Sunlight poured down the street, turning windows into dazzling mirrors. The group of boys walked with easy confidence, already acting like kings.
"You know that new transfer girl?" one said, buzzing with excitement. "She's really sexy, right, Raizen?"
Raizen grinned. "Yeah, definitely sexy… but she's pretty short."
Another boy rubbed his chin, smirking. "Who cares about height? Her breasts are massive—that's what matters."
Raizen rolled his eyes. "Massive? Those are smaller than golf balls, man. Come on."
Suddenly a squad of white-yukata Resonants sprinted past, katanas at their sides, shouting about an Echo appearance.
"Another Echo," Raizen muttered, watching them vanish around the corner.
Kametsu snorted. "These Resonants are getting weaker every day."
"Knock it off, Kametsu," Raizen said, already turning toward school.
Kametsu fell in beside him, grinning wide. "Today's the day. We register for the Resonants entrance exam, pass, become official Resonants… and then we get to take down Echoes for real."
Raizen's gaze drifted ahead, locking onto a girl whose uniform shirt was stretched tight over her huge breasts.
"Wow," he breathed. "Look at those… incredible breasts."
Kametsu followed his line of sight. "Man, those are like perfect watermelons."
A sharp smack landed on the back of Kametsu's head.
"Again?" The female teacher stood with arms crossed under her own impressive chest, glaring. "You two are hopeless perverts."
Raizen gave a nervous smile. "We were just… giving her a compliment, sensei."
He grabbed Kametsu by the collar and pulled him away before she could hit them again.
In the classroom they dropped into their usual seats.
"Being adults is useless if we still don't have girlfriends," Kametsu groaned, head on the desk.
Raizen sighed. "Calm down. It'll happen when the time is right."
The door slid open.
Yuri Hanasaki stepped inside.
Her school skirt was short, hugging thick thighs and a round, full ass that swayed noticeably with each step. The blouse clung desperately to breasts so large they strained every button.
Raizen's eyes widened. "Whoa… she's insanely sexy."
Kametsu tracked her shamelessly. "That's Yuri Hanasaki. Word is she's taking the entrance exam too. Imagine if we get paired up."
Raizen grabbed his friend's collar. "Hey—that's future sister-in-law material. Stop staring like that."
Kametsu laughed. "Keep dreaming, you're still single, idiot."
The teacher entered, voice cutting through the chatter.
"Everyone, look here."
"Good morning, ma'am," the class replied in unison.
She nodded sharply. "The Resonants entrance exam begins today. This is for adult students only—no minors allowed. The physical and mental training will be extremely intense. Pairs will be decided after registration. Only five pairs—ten students total—will be selected. Prepare yourselves."
She left without another word.
Raizen blinked. "What did she mean by pairs?"
Kametsu leaned back, smirking. "It means only ten spots. We're nineteen—old enough. We just have to be better than everyone else. Top ten make it."
Raizen nodded slowly. "So we need to stand out…"
"Exactly." Kametsu stood. "Let's go register before the line gets crazy."
In the corridor Raizen muttered under his breath, "I hope I get paired with someone really sexy."
Kametsu clapped him on the shoulder. "Stay positive. Good things come to those who believe."
They nearly bumped into Yuri.
"Hello," she said softly, a little shy. "Can you tell me where the registration office is?"
Raizen straightened instantly. "Of course—we're heading there right now. Want to come with us?"
She smiled sweetly. "Thank you so much."
The hall was packed. A long line stretched out the door.
"Great," Raizen muttered. "We better end up high on the list. Only top ten boys get in."
On the girls' side, Yuri leaned toward her friend. "What do you think, Yukie?"
Yukie's eyes were sharp. "That old teacher won't put our names high unless we give him a reason. We have to… convince him."
Up front, a girl leaned over the desk—top buttons open, deep cleavage on full display.
The teacher's eyes lingered. "Of course, beautiful." He wrote her name in fourth place.
Yukie rolled her eyes. "See? Total pervert."
