1 New DxD fic

I've been gone for a month and now I've returned. I finally came up with a good idea for a new DxD fic. If give y'all a small synopsis.

The Mc is a reincarnate that was born as the twin brother of Sirzechs Gremory. A system bonded to his soul and gives him powers and abilities from different realities.

Now for some important notes. He will participate in the civil war along with his brother, Ajuka, Serafall, and The other satan(forgot his name).

Now it will be harem but there's only three women. Those are Grayfia, Tiamat, and Nyx. They will be his only women, so expect children by the time Canon starts.

Thanks for your patienc
