Sensei (Kimetsu No Yaiba)

11

She finally saw Tanjirou and Nezuko together, with another nasty presence in her sight. The blood in the demon was even stronger than any other ordinary demon she had encountered, but less than the one she had felt at the train.

She came to a conclusion, that the demon was one of the Upper Moon.

She kept on watching the fight between Tanjirou and the demon, not wanting to intrudes any possible power Tanjirou could activate.

She wanted to monitor the boy. She wanted him to progress his power faster, her previous plan before she intrudes the first time. She was just afraid, and realized something. She knew he was an exceptional boy. She believed in him.

However, her face changed, becoming more restless and in urgency. The image of Tanjirou being gravely beaten made her wanted to enter the battle. Her body itching to help the poor boy getting attack one after another.

The moment she wanted to intrudes again, she sensed something from Tanjirou. His aura changed and she almost lost her breath. Her aura reminded her of someone from the past, someone that played the biggest part of her life. Could he possibly, already reaching that stage ? she thought.

She thought too soon. She saw something snapped within him and he fell onto the roof as he collapsed. She clicked her tongue, panicking. Tanjirou range of using it was still limited. It was understandable, it was the first time he activated the power.

"Nezuko !" Sensei shouted in urgency when she saw Nezuko came to aid for her brother. She jumped towards them when the Upper Moon swung her sash towards Nezuko, slicing her to pieces.

Sensei sent a kick towards the female demon in the air, but the latter was quick to jump from the place as she sensed another threat coming her way. She looked up to Sensei as soon as she landed ground, and her head pounds. She held her head with her jaw clenched. She shoot a painful glare towards sensei who landed a few feet in front of her with her revealing kimono and long, dark-red hair.

Images started flashed before her eyes, a red eyed female smiling vibrantly under a shining moonlight, flapping her hand in the air as if calling her to come to her.

'Whose image is this ?" she cursed under her breath as her image replaced with a firm look of Sensei, her eyes were an empty black orbs.

"Who the hell are you woman ? You smell nasty." She taunted with her own nasty smirk. Her eyes then avertedto Nezuko who were standing up from the fall, dropping some rubbles from her.

"It's a mistake to take your eyes off me !"

The female demon was sent a good metres away to the back from the powerful kick Sensei gave her. She sucked in a good amount of breath as she regained her composure. The kick Sensei landed on her abdomen took her breath completely out of her.

The female was dangerous, the demon thought. She did not know who was the red haired female, but she knew if she don't do anything, she could get killed.

"Don't stand so calm, woman ! I'll slice you to pieces !" She began to lose his cool, sending a couple of her sash to slice Sensei, but the latter jumped from the attacks and towards the demon, swinging her leg straight to her head. The demon fast enough to bend her back to avoid the kick, her face scream urgency.

"You persistent- !" she used her sharp claws to claw Sensei but she caught the demon's wrist before cupping her lower face, clenching her jaw tight. Her orbs dilated at the strength Sensei had, the red-haired mocking her with her empty orbs.

"I wonder how your face look like, little girl." Sensei taunted her with a smirk, but she quickly jumped from there when she sensed the familiar sashed coming towards her again. As she was in the air, she saw Nezuko charging towards the demon, her physical being an adult.

'This is no good.' Sensei thought when she watched Nezuko continuously growing stronger from the rooftop. The bloodlust she was bearing was not a real Nezuko. Sensei noticed how Nezuko progressively regenerated herself, parred to one of that Upper Moon.

Nezuko did numbers on the demon. It better that way. Sensei couldn't do anything without her blade. The only one who was able to kill the demon was Tanjirou at the moment, and she noticed him already awake.

Tanjirou quickly went to find Nezuko and she calmed herself, knowing the siblings can take care of each other.
