153 Chapter 153: Promise

He guffawed, "Lord, I can imagine how ugly his expression has become"

He looked at Hazel, licking his lips slowly. He was thrilled upon glancing at the woman in front of him. 

When everyone heard that a mere human managed to kill one of the strongest generals, they all wanted to come to check it out but they were stopped by that guy!

As the silver-haired demon was preparing for the exciting battle, Hazel, on the other hand, was shocked beyond the point.

'He wanted to battle with you badly that he gave me the task to handle the academy...'

His words rung in her mind that slowly her expression cracked. Her hands trembled when she thought of what her kingdom was going through. 

Her eyes widened when an image appeared in her mind.

'Usui...'

Thinking about the people she sent over to her kingdom, her expression turned to worse. No wonder she was very unease from the very beginning!

"I wonder how our general is faring at your kingdom"

Hazel knitted her brows when she thought of that stubborn guy. She was sure he would do everything to keep up his promise.

Promise!

Her eyes widened when she remembered what he said.

'He would protect the kingdom by all cost...even with his life'

Hazel's hand trembled at that thought. She finally acknowledged that he had a place in her heart. Would she lose him like her brother? 

Hell no! she would go to the depths of hell if she had to bring him back. 

Jinha looked at Hazel, who was shaking in fear. He wondered when she would fully let go of the past.

He looked at Hazel and said, "He would be fine, Freya"

Hazel turned around to him with a pale expression. 

"Trust me... he is not that weak!"

Hazel inhaled deeply before opening her eyes and smile at him.

'That's right... he is the strongest guy in his kingdom.'

Jinha added, "We could go over once you finish this battle" 

Hazel nodded before turning to look at the demon calmly. 

'Right! First things first'

She lifted her dagger, pointing the demon. The dagger glinted in the moonlight making the demon smile evilly. Soon, sounds of battle reverberated inside the academy leaving the students, who were watching, speechless.

....

Crystal Kingdom 

Usui moved his body before he knew and appeared before the demon instantly. He struck Sirius with his sword before pulling Stella away from the demon. 

Sirius chuckled as he glanced at Usui amusedly.

Usui gestured the space around him with his fingers making the space around the demon constrict him inside a cube. He sighed before turning to Stella and said, "Leave this to me and help the rest."

Stella shook her head with red eyes as she said, "No... I want to kill him."

Usui looked at her worriedly before turning towards the demon who was using his vines to bang against the space around him. 

He knew that if he tried to forbid Stella then she would hate him for the rest of her life. So he sighed and nodded his head. 

"Don't ignore me, guys"

He looked at his brother who joined him, smiling at Usui. 

Usui just shook his head as he was troubled over another matter. This bloody sword has been screaming inside his mind almost making him go crazy.

He found it weird for Black Thunder to be excited to fight against the demon. But he gave in without much thought.

As long as it could make him victorious, he didn't care much.

Usui frowned when he saw cracks appear on the cube he had conjured quickly to trap him. Before it was one strike away from shattering completely, he readied himself to strike the demon. 

As soon as the cube shattered, Usui leaped forward with his sword towards Sirius while Zelal mustered the earth beneath him to follow his will.

Sirius smirked as he used his vines to battle against Usui. His eyebrows rose when he felt the earth beneath him shot upwards. Sirius looked at Zelal who was standing on top of a rock as he controlled the earth.

Sirius stopped the earth beneath him with his vines as he used the rest to battle Usui. Seeing that the demon stopped his attack, Zelal pursed his lips and willed the earth to form into a huge boulder.

Usui furrowed his brows when he was blocked by his vines. Even though he chopped off the vines, it grew once more making it impossible for him to land his attack. 

He heard his brother shout and moved out of the way, just in time to see a huge boulder thrown at Sirius. Usui quickly glanced at Stella who nodded.

Sirius broke through the boulder into pieces, with his vines piercing right through its center. He raised his eyebrows when he saw the holy princess strike at him making him scoff, "Do you think I would fall for the same trick twice?"

