This shit been rushed since he skipped floors for his sister so this kinda pacing and ending was to be expected tbh. Pretty sad this didn't get a chance to blossom, clearly there were a lot of dropped plotlines, the stitched-up girl, Ran's master, that girl's dad, and the other demons. I really don't get why this didn't get a fair chance I mean it might be generic but I really don't think it was any worse or unoriginal than others that follow this kinda climb a "tower" obtain "skills" and reach the top manhwa. Feels like a lot worse and lower-quality works get way longer runs and fairer shots real shame.
