Prologue

"KOENMA! KOENMA! KOENMA!" Botan yelled as she charged into his office. " We have a problem!"

"What is it now Botan? I am a little busy with the paperwork from the Wizarding world in England!" Koenma said as he sat at his desk arms crossed, bullying George.

Botan arrived at his door gasping for breath with a tall shadow behind her. "I just came from England. It's horrible! Look what's happened." Botan pulled the shadow into the light to reveal an old man dressed in robes, wearing half-moon spectacles. "This is Albus Dumbledore. He was the headmaster of Hogwarts of Witchcraft and Wizardry in England. He was working on finding Tom Riddle-baka, also known as Lord Voldemort. A double agent murdered poor Albus-san. Riddle has eluded the SDF for almost 17 years now. Albus-san and his prodigy Harry Potter-san have made more headway on the Riddle case in the last 6 years than Reiki has made since Riddle-baka eluded Hinageshi-kohai."

"We have found two of Riddle's accomplices in our search for him" Dumbledore spoke softly as he stared at the teenage version of the reaper and the prince of the spirit world.

"Yes, well who were those people you were able to apprehend so I can know how to punish them." said Koenma thinking that no punishment he could give to the two troublemakers could be as bad as the spankings he receives from his father, Enma-dono

"Their names are Crabbe and Goyle." stated Dumbledore.

"Thank you ." Koenma said.

" But Koenma, What are we going do about Riddle-baka?" asked Botan frantically.

"Call in Yusuke-kun! Tell him we have a special mission for him that, we need to interrupt his vacation in demon world for him to do it. Call in the others while you are at it, I think he will need all the help he can get."
