You don't have to reach the rooftop. You get four Shikis from completing the missions: 83 (complete 90 missions), 66 (Clear Room No. 1 on each floor), 53 (Defeat 40 Evil Servants) and 49 (Defeat 20 Rapunzel; I recommend the parking lot for this one since it guarantees you one for certain). Put those together with the limited one that becomes permanent after Room 504 and you should be able to max her NP. Hope this helps
