"Balance–Breaker!"
Tsuna spoke the release words, and the crimson gauntlet on his left hand erupted in red light, spreading across his entire body. Scarlet armor covered him from head to toe, and a pair of radiant crimson wings unfolded behind his back.
"Boost!"
A deep voice echoed from within the armor, and in the next instant, Tsuna's aura flared violently.
"Are you ready?"
Encased in his red armor, Tsuna looked at the three standing before him.
"Already ready!"
Tiona was bursting with excitement—she could hardly wait to move.
"Don't hold back. Treatment after this won't be an issue… I understand that clearly."
Tione's eyes held no trace of hesitation, only pure fighting spirit.
She might love Tsuna, but as an Amazon, she could never pull her punches in an official match.
Precisely because it was someone she loved, she had to go all out.
"..."
Riveria said nothing, her gaze locked firmly on Tsuna.
She could feel the overwhelming pressure pouring off of him—his strength was boiling, rising sharply.
I can't treat him as an ordinary Level 2 anymore. I have to face him as an equal.
Her hand tightened around her magic staff without her realizing it.
"O spirits of the forest—"
But before Riveria could finish the first verse of her chant, a flash of red light appeared before her eyes.
A fist was already flying toward her face.
So fast!
Just before it connected, a massive blade swung in from the side, intercepting the strike.
Tiona's great kukri.
Clang!
The impact made Tiona's arms go numb, but she managed to block it.
"Like I'd let you land a hit that easily!"
Behind her, Riveria continued her chant, unbroken.
"...Grant my wish, garb of the forest—!"
In that moment, Tsuna shifted his power. The recoil sent Tiona stumbling forward, unable to react in time.
The red blur darted again, chasing Riveria.
This time, his speed dipped slightly—just enough for Tione to close in.
"Orraaah!"
Both hands gripping her kukri, Tione blocked the incoming punch, buying Riveria precious seconds.
"...My name is Alf!"
"Veil Breath!"
A thin layer of magical cloth enveloped Tione's body, calming the tremors in her arms caused by that violent impact.
Above, Tiona's giant kukri came slashing down again.
Tsuna didn't try to meet it head-on—he stepped back instantly.
"Boost!"
The armor's deep voice echoed once more.
Power surged, and his speed exploded.
He halted mid-step, then lunged forward with blinding momentum, slipping through the sisters' guard and appearing right before Riveria.
A punch struck her abdomen point-blank. Crimson magic gathered into a sphere between his fist and her stomach.
No hesitation. No restraint.
The condensed energy shot through her body like a bullet.
Riveria's figure crumpled, collapsing like a broken doll.
"Riveria!"
Two voices shouted from behind as the air trembled with their killing intent.
Tsuna didn't need to look back—he could feel their fury burning.
Even if they knew this was a simulated battle, seeing Riveria "killed" before their eyes had snapped something inside them. Amazons were simple creatures—their emotions ran wild.
But they weren't the real threat.
A flicker of flame passed through Tsuna's eyes. The fallen Riveria dissolved into mist.
An illusion… When did she cast it?
He shifted his gaze. Firelight danced across his irises as Harmony sharpened his vision—the world burned in vivid color.
A faint blue flame flickered within the illusion, tracing the outline of a moving figure.
Found you.
But… looks like Tiona and Tione are angry now.
Without looking, Tsuna sensed both their weapons closing in fast.
His wings flared open.
Clang!
The light wings caught their combined strike.
BOOM!!!
The great kukri and twin short kukri ignited with scarlet flame.
Crack, crack, crack!
Fractures spread across the glowing wings, breaking apart under Disintegration.
Their emotions are spiking—so that's what triggered their power?
Tsuna understood instantly.
Riveria's mana is surging—she's almost ready.
So this is the pressure of a Level 6 and two Level 5s working together…
But still—
"Boost!"
"Boost!!"
"Boost!!!"
Power multiplied threefold. Red energy flooded outward, forcing both sisters' weapons back with brute force.
In that instant, Tsuna dashed toward Riveria's real position.
"Don't you dare run!"
His wings were suddenly caught, his burst of speed halted.
Tione.
"Heehee~ Tsuna, you're not going anywhere!"
Then warm arms locked around his torso.
Tiona.
The strength behind her grip was incredible—even Tsuna couldn't break free.
"!?"
And at that exact moment, a surge of mana erupted ahead—Riveria's spell reached its climax.
"Riveria, now!"
Neither Tiona nor Tione loosened their grip.
They both knew—if they let go, Tsuna would dodge it.
So they held on, no matter what.
"...Freeze-bound earth, sweeping blizzards, eternal winter—my name is Alf!"
"Wynn Fimbulvetr!"
Three raging snowstorms sealed off every escape. The instant the spell completed, Tsuna and the sisters were engulfed in a world of solid ice.
