I'm pretty sure Issei wouldn't be single, he still has Irina being his osananajimi, she will protect him by all cost, which sooner or later leads to the revealation of supernatural world, and Issei once again, even without Ddraig, will become a warrior to protect what precious to him, when he knows Irina is involved in this.

The story will start after Issei knows the deal, it will have more brain works for Issei and forces him to grow quicker to a tactician. Chance to get a harem still lower than in canon though.
