Somewhere in a dream, beneath frozen light and collapsing waterfalls…
Mizuki Hanegawa floated in the Ancestral Spring, her body curled beneath silver lotuses. Echoes thundered around her — screams of drowned soldiers, walls cracking, water retreating unnaturally.
Then came the voice.
Familiar. Deep. Twisted.
"You were never meant to rule, dear sister."
Her eyes snapped open — and standing upon the shattered shell of the Celestial Throne was Minaga Hanegawa, her older brother. His once-kind aqua eyes now burned with dark crimson. His robes were torn, revealing a spirit-forged armor that radiated corruption. Behind him, the Sacred Trident was broken.
"You abandoned the tides for mortals," he said. "So I claimed the realm in your stead."
"No… Minaga, this isn't you!"
But he raised his hand, and the oceans turned black. Tentacles of dried seaweed lashed toward her.
Mizuki screamed—
—
Morning — Human World
"AHH!"
Mizuki shot up from her lily bed, drenched in sweat. Her hands glowed faintly, water rippling in the air. The scent of human breakfast — instant ramen and socks — replaced the dream's brine.
Footsteps thundered in.
"You okay?!" Gojo burst in, shirtless, with a toothbrush in his mouth and… a pair of panties on his head.
She stared.
He blinked.
"…Oh. These aren't mine."
"GET OUT!!" she shrieked, hurling a pillow at him. He staggered back, foaming mint dripping from his lips.
Hikami-sensei groaned as she sat up from the couch — stark naked, with only a watermelon pillow covering her chest. "Too loud for 7 AM…"
Gojo stumbled back into the hallway… and tripped straight over Suma and Hiyori.
Suma was in a scandalously tight pink camisole and nothing else, grappling Hiyori in a chokehold. "YOU SLEPT ON THE LEFT SIDE OF GOJO! THAT'S MY SPOT!"
"I had night terrors," Hiyori said, voice flat, her robe half-open. "Also, I don't care."
Mizuki stared at the chaos — panties flying, Hikami yawning while nude, Gojo choking on toothpaste, and Suma literally biting Hiyori's thigh.
"This is… the mortal world?" she whispered, horrified.
"Good morning," Gojo wheezed, crawling up.
"Pervert!" Mizuki kicked him back.

Later That Morning — Apartment Kitchen
"Breakfast soup for breakfast people!" Hikami sang, now finally clothed in a tank top and apron — though the apron said "Slap the Chef."
Mizuki, now in a clean yukata, sat rigidly at the table, sipping miso broth and still clearly shaken.
Hikami sat beside her, munching toast. "I've enrolled you at our school."
"What?"
"Temporarily. It'll help you blend in while we figure out Minaga's intentions. Plus, you'll meet other Spirit-bound types."
Mizuki lowered her spoon. "…I dreamt of him. He's changed."
Hikami's face turned grim. "Then it's worse than I thought."
Gojo entered, drying his hair. "Hey, Mizuki. Sorry about… everything earlier."
She glanced away, flushing faintly. "Just avoid entering rooms without knocking."
"…Even when you're the only one staying in the bathroom?"
"Especially then," she said.
Suma leaned in, whispering, "Did he see your curves or just side-boob?"
"SUMA!"

At School —
A new day began. Gojo arrived half-exhausted, dragging his bag, sandwiched between Hiyori and Suma.
"Another day, another lecture ," he groaned.
Then the hallway shimmered.
A wave of soft mist rolled in.
Mizuki stepped through the school gates, sunlight sparkling against her new uniform — tailored perfectly to accentuate her grace. The white blouse hugged her chest, and the skirt flowed like petals. Every boy within ten meters fainted.
"She's like… an idol version of an elven goddess," someone whispered.
"I must be dreaming," muttered another.
Gojo ran over. "You okay?"
"I am… adapting," she said, glancing shyly. "You look… respectable today."
"Thanks. I wore deodorant this time."
Her smile widened.
Then— boom —the loudspeaker crackled.
"ATTENTION: Your new Physical Education instructor is here. Please report to the field."
Mizuki froze.
"No… It can't be…"

Field — PE Period
Every student gathered under the sun. Mizuki clutched Gojo's sleeve tightly.
Then she appeared.
Descending from a spiral of water — in a latex-tight tracksuit that left nothing to the imagination — was…
"Mizuki Hanegawa," she announced, voice oozing authority and allure. "Your PE teacher. Try not to drool too much."
She had the same glowing aqua eyes as Mizuki, but sharper. Her hair was tied in a tight braid, and her figure was… sinful.
Suma's jaw hit the dirt.
"WHO… IS SHE?" Gojo whispered.
"Battle General turned gym coach!" Minzuki winked at the students. "Now, boys. Shirtless pushups. Girls? Lap swims. Let's see those stamina stats."
"IS THIS EVEN LEGAL?!" shouted Hiyori, already unzipping her jacket in surrender.
Mizuki strolled past Gojo, trailing a water whip.
"You're Mizuki's protector,. " Hikami -Sensei purred. "Try to last longer than the last one."
Gojo paled.
"Hey, ," Mizuki said tightly. "Why are you here?"
"I volunteered. The human world needs sexy supervision," she purred. "Plus… I sensed you brother Dry Blight creeping in. I'm not letting you face him alone."
Mizuki looked down. "I can't believe Minaga…"
"He can," Hikami said coldly. "He always hated being second to a princess."

Later — Rooftop Vibes Again
After the most erotically charged PE session in school history (including Gojo accidentally grabbing Suma's chest while dodging water magic, and Hiyori kicking a perv into a pool), Mizuki found herself again on the rooftop — this time with a warm canned coffee in hand.
Gojo sat beside her, holding a towel over a bruised head. "Mizuki-sensei's a demon."
"She once fought off a sea kraken in heels," Hiyori murmured. "She thinks teasing is… motivation."
He glanced at her. "You okay? You were tense today."
She hesitated.
"My brother… he used to protect me. Now he's trying to destroy our home. I don't understand it."
Gojo looked down.
"I know what it's like. People you trust can break your heart."
She turned to him, gently. "But you seem… kind. Even when everything is madness."
He smiled. "I try."
"I'm glad I met you."
And then… a breeze lifted her hair, brushing against him.
Their fingers touched.
Their faces drew close—
"INTERRUPTING FAIRY SHIP MOMENT!!" shouted Suma, bursting through the rooftop door with a mop.
"GOJO, YOU PANTY-PERV, DON'T FALL FOR THE ROYAL LURE!" Hikami yelled from behind her.
Hiyori , sipping bubble tea, just purred, "Young love is delicious."
Gojo and Mizuki sighed in unison.
"…I'll still stay," Mizuki whispered, smiling.
