~Two years later~

Dazai's POV

It's been five years since we arrived in this universe, and we finally moved on from Gran Gran's death.

In the pass two years, we have been training our powers and studying about magic to improve.

And to those pass two years also, I finally convinced Ranpo and (Y/n) to finally join me on a suicide, though I know that they didn't do it on purpose but I still got their words!

'Oh, I can't wait to see the agency members faces when I drop the bomb to them.' I thought while rubbing my hands together with a mischievous grin.

(To those who don't know what Dazai meant is, He will reveal/tell them. That's what he means. It's not a real bomb that he referred.)

Third POV

"'samu-kun! Would you stop that?" (Y/n) scolded Dazai in their original language because it's now just the three of them.

"Yeah, Osamu, stop it, it's creeping us out." Ranpo stated as he lay down on (Y/n)'s lap while (Y/n) brushed her hair.

The three of them now really got closer, and (Y/n) also got used to the two's clinging personality, though she is still oblivious about the two's feelings for her.

They also got used to the people calling them the Tokubetsu siblings/triplets. They even got their own detective license, though they took a while to prove it to them that they are worthy enough to be a detective.

As the three was about to eat a cookie but suddenly, there is a knock on their window.

Dazai stood up and look at who knocked and it turns out it was an owl and it was caring a letter too, so Dazai grabbed the letter and give some seeds to the owl.

He then closed the window when the owl had left and returned to where (Y/n) and Ranpo is.

"It's another letter again, but this time it was an owl." Dazai stated as he showed the letter to them. "Opened it!" Said (Y/n), as she and Ranpo mover closer to look at the letter.
"It's from Hogwarts." Ranpo pointed out.

"Should we attend this school?" Dazai asked them, as the three of them started to think. "We should, the Hogwarts always had a lot of adventures." (Y/n) daydreamed, Ranpo and Dazai grinned. "We're in!" They said.

"It's time for another new adventure!" The three of them exclaimed and laughed after, they then continued to read the letter, when they finished reading, another letter fell down, so Ranpo picked it up and read it.

"Dear (Y/n), Osamu, and Ranpo Tokubetsu

I'm needing your help to protect Hogwarts and the students including Harry Potter, in exchange to it, I will be giving you a badge of the house that you will be put in to.

But the badge is not ordinary, I created it just for you three only, you can come back temporarily to your universe if they will need your help.

I will explain the details if you accept this mission.

From the headmaster Albus Dumbledore

We look at each other. "S-should we?" (Y/n) asked them.

"This is it, this is our chances, even though we can just temporarily come back there if they will need us." Dazai stated, as the three of them look at the letter with hope. "We will accept the mission." The three of them said at the same time.

"It even doesn't matter if  it can really take us back even if it's only temporary, so I don't why not." Ranpo said as the two nodded and look at the things that they will need.

Uniform

"So we have to go to Diagon Alley, huh?" Ranpo sighed.

"It seems so." (Y/n) nodded "come on you two, let's get dressed." She stated and drag Dazai and Ranpo who whined. "And 'samu-kun don't do any suicide attempt there." (Y/n) said reminding him, as he pouted.

"Now, come on!" (Y/n) said as they got in the fireplace one by one with a flu powder while saying 'Diagon Alley!' and they disappeared in a green fire.

~time skip~

After they finally got all their stuff, and their familiars. Dazai got a sandy owl and named it Diana in honor of their dead adopted mother. While Ranpo got a black cat and named it Ran, and (Y/n) got a white with black stripes cat and named it Shi, because it reminded her of Atsushi, she just moved out the Atsu and remained the Shi.

When they got back to the mansion, they immediately went to bed after they eat.
