Third POV

Two weeks had passed since (Y/n), Dazai, and Ranpo started attending the school for witches and wizards. For them, the classes are boring because they already know all of the classes the Professors lessoned for all of them students.

Ever since they stepped into Hogwarts, they have been the talk to all of the students because of their looks and talent.

The Slytherin talk with pride to the Tokubetsu siblings because of their skills in flying, spells and academics, the defense against the dark arts and potions. Though Dazai tried to make a poison without anyone noticing but everytime he tried, it's either (Y/n) would stop him or Ranpo but mostly it's (Y/n) because Ranpo was also busy gaining (Y/n)'s attention or helping (Y/n) with the potion.

There still one time that they went to the roof to get some fresh air, Dazai stood in the edge of the roof to jump off and it took them for a while to get him down if it weren't for Ranpo's hammer to knock him out.

/////////////////

The three, Ranpo, (Y/n), and Dazai made their way to the Slytherin table. Today is Halloween and most of the students look at them with admiration but they ignored them and sat down on their seats.

As the food was served, the three, (Y/n), Ranpo, and Dazai immediately lit up in delight. (Y/n) grabbed the (f/d), Ranpo grabbed some...er.... A lot of chocolate chip cookies and candies, and Dazai grabbed some candies and some cupcakes.

They happily eat their food, they were interrupted by the Great Hall or Dinning Hall's room doors slammed open.

"TROLLS! TROLLS IN THE DUNGEON!" Quirrell screamed as he came running in. All of the people in the hall were silent.

"I thought you should know." He then 'fainted.' Ranpo, Dazai, and (Y/n) shook their head in disappointment and sighed.

The three of them talked calmly like nothing was going on as the students panicked.

"His gonna be a good actor, but he completely forget that the teachers are supposed to be tough to protect their students." Dazai stated loud enough to the three of them to heard it. "How many trolls got in by the way?" Dazai questioned.

"Three, there's a total of three trolls." Ranpo and (Y/n) replied in unison, making Dazai shiver. "Stop that! You two are creeping me out!" Dazai said as (Y/n) stuck out her tongue and giggled.

"SILENCE!"

The three of them heard Dumbledore's voice.

"Now, prefects lead the students to the dormitory, teachers will come with me." Dumbledore announced.

(Y/n) grabbed Dazai and Ranpo, she then teleported away without being seen.

"Okay, since there are three trolls we eliminate each of them." Ranpo explained but (Y/n) disagree. "No! We are not going to eliminate them in front of the students! It will surely give them nightmares for who knows how long!" (Y/n) exclaimed.

"She has a point." Dazai said. "So what do we do now if we are not going to eliminate them?" Ranpo asked (Y/n).

"With this!" (Y/n) used her magic to make three empty glass cards appear. "I made it with an ordinary mirror and put some magic into it to make it less fragile and not easily to break, you just have to throw it in front of the weakened enemy and the enemy will automatically be trapped inside this magical prison glass cards!" (Y/n) explained and handed them each of the cards, while Dazai and Ranpo examined it.

"This is gonna be useful, how many did you make?" Ranpo asked her, as she fiddled with her fingers. "I still only made three." She replied.

"Come on! We gotta defeat those trolls!" Dazai and Ranpo was about to leave if it weren't for (Y/n) holding the back of their collar.

"You two should be responsible sometimes! You can't just go there without hiding your identities! Specially if those golden trio are around! They'll suspect us that we are enemies!" Scolded (Y/n) as the two boys whined, (Y/n) then let go of their collars and throw a cloak to each of them with a animal mask.

"Why does mine is a dog?" Dazai scowled by just looking at the mask, as Ranpo put his cloak and cat mask on.

"Don't be like that 'samu-kun, you don't want me to be heart broken do you? Because I'm the one who made this masks." (Y/n) said as she look at Dazai with a puppy dog eyes with tears at the corner of her eyes making Dazai to panic.

"A-ah! (N/n)! Don't... Don't cry! I love the mask! See! I'll put it on!" Dazai put on the cloak and the mask, as he continued to panic, making (Y/n) giggled and smiled.

