Right, the place where Damien ended up was the Sacred Abyss Universe.
It wasn't an accident either.
Damien arrived just as he wanted to, carrying with him everything he intended to take away from the Heavenly World.
'With a slightly volatile grenade…'
Damien looked at his left hand, where a yellow orb the size of a bath bomb calmly pulsated as if it wasn't made of Godly amounts of chaotic energy that could blow at any second.
'...and some sort of interdimemsional cosmic entity…'
Damien looked at his right hand, where he held that beasts contained in a barrier of Existence. It was trapped for now and wouldn't be able to do anything he didn't let it.
'...I think this is going to be a pretty fun roadtrip.'
Damien's disappearance. It was partially out of necessity, and partially because he figured out a great way to use his time.
