DXD: Phenex System

I died but was then reincarnated as Riser Phenex with a System! Pretty cliché right? Well sorta, since I don't have to worry about the timeline I'm going to live my life as I want! What to expect: -Riser SI -Canon Divergent -Harem (Currently I've got Rias, Akeno, Sona, Serafall, Kuroka and two surprise girls.) -OP MC (Not immediately, but he will be OP) This is my first fanfic so I'd appreciate constructive criticism. Also let me know who else you want in the harem!