"I was just joking, I didn't know it'll work like a charm." She said making Ranpo snickered at Dazai.

"Huh?!?!" He said in shock.

"Anyway, I'll take the one in the corridor, Ranpo-kun take the Dungeon and 'samu-kun take the Slytherin's house." (Y/n) command and put on her own cloak and fox mask, as the two boys nodded and they took each different paths to their destinations.

Ranpo's POV

I run to the dungeon and found a troll, it was quite big but nothing I could handle with the use of my deduction, as I came to a stop, my shoes squeaked making the troll notice me, and he swing down his bat at me but being in a detective agency member and trained together with Dazai and (Y/n) for a long time, I dodge it skillfully.

"Is that all you got?" I said and grabbed my small hammer that is hidden in my pocket and make it big, I then swing it down at the troll's head making his eyes roll back and drop to the floor unconscious, I make my hammer back to its small size and put it back in my pocket.

I throw the magical glass card that (Y/n) give to me in front of the troll and it immediately trapped the troll in it as I picked it up after.

I turned around and saw the professors surprise look, as they pointed their wands at me.

"You should go next to the other two trolls." I said and snapped my fingers causing me to teleport at the back of my fellow Slytherin, I then make my outfit (The cloak and the mask) disappear and watched the show.

////////////////

Dazai's POV

I followed my fellow Slytherin student and caught a vibration on the ground coming from behind me, I turned and jumped to the side just in time for the troll to swing down it's bat, I look at the damage that it caused on the floor and cringed.

'That'll definitely a painful death, I don't want to die like that so...' I thought jumped back to avoid another attack, the troll came forward while I stepped backward, I then stepped on the wall instead of the floor, meaning it already a dead end, I sighed.

'Guess I don't have a choice.' I thought and raised my arm, as the bow appeared and I stretched the bow string making an arrow appeared, I then released it and it pierced into the troll causing it to faint because it's a also magical creature, the arrow nullify it's magical energy instead of its life force making it unconscious and drop to the floor.

The students who are watching was in a state of shock while Ranpo at the back was grinning and give me a thumbs up making me grin underneath my mask.

I gently put the magical glass card in front of the troll and stepped away as the troll vanished and got trapped in the card.

As I picked up the card, the professors came running in but they are too late, I already captured the troll.

"Too bad you didn't made it in time to watch the show, what a shame." I said while grinning underneath the mask. "You should hurry to the corridor if you don't want to miss the show." I stated and snapped my fingers making me teleported away from the teachers and appeared beside Ranpo who nodded at me when we saw the teachers run again, Ranpo put on his mask and cloak again and we snapped our fingers teleporting to where (Y/n) is.

//////////////

(Y/n)'s POV

I arrived in the girls bathroom just in time before the two boys, could do something risky.

I appeared in front of Hermione and grabbed her, I immediately teleported beside the two boys causing them to scream in surprise, which also make the troll notice us.

But before the troll could do anything, I bend the water to surround the troll's body and froze it, I then punched it very hard causing it to be unconscious and to my opinion, it's just very easy, and why does the three of them got a hard time defeating it in the plot, but then I remembered that they are still a studyand an amateur.

"Um... Who are you? I want to thank you by the way for saving us from the troll." Hermione stated as I turned around to look at her, I smiled underneath my mask, happy that someone thanked me for my good did.

"Your welcome, but who am I is not important."  I said as I took the magical glass card out of my sleeve and throw it in front of the troll causing it to be trapped inside.

I grabbed it and look back at the trio who was awe struck from seeing it. "Wicked." I heard Ron said and I bit my lip to prevent me from giggling.

"Oh goodness me! Who are this people?!" I turned around and saw that McGonagall was the one who said it and beside her was the other professors.

Ranpo and Dazai appeared of my side and we handed the cards to Dumbledore who didn't hesitate to receive it. "Thank you, whoever you three are." Dumbledore thanked and we three nodded our head and we snapped our fingers causing us to teleport to out rooms thst is still didn't have any of our fellow Slytherin students and went to slept immediately.
