Classroom

The whole class was chatting to one another without a care in the world while they waited for their teacher to arrive.

"The bell rang, why isn't teacher here?" Shinwoo yawned.

"Dunno," Giotto replied while making paper shurikens out of complete boredom. Tsuna flicked him in the head when he threw one which landed in her hair.

"Stop that," she scolded and he obeyed instantly. The speakers turned on and an announcement was made.

"An announcement to Ye Ran High School students. It has been reported that a horrible incident has occured near our school. We advise you to go home right after school finishes from now on until there is further notice. Please, do not visit any remote areas and stay with your friends on the way home. Your home room teacher will fill you in with more details. That will be all." The speaker then cut off and most of the students became wary.

"What could have happened?" Shinwoo asked suspiciously. Giotto and Tsuna glanced at each other, both having a bad feeling in their gut. Pedro came into the classroom, looking very perturbed. 

"Okay guys, pay attention. As you guys have all heard, there was an incident near by. The police asked the school to make sure that the students go home right after to avoid any danger," Pedro informs them all.

"Sir, what happened?" Shinwoo asked the question on everyone's mind.

"Well, I heard it was a homicide," the student's began to feel terrified that a crazy murderer was on the loose.

"They have no information on the suspect yet. I was informed that it was not an ordinary murder case. I know it may be difficult, but try to home even if you have to skip afterschool classes." Pedro advises them.

"Yes, sir," they students replied, fully planning to listen to their teachers warnings.

"And Han Shinwoo, Woo Ikhan, Seo Yuna, Sawada Giotto, Sawada Tsuna and Cadis..." Pedro stopped and searched through his register when he couldn't remember his newest students name.

"Cadis Etrama di Raizel," he coughed awkwardly. "Ahem, six of you go to the Principal's office "

"What for?" Giotto asks him.

"I did not ask. Did you guys get in trouble somewhere?" Pedro specifically eyed Shinwoo and Giotto since they were the biggest troublemakers.

"No!" Both of them yell, utterly offended with their teachers look.

The Principal's Office

"Um... you asked for us?" Shinwoo said, peeking his head into the room.

"Please come in," Frankenstein tells them and Shinwoo, Ikhan and Yuna bowed in greeting before taking a seat.

"As you all know there has been a terrible incident..." Frankenstein trails off.

"A murder," Ikhan adds.

"Yes. The man yesterday could be one of the suspects. So the four of you have to be extra careful. That's why I asked to see you guys in my office," he then turned to his kids, "Tsuna, Giotto, you weren't with the others but you do hang out with them a lot so I'm asking you two to be careful as well," Tsuna and Giotto knew that meant that they had to watch their friends carefully.

"Yes, sir," everyone except Rai answers.

"Did anyone get hurt yesterday? Perhaps any injuries you haven't noticed yet..?" Frankenstein inquired but the the group confirm that they were all fine. "I'm really glad to hear that."

'I checked yesterday, but they had no scars. If they got any scars, they wouldn't be able to walk around like this,' Frankenstein theorised in his mind.

"Um... sir?" Ikhan asked, hesitantly, grabbing everyone's attention. "Something is bothering me. I think I should tell you..." Ikhan trails off.

"Ikhan, feel free to say anything," Frankenstein encourages.

"It's about the murder case," Ikhan admits, tensely. Everyone waits anxiously to see what he would say about the case.

"Was... was the weapon for the murder a trash can by any chance? If so Shinwoo is the killer," Ikhan finished and everyone looked at him incredulously though he took no notice. "Shinwoo attacked the man with the trash can... I saw it with my own two eyes..." Frankenstein says nothing.

"..."

"It must of hurt a lot."

"..."

"Sir, where's your trash can?" Shinwoo inquired, irked to no reason.

"S-Shinwoo?" Ikhan stuttered, startled.

"It's under my desk, Shinwoo," Frankenstein answers.

"Sir?" Ikhan cries.

After school

"Ouch, my neck still hurts," Ikhan complains while Shinwoo mutters that he is a crybaby.

"You deserve it Ikhan," Tsuna scolded, "honestly, accusingly Shinwoo of committing a murder, what are you, a high school detective?"

"It was kinda funny though," Giotto snickers even when being elbowed by his twin.

"You were lucky to get off with just a headlock," Shinwoo warns.

"Still you could've gone easy on me... hmm..." Ikhan claimed while rubbing his neck to alleviate the soreness.

