angle, catching shoulder, elbow, and waist, redirecting the force smoothly into the ground.
No one fell. Not even dust rose.
The saved student blinked in surprise, then smiled shyly.
âThanks. That was⌠really good.â
âWe practiced what you taught us â the âroundingâ method.â
âStop treating âroundingâ like itâs a magic spell.â
By now, laughter was the classâs shared language.
As the sun sank, Kai stopped by the faculty room.
The headmaster stood by the window, the pomegranate-colored sky glinting in his glasses.
âKai-sensei. Lively day, isnât it?â
âMore than lively. âŚIntense.â
âIntensity keeps boredom away.â
âMy stomach disagrees.â
âYour candy will protect it.â
The headmaster brushed off the complaint with his usual half-smile, the wrinkles at his eyes deep and kind.
On the walk to the teachersâ dormitory, Kai felt eyes on his back.
Turning, he saw several first-years following at a distance.
âWhatâs this? Practicing tailing someone?â
âNo, sir⌠we just wanted to make sure no one bothers you on the way back.â
âWhoâd even try?â
âThereâs a rumor about a âpowerful barrierâ in the alleys recently⌠just in case something happens againââ
âYouâre a cautious bunch. I appreciate it, but Iâll be fine till the dorm.â
âThen at least to the gate.â
They wouldnât budge.
In the end, they walked him all the way to the dorm gate, stopping neatly under the lamplight to bow deeply.
The bow was natural â not something theyâd been taught, but something that came from within.
(Theyâre genuine. Honest in their strength⌠and that same scent of instinct again.)
Before opening the door, Kai turned back.
âFollowing orders is easy. But if you only follow, you donât learn.
Tomorrow, bring me one formula thatâs entirely your own.â
âYes, sir.â
This time, their voices sounded calm and grounded.
That night, the cafeteria was lively as ever â almost like a small festival.
The group that had gone to the theater tearfully reenacted famous lines,
the cooking team debated spice ratios,
and the martial arts group discussed what âmoderateâ floor polishing meant.
At a corner table, Liricia quietly opened her notebook, while Rutia beside her pointed things out with her pen.
Their shoulders brushed occasionally â neither minded.
Watching from afar, Kai poured tea for a first-year sitting across from him.
âAdd your own sugar.â
âWhat about you, teacher?â
âThree lumps. Always.â
âThatâs too much.â
âItâs for brain work.â
Laughter gently rippled across the table.
Back in his room, a stack of papers awaited him â the first-yearsâ independent study work.
Each sheet was full of auxiliary lines, tiny notes, and corrections.
One studentâs formula was annotated by another, then circled by yet another.
âTheyâre grading each other already⌠Well, I donât mind.â
As he added red marks, a faint smile tugged at his lips.
He popped a candy into his mouth and opened the window.
A cool breeze flowed in, mixing with the chalky scent of the papers.
(They seem whimsical, but their eyes see deeply.
They seem free, but thereâs structure underneath.
I just have to make sure that structure doesnât stop at âobeying the strong,â
but grows its own legs â right there on the blackboard.)
Looking down at the courtyard, he saw a few first-years still there, walking slowly under the lamplight.
Not running, not jumping â just practicing matching their steps.
Walking.
Such a simple act â yet so beautiful.
From afar came laughter.
Nearby, the chirp of insects.
The spire shadows melted into the night, and stars began to blur.
Tomorrow morning, it would start again â with the whistle.
And the blackboard.
The blackboard never lied.
And in that truthful space, Kai Cross would keep giving his students the freedom to think for themselves.
