If vector manipulation meant destroying Earth by smashing the core, halting its rotation, or dragging it out of orbit—
Then his Death Eyes needed only one light slash across the right thread...
And the Earth would die.
That was the stark difference between Nanashi and the Type-Moon's Mystic Eyes.
He didn't simply see death.
He understood it.
He was immersed in a world of decay, a place full of death—
And it didn't affect him in the slightest.
Knock, knock!
A sharp knock echoed at the door.
"Come in," Yukino called softly.
Nanashi blinked.
He closed his Death Eyes.
The warped, dying world around him faded.
Everything returned to normal.
The room looked intact again. As if nothing had ever been wrong.
The door opened—
And in stepped Kaguya Shinomiya and Chika Fujiwara.
Kaguya cast only a brief glance toward Yukino...
Then turned her attention fully to Nanashi.
"There will be a handover ceremony for the student council president this afternoon," Kaguya said, her voice calm and formal. "Nanashi-kun, please be prepared—we'll need to give a presentation."
She had come specifically to deliver this message in person.
Nanashi responded flatly, "I don't want to write a speech."
Kaguya smiled slightly, as if she had anticipated that response.
Without a word, she stepped forward and placed a neatly folded sheet of paper on the table in front of him.
"I already prepared one for you."
Nanashi raised an eyebrow. "You're incredibly prepared. Thanks."
On the surface, Kaguya remained composed.
But internally, she was celebrating.
Ai!!! You were right! Good thing I listened to you! Nanashi-kun must think I'm thoughtful now, right?!
Then Nanashi turned to Chika and waved casually with a smile.
"Haven't seen you in a while."
"!!!"
Chika, who had been trying hard to act invisible, visibly flinched.
She forced an awkward smile. "H-Hello... long time no see."
Nanashi grinned playfully and added, "Thanks again for your hospitality."
"Ahhh!!"
Suddenly, as if triggered by a vivid memory, Chika's cheeks flushed red.
She dropped into a crouch on the floor, burying her face in her hands.
"Waaah! Don't look at me!"
"…"
Kaguya stiffly turned her head toward Chika.
Her eyes were vacant and lifeless.
No attempt was made to hide the murderous glint in her gaze.
You Cancer of Earth! You despicable boob alien! Just when exactly did you get involved with Nanashi-kun?!
The brief, teasing exchange between Nanashi and Chika was enough to spark a cascade of mental images in Kaguya's mind.
He had only flirted lightly with her—
but now Chika dared to act like she had a history with him?
Pretending to be invisible? Dream on.
Back to business.
Nanashi glanced over the speech and found no issues.
"I understand," he said simply.
Kaguya nodded. "I look forward to working with you."
With elegant poise, she tucked a strand of hair behind her ear and offered a polite bow like a noble lady, then turned to leave.
As she passed Chika, her icy aura could've frozen the hallway.
"C-Cold!"
Chika shivered visibly, then scrambled to follow Kaguya, avoiding Nanashi's smirking gaze.
Whenever I see him, I can't stop remembering those scenes from the Doomsday Game...
Shame. Shame. Utter shame!
And now I have to work with him?! The horror!
After the two girls left, Yukino let out a soft sigh.
"That Kaguya Shinomiya… she's really into you. She prepared everything herself."
Her heart tightened.
She could feel it—Kaguya would definitely be one of them.
Why... can't it be me?
The thought came unbidden.
Subconsciously, she began inserting herself into the imagined scenarios between Nanashi and Kaguya.
No! Shameless! Absolutely not!
She shook the idea from her mind, catching herself before it spiraled further.
A quick glance at Nanashi showed him calmly reading the speech, oblivious to her inner turmoil.
She sighed in relief.
"Honestly… being this popular should be a crime," she muttered to herself with a hint of melancholy.
Knock knock!
Another knock at the door.
"Come in," he called.
The door burst open.
Standing there were Shizuka Hiratsuka, looking troubled as always, and the lively Marin Kitagawa.
"Nanashi-kun! Yukino-chan!" Marin greeted cheerfully.
Shizuka stepped forward with a sigh. "Kitagawa wants to join your club."
"Approved," Nanashi replied without hesitation.
