The King Of Beasts

Yasei Omos' Cursed Technique was the same as Kashimo Hajimes', Mythical Beast Amber. However, his electrified Cursed Energy was used to power his Technique causing it to take a vastly different form, which resulted in a one-time use Cursed Technique. Omo who lacked this Cursed Energy used Mythical Beast Amber in its true unaltered form.

Instead of reconstructing the user's body into electricity, Omo's version only transformed it, to take a shape that went beyond normal human capabilities. Furthermore, by using a binding vow to limit its use to 5 minutes, Omo drastically increased its power. This version of Mythic Beast Amber was far weaker than its predecessor, however it was still powerful nonetheless.

Thanks to the beast-like appearance that he gained when this transformation was in use, Yasei Omo had gained the title of the king of beasts!

As he roared loudly into the sky, he dashed towards Matsu, way faster than before. Matsu who was freaking out because of his beast-like appearance raised both his arms to block the attack.

As he did, Omo slashed away at his arm somehow scratching through, his armoured skin, causing light bleeding. As Matsu tried to back away from the man, Omo grabbed onto the bleed arm, and with great strength, threw Matsu into a nearby wall.

Matsu said, "You can cut through my diamond-hard skin!?!"

Omo, not bothering to respond, jumped towards him with great strength slamming him through the wall, into another building.

As Matsu stood up, his Greyscales, began to crack and fall apart from the place, where he had been attacked. Matsu shouted at him, "Impossible! My steely skin is invincible!"

The two then faced off against each other once again before charging in for their last attack. 

Matsu threw a left hook this time intending to knock Omo out in one hit. However, Omo dodges and then with his claw, severs the arm from Matsus's body. As his blood sprayed out, Matsu screamed, "WHAT HAVE YOU DONE??"

Omo then with his left arm grabs Matsu's face, before picking him up and slamming it into the ground, knocking him out.

As Omo stood over his unconscious body he said, "The slice was clean, if you're lucky you can get it reattached."

As he turned around to look at the tower, he saw a multitude of tree roots, bursting out of the tower's highest floor, while Kenji was dangling at the end of one. He then shouts, "Kenji!?!"

A couple of minutes earlier

Thinking that most of their forces would be concentrated at the entrance, Omo volunteered to go distract them, while Taori and Kenji would enter from an emergency underground exit. As Omo split off from the group to go attack the main entrance Taori and Kenji came upon a mysterious, metal door that was etched into the earth.

As Kenji forced the door open, it revealed an infinite darkness to peered into the abyss.

As Kenji walked inside, Taori stayed behind. He then asked her, "What's wrong?"

Taori replied, "There is something that I need to do. Do you mind going ahead of me?"

Thinking back to her story Kenji asks her, "If you're worried about him I can stay with you?"

"That won't be necessary. I don't want to hold you back," she responded.

As Kenji walked into the darkness, Taori slammed the doors shut behind him. She then said, "You have been watching us ever since we left that hospital haven't you? It's time we finished this Mitsuki."

As she finished, a figure coated in black while wearing a white mask appeared. Mitsuki then said, "Im sorry sister but I'm really going to kill you this time.", he said as a pair of wolverine-like claws, emerged from his knuckles.

As she sighed she said, "Your stubbornness was always your greatest strength and weakness."

As Taori opened up her simple domain, while preparing to draw her sword Mitsuki disappeared into the night.

Mitsukis' Cursed Technique was shadow stalker. It allowed him to merge his physical body with darkness, allowing him to appear anywhere that darkness was present. In that state he had near-limitless speed, however, he couldn't do any damage until his Technique was deactivated.

As he vanished he manoeuvred around Taori, so fast that he began untraceable even to her. As he did so he said, "You could only ever sense, me when I stood still, but it's another story when I move around as fast as I do now!"

As Mitsuki dashed towards her from behind, he entered her simple domain. Taori drew her sword, instantly slashing him, however the attack was ineffective. He then manifested back his physical body for a split second, giving, Taori a shallow cut to her right side which bled a little. As he did, he instantly went back to Jumping across a variety of trees while Taori opened her simple domain once more.

He then said while taunting her, "Your smiple domain is really impressive. However, it can't detect the exact millisecond that I turn into a physical being again. Using your Cursed Technique won't help you either."

As Taori struggled to keep up with his movements, Mitsuki then returned to attack her once again. As he entered her simple domain, Taori immediately slashed away at Mitsuki cleanly, however the attack phases through him. Just before, he manifests his physical body, Taori summons her Cursed Technique to try and cut him as he strikes him back.

This fails as Mitsuki jumps back. He then says, "That won't work Taori. You release a ton of Cursed Energy just before your clone takes its form. Any seasoned Sorcerer can easily avoid it!"

Mitsuki then transformed, into a shadow once again, manoeuvring around her.

Then shockingly she disabled her simple domain while preparing to draw her Katana.

Seeing the opportunity to kill her in one blow Mitsuki lashes out at Mitsuki while aiming one of his claws, at Taoris throat. In the last second just as he physically manifested, Taori said,

"Yama style: piercing death."

The second Taori drew her blade, Mitsuki felt a terrifying chill paralyse him. As he struggled to turn back into a shadow the fight had ended. Taori drawing upon her white blade pierce her brother's heart, dyeing the sword crimson.

As Mitsukis blood, sprayed out of his body, like a water hose being turned on, Taori said gently as a tear streaked down her face, "Im sorry that I had to do this. If I went back to save you back then, maybe we wouldn't have turned out like this."

In that moment Taori used her killing intent to paralyse Mitsuki, in between the moments that he made himself physical to attack. As Mitsuki collapsed to the ground, his blood stained the blades of grass on the floor eventually creating a pool of blood.

As he reached his hand out he said while crying, "Sister... it hurts... help..."

As he struggled to speak, his voice grew weaker and weaker. Until his hand dropped to the ground. 

As she saw her brother's cries for help she dropped to her knees, thinking that this all could have been avoided if only she hadn't taken, the director's offer back then. She then shouts while looking at the tower, "BOTAN, I'LL KILL YOU!"
