HIGHSCHOOL DXD X TALES OF BERSERIA CROSSOVER

Unknown to Issei Hyoudou, he is the grandson of a powerful being that came from another world. When Raynare kills Issei on their date, a malicious red energy warps Issei back to his home and heals him. Now involved in the supernatural world, Issei is forced to face powerful beings. But he's not alone for his grandmother has decided to step in and fight. Now the one thing that the supernatural world will know, is to never mess with the family of Velvet Crowe.

NB 1:

Less perverted Issei

Non-devil Issei (I'm sure Velvet will be very unhappy knowing her grandson is a slave to someone.)

OPTIONAL: You can decide whether Velvet will have allies in which of the three factions. (Youkai Included)

OPTIONAL: You can choose how Issei uses his power of malevolence and how it appears physically. (Like how the malevolence manifests as Velvet's arm.)

OPTIONAL: Issei can have his Boosted Gear.

You can decide whether Issei's mother or father will be Velvet's child.

Issei's grandfather must be human

You can decide the fate of his grandfather and whether he was aware of Velvet's power or not.

How they fell in love is of your choice.

Since there is no malevolence in the DXDverse, Velvet can feed on the malicious nature of senjutsu and the energy of the demons of the DXDverse.

NB 2: Just to clarify. While trapped in the seal, the soul of Laphicet Crowe awaken within Innominat. He decides that his sister deserves a second chance. So by using a powerful space-time arte, Laphicet pushes Velvet out of the seal, but the arte 'malfunctions' and warps Velvet to another world where she wanders around for a few hundred years before meeting Issei's grandfather and giving birth to his mother/father. Issei's mother/father will not have access to the power of malevolence, but he/she is aware of the power that Velvet wields. Also, malaks are known to possess a wide variety of artes, so it is plausible for some to have a few space time artes capable of making a temporary tear in dimensions. An example of this is the arte used to seal Velvet and Innominat away in a sort of pocket dimension.
