Sanemi is the strictest teacher, and he's the math teacher. The hardest subject in High School.

Question

So you know his students dread going to his class.
Some pray, others just wish death, others just cry silently before his class.
Just one look from him makes a whole class silent.
If he goes in a different class to talk to a teacher, the class is loud, he comes in and its quiet. SILENT. Even other teachers are a bit afraid of him.
Most substitutes call him when they cant control a class.
It's crazy.
I mean the guy wears white shirt under an unbuttoned black jacket and pants, with a green-tinted version of the Demon Slayer Corps uniform's haori, and he has his top unbutton so you can kinda see his chest, it has to massive scars like an x. Not only that, his eyes are scary.. bloodshot, he has scars across his face and all over his arms... they're all massively jagged and scary!.. even his younger brother Genya has one across his face. But just one.
Nobody knows how they got them, nobody is brave enough to ask Sanemi but Genya? he just nervously laughed and said it was an accident when they were younger.
But to be honest, it isn't THAT bad.
Despite his class being hard, he actually explains really good, he even gives jollyranchers if you pass a test. Which is kinda rare.
And on a good day, he'll only give a couple assignments and if you're done, you can be on your phone or talk SILENTLY.

But there's this girl. She's a junior, shes sky and nervous all the time, she's tired all the time and mostly keeps to herself. But she's VERY smart in math. Every since she came to this school as a freshmen, shes passed and has gotten amazing grades in his class. He uses her as an example, she;s so good he doesn't even call on her, knowing she gets anxiety and stutters when he used to.
He's much nicer to her, if he's yelling at the class, he directs it to the whole class EXCEPT her.
And if shes missing an assignment? He gives her more time and doesn't take points off.
But he doesn't use her as an example all the time, and others don't know that he gives her extra time and stuff because he doesn't want her to feel like a teachers pet, and he doesn't want others to treat her like she's one.
He also knows her situation a little, her mother contacted him, saying that her and her husband are getting a divorce and have split custody, so she might be late on assignments or be more tired than usual.
So today, she comes to his class late, she has her head down, letting her long hair cover her face. Sanemi tells her to wait outside, that he needs to talk to her, she goes back outside and he tells the class to finish late or other assignments.
When he goes outside, he asks her softly to look up, she hesitates but looks up at him. She has a black eye, and small cuts, she looks tired and like she got done crying.
He examines her face for a couple seconds, then asks her who shes with currently. Her dad.
He nods once, asks her if she wants to talk more after class so they can speak in his class.
She nodded.
He allowed her to go back in and she sat in her seat, that's all the way in the back.
After class.. they speak.
He waits for her to talk, telling her to take her time.. She eventually talks in her quiet but hearable voice. Saying that shes currently with her dad.. that he did this, telling him that that reason her mother divorced him was because he found out that he would hurt her behind her back, but the court knew her father and gave in his favor to have split custody, that her mother is working on talking full custody... and she starts crying, telling him how shes afraid and begging him not to tell CPS because his father knows people and he might take her.
He nodded and comforted her throughout the whole time, telling her that he'll try his best to help her and her mother.
She wipes her tears away, asking if she can stay here since its his last class and he has planning, meaning no students. He nods, tells her that she can stay and goes back to his desk to inform her other teacher.
She.. she has never felt so safe..

Answer 1

Sanemi Shinazugawa was known for his intensity in the classroom—a strict math teacher with an air of authority that transformed even the boldest students into timid shadows. The moment he entered the room, the atmosphere shifted. His piercing bloodshot eyes could silence raucous laughter and sharp whispers in a heartbeat. Clad in a stark white shirt that peeked under his unbuttoned black jacket, accompanied by loose-fitting black pants and a green-tinted haori reminiscent of the Demon Slayer Corps uniform, he struck quite the figure. Scars marked his skin like a map of battles fought; they were jagged and deep, each telling a story that no student dared to ask about. Even the teachers at the school had a healthy respect—and perhaps fear—of him.

Today was like any other day, but there was a palpable sense of anxiety that hung heavier in the air. Rumors had spread in whispers about one of his students, a young girl named Kira Tanaka. She was a junior with a reputation for intellect, especially in math. Kira had consistently achieved high grades and was frequently used as a benchmark for the class. However, Kira had always been timid, often retreating behind the curtain of her long, dark hair to shield herself from the world.

Sanemi had noticed the change in Kira. She walked into class late, her shoulders hunched, her head down. He called her out. “Tanaka, outside. We need to talk.” The class murmured as she slipped out, leaving the door ajar. Inevitably, the chatter resumed.

As he walked outside after his lecture, he could see Kira's form silhouetted against the light of the hallway. “Kira,” he said softly, motioning for her to look up.

She hesitated, her gaze hovering on the floor before finally meeting his piercing eyes. The sight that greeted him was troubling—Kira had a black eye and small cuts on her face. The dark rings under her eyes spoke of sleepless nights, and her cheeks were streaked with remnants of tears.

“Kira,” he said, concern thick in his voice. “Who are you currently with?”

“My dad,” she whispered, the tremor in her voice betraying her vulnerability.

He nodded once, his heart sinking at the response. “Do you want to talk more after class? Just us?”

Her eyes searched his, and then she nodded silently, a flicker of relief accompanying the fear etched across her face.

“Alright. You can go back in,” he said, allowing her to re-enter the classroom. He glanced at the students, many of whom were still bustling about with their assignments, before he returned to the chalkboard, feeling an unsettling knot in his stomach.

When the final bell rang, he dismissed the students and closed the door behind them. The chatter faded into the hall, leaving an eerie quiet encompassing the room. Kira sat in her usual spot at the back of the class, her small frame curled up in her seat.

“Take your time,” he offered kindly, taking the seat across from her as she hesitated, biting her lower lip.

“I—” She took a deep breath, her voice barely above a whisper. “I’m with my dad, but...” Her voice faltered, tears welling in her eyes. “He did this to me, sir. I don’t want to go back.”

Sanemi’s heart sank. “Kira, you don’t have to rush. I’m here for you. What happened?”

She wiped at her eyes, hair falling over her face, struggling to gather the words. “My mom... she’s getting a divorce. They split custody, but my dad... He hurts me when my mom isn’t around. Like... like he thinks it’s okay.”

He leaned forward, frustration boiling within him at the injustice this girl was suffering. “Kira, that’s not okay. I want to help you, but I need you to be honest with me about everything.”

Tears flowed freely down her cheeks now. “The court knew he would hurt me behind my mom's back, but he knows people—important people. Please, don’t tell CPS. I’m scared he’ll take me away if he finds out.”

“Shh, Kira. It’s okay. I promise I’ll try my best to help you and your mom. You’re not alone in this,” Sanemi assured her, his usually stern voice softening, the harshness replaced with a warm firmness. He reached out, his hand resting comfortingly on her arm.

She looked up at him, her breath hitching as she wiped her tears away. “Can I... can I stay here? Since it’s your last class? I feel safe here.”

“Of course you can,” he replied without hesitation. He stood to inform the other teachers that he wouldn’t be available for a while. “You can stay as long as you need, Kira.”

He returned to find her still sitting at his desk, visibly more relaxed now that she felt safe. The thought of what was happening to her weighed heavily on him, leaving a seething anger in his chest, but he needed to be her anchor in this storm.

As they spoke further about what was happening, a bond began to form—one forged in understanding and compassion that neither had expected. Kira realized that even behind the stern facade, Sanemi was a teacher who genuinely cared for his students. And for the first time in a long while, she felt a flicker of hope. In this small math classroom, maybe, just maybe, she had found a safe haven.
