"Do you know? Actually I want to say something about our school's science project" Sanemi said.

"What's it?" Giyuu glanced at Sanemi.

"Seriously, there's nothing special about our school's science project" Sanemi rolled his eyes.

"What do you mean?" Giyuu was curious.

"JUST LOOK IN FRONT OF US! IT'S JUST A BROWN TEDDY BEAR TIED ON A 10L BOTTLE ROCKET YET YOU CALL IT A SPECIAL PROJECT!?" Sanemi complained. "EVEN MY MOTHER CAN DO BETTER THAN THIS ONE!"

"But having a teddy bear as a cosmonaut would be a trending article on news portals" Giyuu said.

"That's not the point" Sanemi sighed in frustration.

"Yummy! Such delicious ice creams!" Kyoujurou appeared next to them, carried a lot of ice cream cups.

"Hey, where did you get a lot of ice cream cups?" Sanemi asked.

"I saw an ice cream truck near the school's fountain" Kyoujurou answered. "Want some?"

"Okay" Sanemi took two ice cream cups from Kyoujurou before gave one of it to Giyuu.

"Can we launch the rocket now, sensei?" Murata asked as he was prepared to lit up the bottle rocket.

"Not yet, there's something I need to check first!" Obanai replied as he was about call someone. "Hello? Is the girl with pretty braids has already in there?"

Murata just gave his chemistry teacher a weird stare.

"Look, Haruhi! It's awesome, right? They're going to send a teddy bear to space!" Tamaki was excited as he clapped his hands.

(silent)

"Haruhi?"

When Tamaki turned his face to search for his wife, he saw Haruhi was chatting with Ritsu Kasanoda, the head of an infamous yakuza group. Ritsu's left arm was bandaged after he fought in a duel against Muzan's right hand man and secretary, Kokushibou.

"Thanks for coming, Ritsu-san! Where's your wife?" Haruhi asked her yakuza friend.

"I'm sorry that she couldn't come today, but Tetsuya is here to accompany me" Ritsu replied.

Tamaki's face was showing sad expression.

"Oh my sweet little Haruhi, why did you abandon me?" Tamaki pouted.

"Want ice cream?" Kyoujurou offered Tamaki his ice cream cups.

...

"The Galilean Moons are the four largest moons of Jupiter..."

The evil politician, Muzan Kibutsuji sipped a cup of cappuccino as he watched a documentary of Jupiter, the largest planet in Solar System.

Beep! Beep!

Muzan just received a call from a mysterious number. And for some reasons, his heart suddenly felt a bit of uneasiness. He put back the cup on the table before answered the call.

"Hello?"

"Well hello there, Kibutsuji! Today's weather is very nice, is it?"

Wait a minute. That voice, he knew that voice. It was Kyouya!

But Muzan had already blocked his phone number. Did Kyouya just changed his phone number or something?

"I thought I've already blocked your phone number" Muzan stated with a frown.

"I can still track your presence no matter what you do. And the same thing also i can say to your spies"

Muzan suddenly froze in shock.

"My...spies? Wait, wait, what in the name of my glory are you talking about!?"

"Ah, I'm just stumbled upon one of your spies in here, and i'm invited him for a nice picnic. I'm so surprised that he's very loyal to you, Kibutsuji"

"Aaaaaargh! Let me go, you bastard!"

Muzan's eyes widened as could heard Kaigaku's screams.

"I must say that I'm disappointed when someone sent their minions to sabotage my old school, especially a wicked person like you" Kyouya commented.

"Listen, you peanut! You better release my underling now or-"

"Yes, yes, I know it. You always repeated the same thing again and again, and it's pretty boresome to me"

"You messing with the wrong person, Ootori!" Muzan shouted.

"Excuse me, it was you who are messing with the wrong person. Ah! Perhaps I should warn the other schools about the presence of your spies, and maybe I can start with...Kimetsu Academy? Hmm...I wonder how will Ubuyashiki react if he finds out that two of his enemy's spies are infiltrating his school?"

"Don't you dare, don't you dare!"

"Sorry, got to go now. Have a nice day!"

Kyouya ended the call. Muzan's smartphone fell off on the floor from his hand.

...

"On nom nom nom!" Inosuke happily ate a large bowl of ice creams.

"Satisfied now?" Aoi stared at him a bit of frown on her face.

"Your teacher? Hmm... think i have seen him recently" an Ouran female student spoke to Tanjirou as he showed her the picture of Tengen via his smartphone. "He said he was looking for my school's art room and I told him to go to the third floor"

"WHAT!? WHY DID YOU TELL HIM!?" Zenitsu gripped the girl's shoulders in panic. "HE'S GOING TO BLOW YOUR SCHOOL'S ART ROOM!"

"HOW SHOULD I KNOW!? AND WHAT KIND OF AN ART TEACHER IS THAT!?"

"No time for arguing! We need to find Uzui-sensei immediately!" Tanjirou pulled Zenitsu away from the girl before dragging him upstairs. "Anyway thanks for the info!"

The girl only gave Tanjirou and his friends a weird stare.

As they finally reached the next floor, they spotted Tengen almost opened the door of art's room. Much to everyone's shock.

"UZUI-SENSEI, STOP!" Zenitsu yelled.

Tengen froze in shock. The Kamaboko group were here to stop his malicious intentions.

"DON'T YOU DARE TO BLOW UP OURAN'S ART ROOM, SENSEI!" Tanjirou warned.

"What are you doing here!? You guys should help Iguro-sensei outside there!"

"We have made a promise with Iguro-sensei to stop you from reaching Ouran's art room!" Tanjirou stated bravely.

"Kamado-kun, you must understand that explosion is an art! Explosion is the most beautiful art ever in the universe!" Tengen tried to defend his own intentions.

"Art or not, you aren't going to blow up anything in here!"

"Hey, what's going on here?"

Soon, Tengen was approached from behind by a pair of familiar orange-haired twins.

"Wait a minute! That's...that's..." Zenitsu pointed his index finger towards the twins.

"I know them, they're the guys who sells vegetables near my house" Inosuke interrupted.

"SHUT UP!" Zenitsu yelled at Inosuke. "They're Hikaru and Kaoru Hitachiin! The infamous fashion designers!"

"Fashion designers?" Tanjirou raised his eyebrows.

Tanjirou thought to himself, perhaps they're the ones Nezuko was talking about when she was reading a fashion magazine several days ago.
