Protagonist?

"I… I wasn't…" Aimi stuttered.

"It's okay. It would make it easier if everyone knew what to address me as. Instead, I must ask you to get used to it. Thank you, Harue-san."

"th-thank you. You're welcome Hikaru-san." She smiled with a deepened blush. "Are you really okay?"

"Yes. Fortunately, this blood isn't even mine. Why are you here?"

"But I saw something on your face!"

"You saw that?"

Hikaru wondered how much she saw. Did she see the parasite enter his body?

"Yes. By the time I rushed over, it had disappeared! It could still be around!"

"… Not at all. This is awfully hard to explain but I know it won't be back. Trust me."

"It won't come back?" she asked sounding confused.

Hikaru didn't know if she's the superstitious type, but he believes he can convince her that it was some sort of spirit or curse, as they are deeply rooted in Japanese superstition.

He thought that it would be easy to convince her to keep it a secret since she was clearly into him.

"Yes. I don't know if you believe in spirits Harue-san, but-eh?" A strange expression crept upon his face.

"What's wrong!" Aimi asked worriedly.

"I don't know…"

He started getting dizzy and salivated a lot. It felt like motion sickness.

"I think I'm feeling very starved…" He said as his vision blurred.

"Geeeeh"

He heaved onto the floor.

After sudden nausea went away, he saw that there was clear viscous vomit on the floor.

"I-I'll call the ambulance after all!!" she snapped and brought out her phone.

Hikaru felt something move inside of him.

"Gahhhh!"

Tentacles ripped through his shirt and twisted themselves around her. Her shock made her drop the phone.

"Ahhhhh!" She screamed. She struggled to pull the tentacles off, but it was too difficult just using her hands.

"AGH! Stop!" Hikaru yelled as he tugged against his tentacles with his hands.

"Hikaru!! Please let me go!"

"I can't it's not me! It's the thing! I can't control it!"

Aimi grabbed hold of the kitchen bench as it was reeling her in like a fish.

"AGHHHHH" He screamed in pain.

Aimi made a slash at one of his tentacles with a knife she took from the knife block. It felt like another limb of his were being cut off from him.

"You BITCH! You're HURTING ME!" Hikaru shouted furiously.

Aimi paused swinging the knife and looked at him desperately with dribbling tears and snot.

"I'M SORRY BUT I DON'T WANT TO DIE! PLEASE SAVE ME HIKARU!"

'What am I thinking?' He thought.

The tentacles are a part of him now. He might bleed out to death if she kept hacking at him. If she gets away, everyone will go hunt him down.

There's no need to keep his facade anymore. Besides, he felt like he was going to starve to death. He needed to kill Aimi.

She slashed repeatedly at one of his tentacles in left and right swipes until it dropped to the ground.

The rest of his tentacles subconsciously let go of her from the pain of amputation.

She ran to the front door and turned the door handle again and again, but it wouldn't open.

Then she unlocked the door and opened it but then it was pushed shut by a tentacle beside her.

Hikaru then actively wrapped her waist with his tentacles and flung her towards him.

He made a ball with his fists and swung at her face.

Her head shot back, and his fridge made a clanging sound.

She looked back at him in shock and when she screamed, he could see a tooth missing. The tooth had flown out and bounced off the fridge.

Hikaru smacked her screaming face again and she fell backwards but the tentacles wouldn't let her upper body fall onto the tiles. Instead, her feet held the ground and she hanged backwards with the tentacles around her like a safety harness.

The tentacles pulled her upper body back up when it sensed that she had stopped struggling but when she rose, she threw her knife-wielding arm at Hikaru.

As she took advantage of his momentum and attacked unexpectedly, she was moving too fast for any normal person to dodge. However, Hikaru swiftly reacted and caught the blade with his bare hand as it cut his palm.

He ignored the pain and clutched harder onto the blade, then he forced the tip of the knife backwards and plunged it into her neck.

She froze with widened eyes as she wallowed in the pain.

Hikaru pulled the knife and threw it away. Blood gushed out of her neck.

He grabbed her by the back of her head and then shoved her into his chest with the tentacles.

Blood sprayed all over his body. Initially, blood spilled onto the floor but then stopped when his chest seemed to merge with her wound. The blood was now being sucked into Hikaru with a squelching sound at every pump.

When he felt the dizziness go away, he tried pulling her head off, but her body was stuck to him like hot glue.

When he looked closely, Hikaru could see that her body was slowly sinking into him.

*Bang Bang*

Someone violently knocked at his front door.

It couldn't have been his father returning home because he would be returning late tonight. If it was him, he would have just opened it with a key.

So, who could it be?

Hikaru looked at Aimi's body which seemed to be going inside him headfirst. It couldn't have been more than a minute, and someone was already knocking on his door.

It can't be a coincidence.

Could it be a neighbour who heard the screams and came over to investigate?

Hikaru walked over to the door to use the peak hole but realised Aimi's body was in the way.

*Bang Bang*

"Hello? It's an emergency!"

It sounded like a boy around his age was calling from behind the door.

Hikaru wondered how he could move Aimi's body aside and then suddenly the flesh on his body began shifting and Aimi's body was moved around to his back.

He was stunned.