"…"
Shizuka's mouth twitched.
So you two already know each other?!
Then why drag me here? You just made me into a third wheel!
Fine! I'm leaving!
And she actually left.
Nanashi looked at Marin, curious. "So, why do you want to join my club?"
She grinned. "Because I've got superpowers too, of course!"
Nanashi gave her a skeptical look. "Your superpower…"
He really wanted to ask: Is that even a real ability?
Before he could say more, Marin leaned in boldly, close enough to blow warm air into his ear.
"Don't you like my power, Nanashi-kun?" she whispered. "No more freebies if you don't."
Nanashi's expression turned serious immediately.
"No! I love your ability! Please, bless me more."
"Hehe~"
Marin narrowed her glistening eyes and smiled sweetly.
"…"
Yukino stared at them with suspicion.
What ability...?
She felt completely in the dark—like an outsider.
Afternoon.
The student council handover ceremony commenced.
Nanashi stepped up and delivered the speech exactly as written, following the formal procedure.
No one in the school seemed particularly shocked by his appointment as president.
Except for one person—
one whose gaze lingered long and thoughtfully.
In the crowd, Utaha Kasumigaoka's moist, intelligent eyes were fixed on him.
"Nanashi… Nanashi…Fumei…"
She murmured softly to herself.
"Is it a coincidence… or something more?"
She wanted to know the truth.
She needed to verify it.
Everything was going smoothly for the newly appointed student council president.
Nanashi had just taken office, and it was time to visit the Student Council.
Student Council Room.
The interior was far more luxurious than the Extraordinary Research Club.
Expensive desks and chairs.
Elegant display cabinets.
A long, plush sofa.
At the moment, only two people were present:
Vice President Kaguya Shinomiya and Secretary Chika Fujiwara.
Chika sat curled up on the sofa, hiding her face behind a book, clearly trying her best to avoid eye contact with Nanashi.
"Greetings, President."
Kaguya stood up gracefully and offered a respectful bow, pulling out a chair for him.
"No need to be so formal," Nanashi said, sitting down.
As soon as he did, Kaguya brought over a cup of tea.
It was hard to believe this was the same Kaguya Shinomiya known across the school as the cold and untouchable "Ice Princess."
This might just be a privilege exclusive to Nanashi.
He took a sip of the red tea and nodded approvingly. "Your tea-making skills are impressive, Shinomiya-san."
A faint smile of pride crept onto Kaguya's lips.
But then—
"It's on par with Yukino's," Nanashi added casually.
"…"
Her smile froze. A dark shadow flickered across her face, though her voice remained as composed and gentle as ever.
"You mean Yukinoshita-san?"
"Mm."
"Are you... familiar with her?"
"We're very close."
"…"
Kaguya's internal alarms were blaring.
Strong rival! Strong rival! Strong rival!
Her tea is as good as mine?
The cold, highborn flower of the mountains… Yukinoshita Yukino. So similar to me in temperament…
She must be eliminated!
Meanwhile, Nanashi had no idea what storm was brewing inside Kaguya's head.
He flipped through a few documents, frowning. As student council president, he couldn't just push all the work onto others.
"Shinomiya-san…"
Kaguya's expression twitched ever so slightly.
Yukino gets called by her first name…
And I'm still Shinomiya-san?
Still, she smiled. "Yes, President?"
"Is the student council currently missing an accountant?"
"Yes," she replied smoothly. "The previous one was let go recently, and we haven't found a replacement yet."
Nanashi thought for a moment. "Then why not ask Yukino to take the position? I'm sure she'd be a good fit."
"…"
Kaguya's eyes trembled slightly.
Yukino again?!
Chika suddenly perked up and put down her book, leaping to her feet.
"Yukino-chan's coming too?!"
Kaguya's brow twitched.
This Earth Cancer is also close to Yukinoshita?!
"You're close with Yukinoshita-san?" Kaguya asked flatly.
"Of course!" Chika replied, making a cheerful "peace" gesture. "Yukino-chan's one of my ride-or-die besties! Along with Marin-chan, and that other girl… Ma? Me? Mi?"
"…"
Why does it feel like I'm the only one not doing well in this group?
Is Yukinoshita going to take my place too?
