I'm in Morioh, just joined a chat group for cute girls.

Kiana's orange swimsuit was covered in sand, and her snow-white skin was covered with bright red whip marks.

"Stop! What are you doing!?"

Theresa let out a scream and rushed forward without thinking. Her petite body burst with speed disproportionate to her size, trying to get between the two.

"Don't go over there, Headmaster."

An arm steadily stopped her.

Theresa turned around and saw it was Gu Ye. Her eyes reddened with anxiety: "Gu Ye! Let me go! Mei... how could she do this to Kiana! Kiana is about to be beaten to death!"

"Take a good look."

Gu Ye's voice was calm. He didn't let go, but simply gestured for Theresa to look into "Kiana's" eyes. "Are those eyes Kiana's?"

Theresa was startled and looked closely, only to find that Kiana's eyes, which should have been sky blue, were now flashing with an eerie gold, filled with resentment and unwillingness.

"That's... Sirin?"

Theresa's lips trembled slightly. "Why did she become like this? What just happened?"

"Is this really okay?"

Theresa watched Sirin scream in agony as she was whipped. Although she knew it wasn't Kiana, seeing Kiana's body enduring such pain still tugged at her heartstrings. "Her screams... are truly heartbreaking."

"Gu Yejun,"

Mei, who had been standing beside Gu Ye, couldn't help but speak up at this moment. Her voice was filled with worry and self-blame, "Isn't there any way to help Kiana recover quickly?"

"Don't worry."

Gu Ye gently patted Mei's shoulder, giving her a reassuring look. "Kiana is probably just... jealous. Once Sirin can't bear the pain anymore, Kiana's consciousness will naturally come out and take control of the body."

Gu Ye's words seemed like a prophecy.

Under another merciless lash from the Queen of Thunder, Sirin, who was lying on the ground, finally broke down.

With her last ounce of strength, she let out a venomous curse in her heart.

You perverted woman! Here, take your body back! I'm done!

Just as the Thunder Queen raised her whip, preparing to deliver her next blow, the figure on the ground suddenly raised its head.

The golden pupils receded like the tide, returning to their original clear sky blue.

"Wait, wait! It's me! One of our own! Stop fighting!"

Kiana was terrified as the whip crackling with electricity was about to strike her face. She immediately raised her hands and begged for mercy.

The Thunder Queen paused in mid-air, looking down at Kiana on the ground with a hint of inquiry in her phoenix eyes flashing with purple lightning.

A few seconds later, she put away the whip and nodded.

“This kind of naivety is something Celine really can’t fake.”

"Kiana!"

Seeing this, Theresa could no longer hold back. She immediately broke free from Gu Ye's arm and ran to Kiana's side in a few quick steps, helping her up. "How are you? Are you alright? You were fine just now. How did you suddenly get taken over by Sirin?"

Kiana, supported by Theresa, stood up unsteadily.

She first glanced with lingering fear at the Thunder Queen, who had retracted her stand and transformed back into Mei, before her gaze drifted uncontrollably towards Gu Ye and Mei not far away.

Seeing the genuine worry on Mei's face, she felt a secret thrill for no reason.

Hmph, it seems I still hold a pretty high place in Mei's heart.

Kiana's mind raced.

It seems that Mei and Gu Ye don't want the headmistress and the others to know about their affair.

Since that's the case, I'll keep it a secret for her too.

Thinking of this, she cleared her throat, tried to appear nonchalant, and made up a lame excuse for Theresa: "Ah, well... it's nothing. It's just that Celine said she was too bored inside and wanted to come out for a walk and get some fresh air. I thought, since everyone's here, she can't cause any trouble, so... I lent her my body to play around for a while."

The reason was so lame that even Rin Tohsaka couldn't help but facepalm.

Surprisingly, Theresa believed it.

She stood with her hands on her hips, poked Kiana's forehead with her finger, and looked at her with exasperation: "You idiot! You can't just lend your body out to play around with! What if something happens?!"

"Because it's Kiana, she's certainly capable of doing something like that."

Himeko took a sip of her drink and added with a smile.

"That's it!"

Kiana, pleased with herself for getting away with it, immediately put her hands on her hips and changed the subject, saying, "But seriously, Sirin is such a disgrace to me! She couldn't even beat Mei's Stand! What a piece of trash!"

As soon as she finished speaking, a golden light flashed in her left eye.

A completely different, sarcastic voice came from her mouth: "If you're so good, then you do it! Who knew that woman's control over the Herrscher of Thunder's power was even better than mine! That's just not right!"

"Ha, isn't that because you're incapable?"

Kiana rolled her right eye and retorted in her original voice.

"What did you say?! Go ahead and try that whip if you dare!"

"I'm not as stupid as you to go looking for trouble with her!"

"Are you saying I'm stupid?!"

"Isn't that right, you idiot, Sirin!"

Kiana stood there, playing two roles, bickering wildly with two completely different voices and tones.

One moment it's Kiana's energetic voice, the next it's Sirin's haughty tone, and her facial expressions keep changing accordingly, leaving everyone around her stunned.

"Um... Kiana, is she alright?"

Kitagawa Kaimu whispered to Rin beside her, "It seems like... she has a split personality."

"Ugh, it's really ugly."

A disdainful voice interrupted Kiana's "self-dialogue".

Vishdel crossed her arms, a mocking smile playing on her lips, and looked the disheveled Kiana up and down.

"You can't even control your own body, and you got beaten up by your own companions, crying for your parents. You've completely disgraced the Kaslana family."

She said slowly, "If I were you, I'd crawl into a hole right now instead of standing here like a clown putting on a one-man show."

"What did you say?! You cockroach hair!"

