Baby Beel, Or Beelzebub, the child of the Demon King, was Sent to the Earth to be raised by a Powerful, Heartless Villain who would raise him up to destroy humanity. That was sort of found in the Delinquent, Oga Tatsumi. With Hilda, the Maid and Mother, they had begun to raise him, preparing for his future.

But at the same time, Beings of other religions were annoyed at the fact Baby Beel was sent to the Earth. So They sent babies of their own to find suitable parents, and reign supreme as the strongest demon lord. At this point, it was no longer about destroying Humanity, even the Demon King, who was rarely serious, agreed to this. It became a show-off contest to determine who would be strongest enough to destroy the world....

TEAM HADES:

The Greek Gods were also fed up with The Demon King's boasts and decided to maintain their power, even if it meant destroying the Earth.

Their child is the one known as Baby Than. Short For Thanatos, name of the daemon that personified death.

1) Parent
2) Mother/Maid
3) Baby Than (Can be Shared by Parent and Mother/Maid)

TEAM ASURA-

The Asurans were Lower Gods and Deities of Asian Religion. fed up with the boasts they often recieved via letter, E-Mail, and Hell News TV, they decided to prepare the birth of the strongest Asura around.

In this case: Baby Aku. Which is short for 'Akuma' meaning Devil. The Child was given a stolen essence of the parent's soul to connect them better.

The Human they chose was a strong fighter, who could potentially have become an Asuran Death God himself.

Fun Fact: Baby Aku likes to "Messatsu" pronounced as "Meh-Sats!" and making Bruce Lee style 'ATA!' noises.

1) Parent (Reserved for me)
2) Mother/Maid
3) Baby Aku (Can be Shared by Parent and Mother/Maid)
