"Don't you dare tell Hisashi or anyone else what happened. You hear me, Sensei?" Rei whispered, lifting up her skirt to properly fix her panties, which still had a visible stain of her love juice, before finishing changing into her new uniform.
Her harsh words and sharp tone told Nach that she had indeed fully recovered from her trauma. Still, her hostile attitude toward him—despite the intimacy they had shared—stung his heart a little, but at the same time made his body excited and aroused, with his mind thinking about how much intimacy it would take for Rei to completely forget Hisashi or Takashi and willingly surrender to him.
"And don't even think about blackmailing me," Rei continued, snapping Nach out of his playful, perverted thoughts.
Despite her attempt to intimidate him, Nach could see the glint of fear in Rei's eyes.
That's understandable, I guess, he thought, considering she was probably anxious about another teacher having something on her, especially after what Shido did to her—holding her back a year because her father was investigating Shido's family.
Blackmailing tropes were exciting and arousing when reading them in stories, even for Nach. But despite being a degenerate pervert, he would never do it in real life—not even now, in what he assumed was a dream.
"I won't, of course," he said while closing the zipper of his sports jacket to finish changing into his new fitness clothes.
"I'm a teacher, so I won't do that kind of thing to a student," he continued, patting Rei on the head to ease her worries and reassure her.
Despite all the contradictions in Nach's words—considering everything that happened between them, not to mention that he beat and shot a group of high school boys—Rei decided to trust him, believing everything he did was for her sake.
Seeing her look away, trying to hide her blushing face yet still indulging in the comforting feeling of his hand on her head, Nach couldn't help but feel delighted knowing Rei at least trusted him.
However, his perverted personality flared up again, ruining the moment as he leaned down and whispered into her ear:
"But if you need my help again instead of Hisashi, all you have to do is ask, Rei."
Rei became even more flustered. Her face turned bright red and her body heated up as a pleasurable trembling spread through her.
"Why would I—"
She was about to lash out and shout, but Nach quickly covered her lips—not with his hand, but with a kiss.
"You can't shout like that, or we might attract the undead," Nach said as their lips parted, only to kiss Rei again since she didn't resist nor push him away but clung to him instead.

With Rei and Nach's intimacy coming to an end, the two of them prepared to leave the store, aiming to reach the Onbetsu Bridge before noon.
Nach strapped the axe and sledgehammer to the side straps of the camping backpack before putting all their food and drink items inside, along with the extra two revolvers and his white trunks in a different slot.
He placed the handcuffs, motorcycle keys, and the morning-after pills in the pocket of his jacket. His revolver—with three shots left—was tucked behind his waist, and his bloodstained baseball bat remained in his hand.
Rei, meanwhile, had a new makeshift spear crafted by Nach using a wooden staff and a knife duct-taped onto it, along with her revolver tucked behind her waist with four shots left.
The two of them were ready to go, but as Nach peeked through the curtain covering the open door of the fitting room and scanned the inside of the store for undead or the living…
"They're gone," he whispered, confusing Rei, who was standing behind him, unsure who he was referring to.
"The high school student couple—I mean, I can't see their undead," he continued, looking at the spot in the middle of the store visible from the entrance of the fitting room, where the bitten couple had been having sex earlier.
"Did they perhaps chase someone outside?"
Rei's assumption was reasonable. However, even though he indulged himself in their intimacy earlier, he had still kept his ears sharp, listening outside the fitting room, and Nach didn't hear anyone enter the store or cause a commotion with the undead.
"They might simply be lurking behind the shelves, so be careful, Rei," he whispered as he silently stepped out of the fitting room, sneaking from shelf to shelf with Rei following behind him.
They took the same route they had taken earlier, and as they passed through the tools aisle, they finally spotted the female student.
She had indeed become undead, but something was different about her—something Nach could easily tell as he locked eyes with her.
This one can definitely see us without reacting to sound, he thought—or rather, panicked—as the undead girl rushed at him.
—ROARRR!—
Nach panicked not because the undead girl was clearly seeing him with its eyes, nor because it was the first time he encountered an undead with such a terrifying roar. It was because it was rushing toward him at inhuman speed.
He knew he wouldn't make it in time to draw his revolver and shoot the undead, nor gather enough strength to unleash a swing powerful enough to kill with a single blow from his baseball bat.
Evading was already too late as well—his panic delayed his instincts.
His only choice was to block its jaws as the undead lunged at him, aiming to bite his neck.
Nach gripped his baseball bat at both ends and shoved it into the undead's mouth to avoid getting bitten. However, its jaws weren't his only problem.
—BAMM!—
The moment the undead tackled him, his feet left the floor and he was slammed onto the ground, sliding several meters away from Rei.
"ARGH!"
The impact of his fall was at least cushioned by the large camping backpack on his back, protecting his head from hitting the floor. So his painful scream didn't come from the fall. It came from the strong grip of the undead on his arms, as if trying to tear them apart while straddling him on the floor and slowly crushing the baseball bat with only the force of its bite.
"Sensei!" Rei shouted, rushing toward him. But Nach knew she didn't have time to help him.
"Don't worry about me!" Nach shouted back, stopping her from approaching.
"Why…?"
"Rei, behind you!"
