AN: This chapter took a while, I work on this when i get writers block.

The group of students felt a shiver run down their spines as the eerie silence was broken by the haunting voice. It was a voice that sounded eerily familiar to Izuku.

"Izuku... my little hero," the voice crooned, sending a chill through the air. It was a voice that bore a striking resemblance to Izuku's own father, Hisashi Midoriya, whom he hadn't seen or heard from in years. Izuku's eyes widened with shock, and he slowly moved away from the door, his gaze scanning the door. The others exchanged worried glances, but they remained vigilant, ready to protect their friend.

Izuku's heart raced as he tried to comprehend the impossible. His father had disappeared without a trace when he was just a child, leaving behind a void that had haunted him ever since. The voice continued, its sinister sweetness filling the room.

"Come closer, my little hero," it beckoned, the words dripping with an unnatural charm that was both enticing and terrifying. It emanated from the door.

Todoroki, always the one to keep his cool, stepped forward cautiously. "Izuku, are you sure that's your father's voice?" he asked, concern etched across his face.

Izuku nodded, his voice barely a whisper. "I'm certain, Shoto. It's him."

Bakugo, never one to back down from a fight, clenched his fists. "If that's really your old man, then what the hell is he doing here?"

Before anyone could respond, my head starting moving in Jiro's arms. Panic gripped them as tendrils shoot out of my head. The haunting voice whispered, "Izuku, my son, I've missed you so much. Come to me." The door smashes open revealing a impenetrable darkness, as my head jumps out of Jiro's arms into the darkness.

"Mr. Tanaka!" Jiro yells, chasing after my head but being caught by Izuku.

Izuku's heartache clashed with his fear. He held onto Jiro tighter, unable to resist the overwhelming allure of his father's voice. His friends tightened their circle, realizing that something sinister was at play.

Todoroki summoned a small flame, revealing Mr. Tanaka standing in the doorway walking out with a limp as it seems like his body is putting itself back together.

The group of students watched in shock as Mr. Tanaka's body slowly reformed itself before their eyes. Hisashi's voice continued to beckon, echoing through the dark abyss as their teacher walks out.

"Izuku, my son, it's been too long. Don't you want to see your father again?" Hisashi's voice taunted, its enchanting melody pulling at Izuku's heartstrings.

Izuku's inner turmoil was tearing him apart. On one hand, the longing to reunite with his father, who had vanished from his life so mysteriously, was overwhelming. On the other, the chilling circumstances and the eerie transformation of their teacher filled him with dread.

Todoroki's flame illuminated the doorway, casting long shadows that danced ominously. Bakugo's hands crackled with explosive potential, ready to unleash his fury at any moment. The group knew they couldn't trust the voice or the darkness that had consumed their teacher.

Todoroki stepped forward again, his icy resolve cutting through the tension. "Izuku, we can't be sure this is your father. Whatever it is, it's not right. We need to find out what's happening here."

Izuku nodded, tears glistening in his eyes. He loosened his grip on Jiro, who was still struggling to reach for Mr. Tanaka's form. Together, they took cautious steps away from the open doorway, their gazes locked on the darkness.

Bakugo clenched his fists even harder, his determination unwavering. "We'll get to the bottom of this, Deku. No matter what."

The group retreated, slowly putting distance between themselves and the doorway. As they did, the haunting voice grew fainter, its sinister charm losing its grip on their hearts. But the questions remained, and the fear lingered.

What had happened to Mr. Tanaka? Was this truly Hisashi Midoriya's voice, or was it some malevolent force using his image to manipulate them? And most importantly, what secrets lay hidden in the impenetrable darkness beyond that door?

With their resolve steeled, the group of students knew they had to uncover the truth and face whatever horrors awaited them in the shadows. They were determined to protect their friend and put an end to the unsettling mystery that had enveloped them all.

AN: I hope this turned out well. Horror has never been something I write so i hope it went well.
