a sexy fox mama for the harem?. I hope so. It would be interesting to see how their relationship develops.
I sincerely hope the MC meets the demons and clears this karma with them before leaving for the next world. Maybe he should help out a little to pay for the Boosted Gear and settle that karmic debt too. He's already seen Issei's future importance so he should probably do it to strengthen him or all the problems Issei would solve will pile up, get worse and be left for the MC to deal with later.
