Finding our way back home (bsd x reader x Harry Potter the goblet of fire)

It's been weeks since the three came back to the Harry Potter Universe, and they already informed Dumbledore about it, so they will be back in Hogwarts again.

And they just find out that it's the tri-wizard arc when they come back, they noticed that it's different if they got transported back at there universe and back at the harry Potter universe again.

After a day or two, a letter arrived and it seems it come from Dumbledore.

"What does the letter say?"
(Y/n) asked as her and Ranpo lean to Dazai's shoulder to take a glimpse of the letter.

"It says that we have to go to the Hogwarts early than any other students because he had something to say."
Dazai's replied.

"Any of you had idea what this letter all about?"
He questioned, the two shrugged.

"Not a clue"
Ranpo responded and (Y/n) nod

"I guess we really needed to go huh?"
Dazai said.

"Yeah"
(Y/n) agreed

"It seems so"
Ranpo stated, and at the same time the three sighed.
