Dear readers, I made significant changes and changed the story plot lightly and writing and thankyou for reading this fanfic.

MC has harem.

1. Rias

2. Nurumi

3. Nagini

4. Kuroka

(some may be added later, but the list is not going to increase not much)

Issei is also another hero (I admire Issei as hero of HSDxD). But this story focused on our MC instead of Issei. So, I am not going to steal Issei's harem except Rias. Since, I can't bear to leave her out of MC's harem.
