All Four Twins of the Duke’s Family Are Overpowered

Four twins are born into the Reinberg family!

But... all of the twins are extraordinary.

The eldest is the supreme master of Murim,

the second is the ruler of demons,

and the third is an angel descended from heaven.

They were intruders who once invaded Earth in a previous life,

and I, the youngest...

"Who were you?"

"Gandavia."

I was the defense force that protected Earth.
