By the second class, and even throughout the entire day,

Empty City displayed unprecedented prowess. In his own words, he had an unparalleled talent for teaching!

First, his knowledge of swordsmanship and firearms far exceeded everyone’s expectations—even to a terrifying extent! He analyzed every tactic and technique down to the finest detail. By the end of each lesson, students praised him nonstop, confidently saying their skills would definitely improve.

But whenever this happened, Empty City would remind them that real combat mattered most.

At least, his relationship with the students was steadily improving.

"If the teacher just taught properly, wouldn’t that work too?"

In the school hallway, two girls who’d just returned from lunch happened to meet. The speaker was Cheng Zhihui, class monitor of Grade 2, Class C. She had luxurious silver hair, deep emerald-green eyes that were crystal clear, and snow-white skin. Her tall, elegant figure was wrapped in the uniform—sensual yet dignified. Her relaxed tone radiated sincere praise for Empty City’s performance.

Beside her was a girl who’d somehow retreated behind Cheng Zhihui. Being shorter, Estia could only show her light skirt hem. Yet... her slender back seemed unable to conceal her massive bosom.

Estia’s true identity was a Dairy Maiden—a being created by the negative effects of the Apostle Invasion. If discovered by humans, such creatures faced scorn, death, or imprisonment. Humans feared them. Sadly, that was society’s tragedy.

Estia was a very cute girl, at least in Empty City’s eyes. Her round face had a hint of baby fat but was smooth and beautiful. Her small nose and lips formed a face that sparked fantasies. Her short, flaxen hair fell to her chest, combining with her terrifying D-cup bust into an extremely alluring pose.

"Mhm. The first day was a special case, okay? But you—do you still think I’m a weirdo?"

Suddenly brought up that old joke! Cheng Zhihui immediately stomped her foot but couldn’t find words, ending with a cold snort. Though strong-willed and ladylike, she was still just a young girl.

Empty City chuckled inwardly, a sly smile spreading on his lips. This made Cheng Zhihui even more flustered. But for him, another issue remained: Estia. Since their first meeting, she’d hidden behind Cheng Zhihui like a mouse seeing a cat. Her head would peek out, only to shrink back the moment her eyes met his.

"Sigh..." Empty City sighed helplessly.

Even a thick-skinned girl would sense the tension, let alone Cheng Zhihui. Estia usually listened attentively to his lessons and had stood by him from the start, often helping him out. But during interactions, she’d vanish behind Cheng Zhihui as if fleeing a monster. Had he planted weird ideas in her head back in the infirmary?

After stroking her chin in thought, Cheng Zhihui had a flash of insight. She fixed Empty City with a sharp, forceful gaze—a look that screamed, "Did you do something weird to Estia? If so, I’ll kill you." It made him shudder involuntarily.

"No... well, Miss Cheng Zhihui, could you let me be alone with her for a moment?"

Hearing this, Estia’s eyes clouded with confusion, her gaze drifting aimlessly. She wanted to cry out to Cheng Zhihui for help but couldn’t. Deep down, her heart secretly yearned for this talk.

"I..."

"Mhm... if the teacher wishes."

Cheng Zhihui stared blankly at the girl behind her—who seemed to have made a decision—then watched them walk away.

What exactly happened? This felt like the setup of a youth romantic comedy.

.....

In the afternoon, students either ate together in the cafeteria or shared homemade bento near the school garden. Couples wandered off to cuddle in spots hidden from cameras—it was all quite common. Since their topic was sensitive, both tacitly chose a secluded spot.

That’s right—the sports equipment storage room!

Who exercised in the afternoon? Everyone rested or played! Working out now would harm the body! Here, no one would discover whatever they did!

Thinking about bringing Night Zero here later for some embarrassing play, Empty City’s face flushed slightly.

But this tiny change didn’t escape Estia’s eyes. Still shy from yesterday’s incident, she kept glancing at him, wondering if he cared as much as she did—and why he’d brought her here. When she looked up, she saw his slightly lecherous smile, as if pondering something terrifying, his cheeks tinged red.

Teacher...

She froze mid-step, too scared to approach the open equipment room door. That dark, abyss-like space—if she entered, she might never come out.

Gulp.

She swallowed her heavy feelings.

"What’s wrong, Estia?"

Empty City, snapping out of his fantasy, realized he was still with his student. Opening the storage room door, he found Estia stopped five meters away.

"Um... Teacher."

"What is it?"

He knew she was shy, and after yesterday morning, her wariness was natural.

"You... won’t eat me in there, will you?"

"Eh? Ha——!!"

In the quiet afternoon, at the door of the sports equipment room, Empty City’s helpless wail echoed!