He controlled his vines to attack Stella but when his vines raced towards her, he saw Stella twist her body and smirk.

"Nope... I only wanted to distract you"

Sirius frowned at her statement but his eyes widened when he felt a force behind him. His back was exposed!

He turned around quickly but was too late to dodge his attack.

Sirius laughed, "You won't be able to wound me" but then his laugh fell short when he felt the pain. He glanced down to his chest and saw his wound not healing. 

He looked at the sword in horror and saw the white aura around the blade. He turned to the holy princess who smirked, "I might be weak but I still have a few tricks in my sleeve"

Gritting his teeth, Sirius moved back, glaring at the three annoying people. He was furious now, glaring at the holy princess. 

He yelled before he shot straight towards Stella but was blocked by Usui. Sirius disregarded everything as he swiped his claws against the sword. The force of his swipe made the earth beneath them flatten the houses.

Usui was shoved backward but when he raised his finger to control the space, he saw the vines coming at him. Widening his eyes, Usui dodged his attacks but the vines were too fast for him that some pierced his hand and legs.

Sirius noticed Zelal's movements from the corner of his eyes and directed his vines to attack him. Zelal conjured an earth wall, out of nowhere, to shield him but to his horror, the vines broke through his wall, attacking him.

Stella shouted, "Zel"

She wanted to help him but before she could move, she felt the vines wind around her, squeezing her tightly. She bit her lips as she glanced down at the vines entrapping her hands.

Her eyes widened when she saw Sirius appear before her, with his eyes burning in anger. 

"I have always hated your kind. Now, I will send you to accompany your parents in heaven"

But before he could raise his hands, he felt the changes in the space around him making him grit his teeth. He turned around and saw Usui heaving as he stood before him, with his arms and legs bleeding.

Sweat trickled down Usui as he manipulated the space around Sirius. When Sirius turned to attack Usui, he saw his attacks vanish into thin air and appear elsewhere. 

Sirius gritted his teeth as he spat hatefully, "This is why I hate Formation masters"

Usui focused on diverting his attacks while at the same time, attacking the demon. But his focus was disrupted by the sudden cry of Stella. His eyes drifted towards her and saw her cough blood. 

Seeing him distracted, the demon vanished and appeared before Usui making Zelal cry out.

"Brother!"

Sirius slammed Usui with his vines making the latter descend towards the ground like a meteor. Zelal hurriedly willed the earth beneath to cushion his fall but was cut short when numerous vines attacked him.

"Tch... annoyance"

He heard the demon curse and turn towards his sister. Zelal watched as the demon turn towards his sister as he was falling to the ground.  

Usui groaned slightly before opening his eyes slowly. His eyes widened when he saw his brother falling while his sister was entrapped in a tight grip.

He saw the ruins around him and how the soldiers were slowly dwindling. On seeing that everything was slowly getting destroyed, he felt aggravated.

Would he not be able to keep his promise? 

Her happy face appeared in his mind making his heart wince. He didn't want her to cry anymore. He didn't want her to be in the darkness again. 

But it looked like he was going to lose his life here without fulfilling her promise.

What should he do? 

The demon didn't give heed to others as he wanted Hazel which was the reason why he was taking things slow, waiting for her to appear.

But Usui didn't want that Hazel to appear here.

"Stella!!! "

Zelal's cry broke Usui from his stupor making him look at her. His face paled when he saw the demon's claws sticking out of her body. Sirius withdrew his claws, splashing her blood towards the ground. 

Usui felt something wet on his face and touched it to see that it was her blood.

His sister's blood!!

His blood boiled in anger but he couldn't move his legs. He looked at Stella who was falling towards the ground and willed his body to move.

He yelled frustratedly "Damn it" when he saw her body was close to the ground. He saw his brother screaming as he couldn't will the earth to move according to his will.

Suddenly Usui felt his surroundings grow cold when he heard a detached cold voice whisper in his mind, "If you can't do it, then let me take over."
