In another world called Spirit World where all mortals and heroes that have died go, a toddler sat behind a large wooden desk, drumming his small fingers anxiously on the desk top while knawing on his binky. He was Koenma Daioh, the prince and if necessary ruler of Spirit World. Although he did not look it, he was actually almost 5000 years old. The tension he felt was killing him. Just a few moments ago, he was informed that an ice maiden had been kidnapped earlier in the day.

Reaching for the intercom on his desk, he pressed a button and called into it, "Boton, I want you to send me the Spirit Detectives right away."

A bubbly voice responded, "Yes, Koenma sir! Be there in five minutes."

Soon, the two great and golden doors in front of him burst open. A girl with blue hair tied back in a ponytail and wearing a pink kimono came in. Behind her came four boys. The first that entered seemed to have the air of a leader. His dark hair was slicked back, and his chocolate brown eyes looked at Koenma with boredom. The second boy that walked with the first was at least half a foot taller with orange, Elvis-like hair and beetle black eyes. The two wore the same plain school uniform with the exception that the first wore it green, and the second wore it blue. A third boy walked in the office behind them. He also wore a uniform of magenta coloring, but this uniform had a different lining down his front. He had long, red hair and kind emerald eyes. The last to walk in was the shortest of the group. He had gravity-defying, black hair that made him taller than he appeared. The light gave his hair a shine at his forehead that was covered with a white cloth. He wore all black except for a white scarf around his neck. Like the first boy, his crimson red eyes showed boredom as he walked over to a corner and stood there. The rest of the boys situated themselves in front of the toddler with the blue haired girl at his side.

"What do you want now, binky-breath?" rudely asked the leader.

A vein appeared on the tiny ruler's head. "Yusuke, don't call me that!" he yelled.

The teen in green rolled his eyes while the boy in blue snickered beside him.

Koenma cleared his throat before growing serious. "I have grave news," he announced, his eyes flickering towards the shortest for a brief second. "Just hours ago, on her way back home to Koorime, Yukina was kidnapped."

"WHAAAT!! YUKINAA!?" screamed the boy in blue. The short one had a look of murder in his face while his eyes also showed a small trace of worry.

"Yes Kuwabara," confirmed Koenma. "Five B class demons are responsible for this."

"Koenma sir, why have they taken her?" asked the red head.

The short one growled. "Who cares why they have taken her. Where has she been taken??" he demanded, his eyes flashing dangerously.

The toddler nodded, slightly unnerved at the fury emanating from the short one. "Calm down Hiei," he commanded. Turning to the red head, he answered, "As for your question Kurama, they have taken her for the same reasons; for her tear jems." He took out a remote from a drawer and clicked a button. The boys turned their attention to a giant screen that rose from the floor behind them. A picture of an island surrounded by dark, murky waters and an inky black sky came into view. To the boys, the location looked oddly familiar. . .

"This island is what's left after the Dark Tournament," Koenma informed. "Yukina was taken here. You boys will retrieve her and dispose of the demons." He opened a portal, and the boys, one by one, silently stepped in.
