once around 1867-1999 the ''seven fragment of the key'' fall from heaven

diabolu (temporal name) decided to visit the world in match of find them

not caring that he had to kill everyone for that

once that, he thought he already won, now would try to travel between universe and have infinite power

his dream was far of being real yet.

backstabbed at the moment of the of the truth and false pretender take the throne

left to die and falling from grace

Beelzebub, once more awaits