"Thank you all for walking me home," Yuna appreciated them for being there for her.

"Not at all. We all live in the same neighbourhood anyways," Ikhan tells her.

"Right. The Principal lives nearby so Rai, Tsuna and Giotto can tag along," Shinwoo turns his head to Rai who nods in agreement. 

"You really think that man is the killer?" Ikhan's asks everyone. 

"No way," Shinwoo brushes it off, "they let us out early so I guess there may be something that is not quite right."

"It's a murder case. Our school is not like other high schools. And our Principal is not ordinary either," Ikhan jokes before gasping and turning to the twins, "no offence to you guys!" They told him it was fine and that they knew that their dad was weird.

"I'm sure dad decided to skip afternoon classes for us to go home safe asap," Giotto tells them.

"But still, a murder case is a big case," Tsuna warned.

"But if that man from yesterday was the killer... then the victim would have... been..." Yuna trailed off, knowing that if that was the case then she could have been the one killed. The rest of the group look at her in worry, they didn't want to think of such a thing.

"Hey, Yuna. That's impossible. You saw it yourself. That guy couldn't do a thing against Shinwoo," Ikhan comforted.

"Yeah, Yuna. I'll escort you everywhere until the perpetrator is caught. Don't worry," Shinwoo reassured, backing up Ikhan's point.

"That's a great idea," Tsuna commented.

"Yeah! There's no one who could beat our little Shinwoo in a fight!" Giotto exclaimed, grabbing Shinwoo's head in a lock and giving him a noogie.

"Hey, hey, hey! Let go!" Shinwoo yelled, trying to shove Giotto.

"Yep, besides Shinwoo was the one who kicked him. If he's got a grudge, it'll be against Shinwoo," Ikhan adds. 

"Hahaha! Yeah, I'm in more danger," Shinwoo laughs before paling once he realised what Ikhan said. "Eh? Really, Ikhan?"

"Makes sense, if I had been attacked with a trash can then I'd be pissed off at the guy who kicked it," Tsuna acknowledged. 

"At least it's better than Yuna being in trouble," Ikhan points out.

"True! Very True!" Shinwoo agreed, loudly. Yuna looked on for a second before giggling fondly at her friends antics.

"Thanks. You guys haven't changed a bit. I feel much better now."

"Ok, let's go to PC Bang!" Shinwoo announced out of nowhere.

"Shinwoo, how can this conversation end like that..?" Ikhan sighed, exasperated. 

"He wouldn't be Shinwoo if he didn't make those comments," Giotto snickers. 

"C'mon, it's still early. An hour should be fine, right?" Shinwoo mulled before pointing to the sky and declared, "alright! Let's go!"

"Ah, you drive me crazy Shinwoo," Ikhan complained but followed his best friend nonetheless. Tsuna, Giotto and Rai trailed behind a small distance.

"We can never catch a break around these guys, can we?" Giotto let out a huge breath of air.

"Yep, but it's worth it since they're our precious friends," Tsuna countered. The twins beamed happily to one another before looking to Rai who was watching the other three in content. The twins threw each other a mischievous look and quickly grabbing an arm of Rai and dragging him forward. Rai flinched slightly, he was never handled in such a way and didn't know how to react.

"Come on, Rai. I'll teach you how to play!" Giotto offered, excitedly. 

"Yeah, right! I'm a much better game than you!" Tsuna taunted, jokingly. 

Rai sighed and gently got his arm out of their iron-like grips and nodded, smiling fondly. This new life is quite the experience for him.

On top of a building

"Come on... there are no clues," M21 complained.

"This kind of delicate tracking isn't exactly our area of expertise," M24 reminded but M21 doesn't respond. "If I eat everyone near that building, we might get a clue. Should I?"

"No, that won't be necessary," M21 replies, "we'll probably get new orders from above if we hang around here a little longer."

"Hm?" M21 looked to pavement and found something very interesting. "I think we found something to keep us entertained till then."

"What?" M24 questions before following his partners gaze. "That's... " M24 recognised the uniform.

"Keke... do you recognise the outfit?" M21 asked, rhetorically. "It's the same as those kids were wearing. Kekekeke. The idiot lurking in the sewers to avoid sunlight will serve to entertain us..." M21 cackled. 

Sewers

In the sewer, laid a very sickly man who breathed heavily as he curled into himself.

"Light... p-pain..." the creature growled in agony. He looks back at his encounter with Shinwoo and swears to kill him.

"Kill..."
