Many of their issues never got a conclusion, hence why Fujimoto said that in the interview. Same with Denji, he'll die before ever looking for Power because, according to him, he's been looking for Power this entire time. I guess she simply wasn't where he expected her to be, inside school-girl's panties that is. So Denji dies after the grueling effort of looking for Power which we've been reading for 120 chapters so far. A conclusion doesn't mean a happy ending as you say.
