"There are seven other people in the world that look like you."

"People become ghosts because they have unfinished business."

BBB is a regular 14-year-old boy

The seven other people that looks like him are the seven elements

But they're all dead

All died at 14 years old

And they haunt the world, looking for revenge

Because only one person killed them all

That person's still alive

The elements don't originally know each other as they all came from different countries and died on different times

But they were connected by their same goal

In their travels, the came across BBB, who can see and talk to ghosts

The seven elementals asked BBB to help them get their revenge

BBB was skeptical at first, but he had a feeling that they were right so he agreed to help them

The seven ghosts fused with him, transferring their dormant powers to BBB

Their powers were the reason they were killed in the first place

And the person who killed them wanted to harness those powers for himself

It turned out that they didn't have to look for the murderer for a long time

Because the murderer was also looking for BBB

Apparently, he needed a vessel for the seven souls that he had killed, and what better if the vessel looks so much like them

Retak'ka was overjoyed when he found out that they had fused already

All he had to do now was to get BBB under his control

But they wouldn't have it

So BBB, with the help of the ghosts, defeated Retak'ka

BBB even severed the head for good measure

But since Retak'ka was now dead, there was no reason for the ghosts to remain anymore

They had started to fade

BBB was sad because he enjoyed their company

The seven didn't want to see him sad, especially after he had just helped them

So they left him their powers

"We left you our powers so that in some way, you will still feel our presence even in we completely disappear from this world."
