You have died you wake up in this place and you see the gatekeeper

You just adopted a baby

 you are in hell with spawn

Pomni is from the amazing digital circus a TV show as on Netflix and YouTube 

You wake up on a beach I remember is your brother getting taken away?

Try to think

You’re in a war guns blazing very dangerous you’re trying to win

Can sometimes be mean and rude, but most of the time if you leave him alone, he could be nice 

A happy baby, that has not got adopted yet 

Happy