When their turn came, Yuri and Yukie stepped forward together. They undid a couple of buttons and leaned in close—breasts pressing against the edge of the desk, curves impossible to ignore.
"Good morning, sir," Yuri said, voice soft and sweet.
"Our registration, please," Yukie added with a slow smile.
The teacher's gaze dropped and stayed. "Of course, ladies…" He placed them sixteenth and seventeenth.
They walked away breathing sighs of relief.
"That was close," Yuri whispered.
At the boys' desk, Raizen and Kametsu leaned in.
"Hello, Miss Yumi," Raizen said cheerfully.
"Our registration," Kametsu added with a grin.
Yumi rolled her eyes. "You two perverts. I already saved first and second place because I knew you'd show up."
She wrote their names at the top.
Raizen couldn't resist. "By the way… what's your bra size these days?"
Yumi's pen stopped. "Want me to erase your names?"
Kametsu laughed, already backing off. "See you soon!"
As they left, Yukie watched them go, shaking her head with a small smirk.
"Those two idiots…"
The hallway hummed with tension—exams, training, Echoes, power.
And beneath it all, the electric possibility of being paired with someone whose body could stop hearts. The next morning the classroom buzzed with nervous energy. Sunlight slanted through the windows, catching dust motes and highlighting every curve in the room.
Raizen leaned back in his chair, arms behind his head. "Man… I just hope I get paired with someone good. Someone really good."
Kametsu dropped into the seat beside him, already scanning the room. His eyes immediately locked onto a group of girls near the front—uniforms tight, breasts straining the fabric with every breath or shift.
"Don't get ahead of yourself, Raizen," he muttered, though his gaze never left the view. "Let fate do its thing."
The door slid open with authority.
Miss Yumi stepped in. Her hips swayed naturally, ass jiggling just enough with each step to draw half the boys' attention instantly. She carried the registration book like a weapon.
"Settle down," she said, voice calm but commanding. "Today I announce the confirmed pairs for the entrance exam. These are the first five. The remaining five will be finalized later due to registration issues. Until then, the selected students will report to the assigned training rooms with their partners. No exceptions."
Everyone sat up straighter.
"We're ready, ma'am," the class chorused.
Yumi opened the register, eyes scanning the page once before speaking.
"First pair: Kametsu and Yukie."
"Second pair: Yuri Hanasaki and Raizen."
"Third pair: Hatsumi and Sahito."
"Fourth pair: Hiroshi and Sami."
"Fifth pair: Tasumi and Mesiho."
She closed the book with a soft snap.
"The rest of you—wait for further notice. Paired students, move out now."
She turned and left, ass swaying one last time as the door shut behind her.
Raizen let out a slow breath, a wide grin spreading across his face.
"That's… great," he whispered to himself, heart suddenly hammering.
Kametsu leaned back, smirking. "Yukie, huh? Not bad at all. Girl's got fire… and everything else."
Before Raizen could reply, a soft shadow fell over their desk.
Yuri stood there, leaning forward slightly to speak. Her blouse pulled tight across her huge breasts; they shifted and jiggled gently with the movement, impossible to ignore.
"Raizen," she said quietly, voice sweet and a little shy. "Let's go to our room."
Raizen's cheeks flushed pink. He swallowed once, twice.
"O-of course, Yuri," he managed, standing up so fast his chair scraped loudly.
Kametsu gave him a knowing elbow as he passed. "Don't mess this up, partner. She's a keeper."
Raizen shot him a half-glare, half-grin, then followed Yuri out of the classroom.
Her skirt hugged her thick thighs and round ass perfectly, swaying with each step. Raizen tried—failed—not to stare.
The hallway felt longer than usual.
Yuri glanced back at him, small smile playing on her lips. "Nervous?"
Raizen rubbed the back of his neck. "A little. You?"
She laughed softly, breasts bouncing lightly with the sound. "A lot. But… I'm glad it's you."
Raizen's blush deepened, but a real smile broke through.
"Yeah," he said, quieter. "Me too."
They disappeared down the corridor.