No… I won't allow it!
"Since you don't have an objection, I'll ask her when I get the chance," Nanashi continued.
Then, he turned to Chika with a half-smile. "By the way, why haven't you told me anything about your situation since then?"
"Uhh…" Chika awkwardly scratched her cheek. "The student council's been really busy…"
She was clearly lying.
Nanashi chuckled softly. He knew she was just being shy.
"Add me to your contacts. Message me if anything comes up."
"O-okay."
Right in front of Kaguya, the two exchanged contact info.
Behind her back, Kaguya's hands clenched into fists.
Her brain buzzed with suppressed fury.
Hehehe… Fujiwara-san, you greedy Earth Cancer. Always taking everything for yourself. A parasite who'll devour this planet. You must be stopped!
"Ahh!!"
Chika, with her back to Kaguya, suddenly shivered.
She rubbed her arms. "What's going on? I keep getting the feeling like… something's watching me."
Later, while Kaguya stepped out to retrieve some documents, Nanashi took the opportunity to ask Chika something.
"What ability did you get from the Doomsday Game?"
Chika beamed mischievously.
"Ta-da!"
She spun in place, doing a dramatic 360.
"Hm? Your ears…"
Nanashi blinked.
Her ears had grown—long and pointed.
"Elven ears?" he guessed.
"Bingo! I got elf powers! I can transform into an elf and cast wind magic!"
Chika proudly spread her fingers, and glowing green patterns lit up the air between them.
A soft breeze formed in the room… and then strengthened into a gust.
Papers lifted off desks and danced wildly through the air.
"This is wind magic! Pretty cool, right?" she said, eyes sparkling as she awaited praise.
Nanashi gave a thumbs-up. "Elf Chika looks gorgeous, and that wind magic is super useful."
"Hehe~!"
She giggled gleefully.
"But you're about to be in trouble."
"Huh?"
Just then, the door slammed open.
Kaguya returned, holding a stack of materials in her arms.
Papers, blown by Chika's magic, flew into her face.
One cardboard box landed squarely on her head.
Nanashi casually stepped away from Chika and pointed at her.
Kaguya's face darkened with every syllable.
"FUJI—WARA—CHI—KA!"
Her voice echoed like the roar of a vengeful demon.
"Eeeek!!"
Chika's terrified scream rang out through the student council office.
The day passed quickly.
After dinner, Nanashi lay on the sofa with Eriri and Sayuri while Kanae sat nearby, nibbling on some fruit.
From the personal storage of the chat group, he retrieved a gleaming white crystal—the Dragon-Slayer Crystal of the Sky Dragon.
"Eri, this is for you."
Eriri blinked. "Is this... a gem?"
At first glance, it looked like a brilliant diamond, catching the light in a dazzling shimmer.
"It's not just a gem," Nanashi explained. "This is called a Dragon-Slayer Crystal. Once used, it grants dragon slayer magic."
"Eh? Magic?!" Eriri gasped, wide-eyed.
Sayuri and Kanae looked over as well, their curiosity piqued.
"Dragon Slayer magic," Nanashi continued, "is a form of magic that uses the power of dragons to slay dragons."
Considering everything they'd seen so far—supernatural events, otherworldly beings—it wasn't hard to believe. Dragons and magic weren't beyond reason anymore.
Still, the name carried a weight of power that made Sayuri frown with concern.
"This must be expensive... Nanashi, you should keep it for yourself."
"Yeah," Eriri added, puffing her cheeks. "As long as you're around to protect me, I'll be fine."
Nanashi gently rubbed her head, smiling softly. "The world is changing. I can't promise I'll always be there to protect you."
He glanced toward Kanae. "And besides, it's not that useful for me. You can ask Kanae."
"It's true," Kanae affirmed in her quiet but confident voice. "Nanashi is already incredibly strong."
"Well... in that case…" Eriri hesitated, then nodded with determination. "Alright. I'll become stronger too. I might not be able to protect you yet, but I'll help however I can. I'll protect Mom, too."
"Eriri…" Sayuri's heart warmed. Her daughter had truly grown.
"Try it," Nanashi said, placing the crystal into Eriri's hand. "Focus and feel it with your heart."
