"Don't worry. This man absolutely cannot escape. My improved attack method has completely rectified the flaw of the previous 'first-strike kill' condition."
"Furthermore, the flow of time inside the classroom is synchronized with reality. The subject won't suffer any physical harm while inside. Starvation is only a matter of time."
The Teacher Devil reached up and adjusted the black-framed glasses perched on her nose, then gave a satisfied pat to her chest—which was prominently exposed and noticeably full. As her hand moved, the soft, jiggling weight swayed gently from side to side, possessing a palpable, resilient bounce.
"Hmm, good. You've done well."
Kishibe nodded, her eyes fixed on Renji within the white-paper space. Then, she pinched a corner of the paper between her fingers, flicked her wrist, and sent it sailing through the air like a thrown dart.
The paper arced, spinning as it flew, before finally fluttering down to settle on the carpet a short distance away.
The Teacher Devil looked puzzled, unsure why Kishibe would suddenly act so playfully. "What's wrong? Why not keep holding it? Why throw it away?"
"He's about to break out."
As she spoke, from the distant sheet of paper, Renji's two arms had already stretched out, searching wildly for leverage. His hands soon found the carpet on either side.
Bracing his palms against the floor, Renji pushed with all his might and leaped free from the paper space, landing steadily on his feet.
"Phew… That was close. Almost didn't make it out."
"Wh-… What?! How is this possible?! Impossible! How did you get out?!"
The Teacher Devil's face was a mask of utter disbelief. Seeing it was her, and knowing her ability, Renji chose not to respond.
"I created a perfect classroom environment! A compassionate teacher! And based on the intel, I even created a cute, mischievous little sister! Didn't the intel say you adored your sister?!"
When Renji heard the Teacher Devil mention the intel about him having a sister, he vaguely recalled mentioning it somewhere—was it during patrol with Denji, muttering to himself while reminiscing? He couldn't quite remember.
Though Renji loved his sister deeply, he was certain he had never disclosed how she addressed him.
His sister didn't call him 'Onii-chan' or 'Stupid Big Brother'—those affectionate terms. She called him directly by his given name.
"Hey, Renji."
"Renji, what are you doing? Where are my snacks?! Did you eat them, you jerk?!"
"Renji, you're bullying me again! Just you wait! Waaah! When Mom gets back, I'm telling her you bullied me! Waaah…"
How to put it…
He could only say his sister was in high school, and Renji felt she'd hit that… chuunibyou rebellious phase where she thought calling him 'Brother' was embarrassing.
So, the moment he encountered the mischievous little sister crafted by the Teacher Devil inside the space, Renji instantly recognized her as a fake and realized he'd walked into a trap.
Seeing Renji remain silent, the Teacher Devil's expression twisted with fury. She was like a teacher whose wrong answer had been pointed out by a student, then talked back to—suddenly stripped of all authority at the lectern, left with no way to save face.
That complex mix of humiliation and rage solidified on her features.
She glared venomously at Renji, her red lips trembling slightly with indignation. And now, as a teacher, she needed to do two things to reclaim her dignity.
Step one: verbally discipline the student.
"Even if you could spot those inconsistencies! What about my improved questions?! I designed every one with counter-intuition in mind! A woman's labia! A woman's womb! The capacity of a woman's uterus! How did you answer those?!"
Renji thought of Himeno. All those questions had answers written on her body. He had explored every one with his own length: the depth of her entrance, the dimensions of her womb—he could calculate them based on his own measurements.
But he still didn't answer the Teacher Devil.
"Hey! You bastard! Idiot! I'm asking you! Why aren't you speaking?! Huh?!"
Renji's focus remained primarily on Kishibe, only sparing the Teacher Devil a brief glance.
"Hey! Talk! How dare you ignore your teacher?! I asked you! How did you get out?! Is this another one of your special 'manly' abilities?! What power did you use?! Was it your dick again?!"
Second Step: Discipline the Student.
