"Okay, as you all know... We have discovered a new enemy that we are not familiar of which are the dark nights... Mori here send some of his members to investigate but only one returned alive, he reported that the leader of the organization used a stick and chanted a spell which is a 'avada kedavra' and we aren't sure if it's true, so we must be on high alert." The president explained and the members in the room nodded.

"And as of right now, we are taking in some of the UA students." Mori stated taking them all by surprised.

"But Mori-san, did they know that the Port Mafia and the agency joined forces?" Atsushi asked.

"Yes, Atsushi-kun, they already know, the principal even come here to inform us and to give them permission." Mori replied.

"Tanizaki, you will be the one that will pick up the students from UA, understood?" Fukuzawa said making Tanizaki nod. "Understood sir." He respond.

"So as of right now, we still don't hav-" Mori was interrupted by a bright light blinding the room.

When it cleared it made them shock to what they see in front of them because in front of them was the three missing detectives that they are looking for but their clothing was strange, they are wearing robes with a snake emblem on the side of their chest.

"Woah! 'samu-kun! Ranpo-kun! I'm not transparent anymore!" (Y/n) exclaimed in an English language as she examine her hands and arms.

"Mine too!" Ranpo stated as he look at his hands.

"Did we really made it?" Dazai asked as they turned around and found the shocked faces of their comrades.

"We really made it!" Exclaimed (Y/n) as she covered her mouth and tears spilled from her eyes.

"(Y/n)-san!" Kyouka was the first one to approach and jumped into (Y/n)'s arms. "Kyouka-chan!" (Y/n) exclaimed as she cried while hugging the girl.

"Your back! Your really back!" Kyouka stated, as (Y/n) wiped Kyouka's tears.

"We're back Kyouka." Smiled (Y/n) but then it turned into a frown when she turned back to the others.

"Now, what's this I heard about all of you being restless since we have been missing? Hmm?" Said (Y/n) making the two boys nodded.

"Yeah, we clearly see you all when you all are going in a meeting but you couldn't see us." Ranpo stated making some of them sweated.

"Oi! You three, I kinda noticed that you three look younger than before." Kunikida mentioned it making the three froze, they completely forgot about that. The others also noticed that they looked younger.

"Ahahaha! About that..." Dazai started nervously while scratching his cheek.

"You see..." (Y/n) also said in nervousness.

"We kind of turned into a 6 years old when we got transported into the other universe." Ranpo finished making the three of them sigh.

"Another universe?!" The members asked in surprised while the president and Mori look at them wide eyed.

"Yeah, after president gives us a mission, we encountered (Y/n)'s stepmother, and we aimed for the kill but she throw a dark energy at us. That's all we could remember and we woke up in an orphanage that took care of us for one and a half year." Dazai explained while (Y/n) and Ranpo nod.

"Then, how did you three get back?" Mori asked in curiosity.

"About that, Uncle Mori. We really aren't be here for long, when we finish our task here, we will be transported back there until we finally finished that we think is our mission from the universe that we are transported into." (Y/n) stated sheepishly.

"Oh! You two didn't forget right?! About what you said!" Dazai exclaimed making (Y/n) and Ranpo confused.

The others also listened. "About what?" Ranpo and (Y/n) asked at the same time.

"You two said that when we finally get back here! You two will be willing to go on a triple suicide with me!" Replied Dazai with a pink blush on his cheeks.

"You two what?!"

"Are you kidding me?!"

"Why did you agree?!"

"Oh my gosh!"

The reaction of the others are priceless.

"You still remembered that?!" The two exclaimed.

"Yes! Of course!" Dazai replied with a smile making the two groaned, they thought that Dazai already have forgotten about that but to their luck he didn't.