Kiana and Sirin's voices rang out almost simultaneously, their two wills unusually united, facing the common enemy.

Anger flashed in Kiana's eyes.

"What? Not convinced?"

Vishdel took a step forward, his aura turning dangerous. "Want a fight? I'm itching for one. Let me see how much stronger you are than that crybaby."

Just as a new round of conflict was about to erupt, Himeko stepped forward in time.

She put one hand on Vishdel's shoulder and shoved a bottle of ice-cold beer into Kiana's hand with the other.

"Okay, okay, just say a few words."

Himeko chuckled and smoothed things over, "W, why are you arguing with a kid who just got beaten up? Kiana, calm down too, come on, have a drink to cool off."

She paused, glanced around at everyone, and raised her voice: "It's a rare holiday, let's not waste it arguing. You've had enough of your afternoon nap, how about we do something else? How about jet skis? I just saw they rent some over there!"

Before Himeko could finish speaking and before anyone could react to the jet ski suggestion, two swift black shadows tore through the azure sky and plummeted vertically from the heavens at incredible speed!

"Bang! Bang!"

Two muffled thuds echoed as two shallow craters were created on the beach, and flying sand hit everyone's calves. When the dust settled, two tall figures appeared before everyone.

The girl in the lead had dazzling light golden wavy hair tied with a black bow. She wore a white short sports jacket and black hot pants that allowed her to move around easily, revealing a toned and powerful waistline. Her blue eyes were sharp as an eagle's, and she was vigilantly scanning her surroundings.

It was none other than Durandal, the strongest S-rank Valkyrie of Destiny.

The woman behind her had short, grey-blonde hair, wore an elegant black backless dress, and had an impeccable smile on her face. The beauty mark at the corner of her right eye added a touch of charm to her.

Rita Losweather, the vice-captain of the Undying Blade.

"Where am I... what's going on?"

Durandal's gaze swept over the mess on the ground and the swimsuits on everyone's bodies, her brows furrowing slightly. "We detected a strong Honkai energy reaction and thought it was the Herrscher descending."

"Lady Durandal, Miss Rita."

Mei called out their names with some surprise.

"So it's Miss Mei and everyone."

Rita's smile remained unchanged as her gaze swept over everyone, finally settling on Gu Ye and the disheveled Kiana. A knowing glint flashed in her eyes. "Looks like we worried for nothing."

After Theresa's rapid, multi-pronged explanation, Durandal and Rita finally understood what had happened.

"Kiana!"

Upon hearing that it was her younger sister who had voluntarily released Sirin, Durandal's voice instantly became eight octaves stern. She strode up to Kiana, looking down at her condescendingly, "Do you know what you're doing! Do you think a Herrscher's consciousness can be released so easily? What do you take your safety for? A joke?"

"I……"

Kiana shrank back, feeling intimidated by her sister's powerful aura, and muttered pitifully, "Gu Ye was there... so I didn't think about it too much..."

The moment she finished speaking, her left eye turned gold, and Sirin's mocking voice burst out: "What's wrong with you? Why are you so afraid of this man? What's so great about him? Are you even a member of the Kaslana family? Are you even a Herrscher? You're a disgrace to me!"

"What do you know! Shut up!"

Kiana roared back in her original voice.

Durandal watched as her sister began to "split her mind" again, and felt a throbbing pain in her temples.

She raised her hand and helplessly rubbed her forehead.

"Mr. Gu Ye."

Durandal ignored Kiana and turned to Gu Ye with a serious expression. "Is there any way to completely solve Kiana's problem? I mean, a way to solve it once and for all?"

Gu Ye shook his head and calmly replied, "No."

"Kiana and Sirin are of the same lineage; they were born from the same wish. One represents Sirin's good intentions, and the other represents Sirin's evil intentions."

He paused, then added, "To put it bluntly, it's a special form of schizophrenia. So, don't even think about eliminating Sirin, because eliminating her would be equivalent to eliminating a part of Kiana."

Durandal's brow furrowed even more; she felt more troubled than ever before.

A symbiotic relationship... that's much more troublesome than a simple enemy relationship.

"But I don't understand, if they are the same person, why would Sirin be so extreme and single-mindedly want to destroy the world?"

"Because all she experienced was betrayal, pain, and hatred."

Gu Ye's gaze passed through Durandal, as if looking into the distant past. "Durandal, you are Kiana's older sister, and in a sense, you are also Sirin's older sister. Moreover, during the Second Honkai Impact, Sirin truly served as your 'younger sister'."

"Sister... younger sister?"

Upon hearing this, Rita's eyes lit up, and she smiled as she spoke, "Lady Durandal, this might be a breakthrough."

Yulandel instantly understood what Gu Ye and Rita meant.

She took a deep breath, turned around again, and faced Kiana, who was still bickering.

This time, her gaze was still stern, but it carried an added sense of responsibility.

"Kiana, Sirin, both of you shut up!"

Her voice wasn't loud, but it was full of authority.

Kiana originally thought that, given Sirin's proud personality, she would definitely fiercely resist Durandal's orders.

But to her surprise, when Durandal spoke in that authoritative tone, Sirin actually shut her mouth and just stared at her stubbornly with her golden eyes.

"very good."

Seeing that this method was effective, Durandal decided to press her advantage.

She took a step forward, her gaze sweeping over Kiana's blue and gold eyes in turn.

"Listen, whether it's Kiana or Sirin, you are both my sisters."

Her tone was firm and heavy, “We share the same blood. As the saying goes, an elder sister is like a mother. Now that Mom is gone, from today onwards, I am your mother!”

"Both of you need to behave yourselves! Sisters should live in harmony, not quarrel like this. What kind of behavior is this!"