Seeing Renji remain utterly silent, ignoring her completely, the Teacher Devil tightened her grip on the ruler. Fury etched across her features as she advanced toward him step by deliberate step.
As the distance closed, Renji finally turned his gaze to her.
The Teacher Devil was dressed as before: a proper teacher's blazer over a crisp white shirt, several buttons at her chest undone, revealing the smooth, full swell of her breasts—a deliberately tantalizing display. The pressing together of her ample curves formed a deep, shadowed cleavage that was undeniably provocative.
Her lower half was clad in a tight, impossibly short black skirt that clung to the generous curve of her hips. Her slender legs were sheathed in a pair of sheer, black stockings that shimmered faintly with each step, the hint of flesh beneath the fabric making them all the more alluring.
The dull, rhythmic thump… thump… thump of her black heels against the carpet grew louder as she closed in.
"As a student! How dare you ignore your teacher's questions! It seems you need to be taught a proper lesson! Hold out your hand! This teacher is going to give you a good smacking!"
Seeing Renji make no move to comply, the Teacher Devil tucked her ruler away and raised her hand, intending to slap him—to make him understand the price of disrespect.
Renji activated the Future Devil's ability. His head tilted a fraction to the side, and the aggressive slap whistled harmlessly past his cheek.
In the same fluid motion, his left hand shot out, pressing firmly against the Teacher Devil's right cheek. Then, with a sudden, explosive surge of force, he shoved—hard—to the left.
An irresistible power erupted from his palm. The Teacher Devil had no time to resist. Her body was flung sideways, crashing into the left wall with a tremendous BOOM.
Dust billowed; debris scattered. As the cloud settled, Renji saw that the wall had been broken clean through, a gaping hole torn open by the impact.
And the Teacher Devil was now wedged in that opening, her upper body thrust through to the other side, her waist perfectly caught in the breach. Only her lower half remained visible in the room—exposed and vulnerable.
Wall-sexed.
The pose was unmistakable.
The Teacher Devil, being a Devil, possessed a formidable physique. Even in this state, she showed no obvious external injuries. Her lower body, facing Renji, swayed slightly from the residual force, the tight skirt doing little to hide the movement of her ample rear.
—Splurt!!!
—Splurt!!!
...
The moment Renji's left hand made contact with the Teacher Devil's cheek, his special effect against females triggered.
A powerful surge shuddered through her core. A hot rush gushed forth, soaking the front of her skirt in an instant dark patch. Renji could see the fabric grow heavy and wet. But a significant amount also streamed down the inside of her thighs, slicking the sheer black stockings, dripping from her high heels, and pooling on the carpet below.
In the corridor, her legs twitched uncontrollably, shifting outward (<<) and then inward (>>).
Inside the room, her upper body trembled, her face flushed a deep crimson. Muffled, whimpering gasps escaped her lips.

Renji turned his gaze back to Kishibe. She raised her hands slowly, palms open in a gesture of surrender.
"Wait. Wait. Can we… talk for a moment? This conversation stays between us."
"Hmm? What is there to talk about? Let me be clear—I'm not cutting it off for you. Don't even think about it. It's not happening."
Kishibe's expression remained blank. She lowered her hands slightly.
"Hear me out first. You might change your mind. I've never harbored ill will toward you. After all, you are the only man in this world. That makes you… a very significant existence."
Renji stayed silent, so Kishibe gestured toward the Teacher Devil, who was still wedged in the wall, shuddering through wave after wave of involuntary release.
[Ding~ Detected Kishibe's helpless emotional state. System rewards 10 points.]
"She's useless now. If you want her, I'll give her to you as a gesture of goodwill. Once I leave, you can do whatever you like with her. When you're finished, she'll revert to a lump of flesh you can carry with you. Summon her anytime, anywhere, if the need arises."
The Clothesline Pole in Renji's hand dissolved into spiritual particles and vanished. He kept his eyes on Kishibe.
"So what is it you want to say? Say it now, and be quick about it."
