*Bam*
Swinging his sword again, Yuki destroyed the metal wall separating him from Sister...
*Creakkk*
Just as Yuki advanced, Sister's fingers moved suddenly, and the cuffs binding her began to creak...
*Pum, pum, pum*
Sister's heart and Sephira crystal started pulsing, sending out waves of energy. The moment Yuki entered her range, Sister immediately woke up, her spiritual energy going wild...
Rasiel within her was struggling to come out, responding to the call of its soulmate. It wanted to be with this soulmate, it needed to...
"Ha...haaaa...haaa..."
Her breathing became erratic, and the restraints holding her broke one by one...
*BOMM*
Her spiritual power burst out, and her astral suit began to materialize...
Yuki stopped, recognizing this phenomenon of a soulmate's call. Perhaps because this girl had Rasiel, she was more sensitive to Sister than Tohka, reaching almost the same level as Kurumi. But with Yuki's experience, he no longer let this strange feeling control his mind. He remained calm as Rasiel and his Sephira crystal flashed, sending spiritual waves to Sister.
"Sister, huh? So that's why..."
Yuki smiled upon seeing Sister's astral suit. It resembled that of a nun, but also a sinful nun...
Her astral suit was a semi-transparent ink-colored fabric that fully revealed her erotic figure. Underneath that semi-transparent fabric was black, erotic string lingerie, and much of her skin was exposed.
The neckline of her dress formed the tip of a pen, and the central part of her astral suit had a manga panel pattern. She wore long black lace-up boots and a black veil attached to a pen and duster. There was also a golden cross connected to a string of beads around her dress's waist.
If this girl had a bit more development, she would be every teenager's fantasy...
"Haaa..."
Even so, Yuki couldn't help but sigh. Despite Sister's beautiful and youthful appearance, Yuki knew there was no more room for growth. This girl was an adult in every way, and her small breasts wouldn't grow any more, which was a pity...
*Creakkk...
The metallic glasses covering her eyes shattered, revealing her beautiful ice-blue eyes. When she looked at Yuki, her breathing became even more erratic, like a hungry animal seeing a juicy, delicious prey...
"Rasiel!"
"You won't!"
Before Sister could summon her angel, Yuki moved at high speed. The five fingers of his left hand lit up, and he struck Sister in the stomach...
"Five-Point Seal!"
"Ah!"
The impact made Sister spit saliva, and the oxygen in her lungs was expelled by the blow. At the same time, a strange mark formed on her stomach, sealing all of Sister's spiritual power...
"Ahhh... Ahhh..."
"It's okay, sleep... Trust me, I'll be with you, my soulmate. I'll protect you; no one will hurt you anymore... Sleep, my love..."
Sister didn't want to sleep, but maybe because Yuki held her tenderly from behind, stroking her head gently and whispering sweet words in her ear, she finally closed her eyes as her astral suit disappeared, revealing her body...
"Mission accomplished..."
Carrying Sister in his arms like a princess, Yuki smiled. Darkness covered Sister's body, and Yuki couldn't help but kiss her forehead gently.
This girl had Rasiel, and Rasiel within him shared a deep bond, like two lovers from past lives who finally found each other. Maybe it was because of Yuki's kiss that Sister smiled and snuggled into his arms...
Having completed his objective, Yuki raised a hand, undoing his jutsu. The lions disappeared, his eyes changed, and he slowly rose into the air. A powerful repulsion formed around him...
"Shinra Tensei!"
*BOOOMMMMMM*
The research base was destroyed, obliterated as if struck by the hand of God. Likewise, the trees and everything on the island disappeared, leaving a huge crater as if a meteorite had struck. But that wasn't all. The island itself began to sink and disappear into the sea.
Earlier, Yuki had cut the island in half, and the Rinnegan's repulsion was enough to fracture and sink it. Yuki didn't want to leave any trace of his presence to avoid Kotori's suspicions...
Of course, he also wanted to give DEM a little lesson, a taste of what awaited them. For that, Yuki turned his head to the sky, or rather, beyond the sky...
*Creakkk*
A jet-black skeletal arm began to form around him. In the skeletal hand, an energy sphere formed and was launched at high speed...
-------------
"Marvelous, it's splendid... Is this the power of a male spirit?"
Westcott was pleased and clapped. For him, Yuki destroying this research center wasn't a concern, not even for Sister, his guinea pig, or the warship.
To him, it was a small price to pay to test the powers of this male spirit.
And now that the island had disappeared into the ocean, Westcott was pleased. This new spirit was stronger than the others...
"..."
Ellen beside him didn't speak but watched as the entire island was destroyed, and the humans on it were massacred. There were no survivors; it was a unilateral destruction...
"My dear Ellen, tell me again... Are you sure you can defeat him?"
"..."
Faced with Westcott's question, Ellen remained silent for a few seconds. The strength of this spirit far surpassed the others. Although Princess could almost do what Emperor did, she couldn't do it easily. After all, Emperor faced a fully armed warship and destroyed it with a single blow. He suffered no damage, the mages couldn't stop him, and they were all massacred. Nothing survived.
Emperor's danger level had surpassed rank 'S'. Additionally, after investigating, they discovered that AST was defeated by this spirit. Although AST were all weak mages, they still had the power to repel a spirit, but Emperor was in a completely different league, such a formidable spirit...
"Of course!"
Even so, power wasn't everything. Many factors determined victory, like skills and equipment. Ellen had the strongest equipment from DEM, her Pendragon-type CR, so she didn't fear any spirit.
"I like your confidence, but are you sure? That spirit possesses more than one angel..."
It was unusual for Westcott to doubt Ellen, but he couldn't help it. Emperor showed a lot of versatility in this battle, the beast, and that strange sword. Westcott deduced they were two angels, and neither was weak, especially the strange sword that could split the warship in half.
"Even if he has three angels, I can still defeat him..."
Of course, Ellen had confidence in her abilities and didn't want to appear cowardly in front of Westcott.
"Hm?"
But before Westcott could continue, he noticed something strange. The male spirit was floating in the air with Sister in his arms, but around Emperor, a huge skeletal arm and a ribcage began to form, and energy levels rose...
Then the male spirit looked at them. Westcott and Ellen blinked. This spirit was smiling and staring at them as if his strange heterochromatic eyes were looking through distances...
*Shiiii*
Then something was launched from the skeletal arm, so fast that neither Westcott nor Ellen could see it. Both were confused by such an action until the image began to distort, and the video ended, and Westcott understood...
*KBOOOMMM*
In the outskirts of the world, the satellite orbiting and recording their battle had its 'territory' fractured. Then a black ball hit the satellite, destroying it in the process...
"I'll ask you one last time, Ellen... Can you defeat him?"
Still smiling at the warning screen about the satellite's destruction, Westcott asked. However, this time, Ellen didn't respond. There was no need; they already knew the answer...
