Elevator Girl debuted at #13 on Oricon Weekly Digital Single Chart with 8,414 Downloads (in Japan).
It also debuted at #42 on Billboard Japan Hot 100 with 1069 points.
The difference in ranking is because Billboard also measures physical sales.
For comparison, Starlight was #41 with 1150 points in it’s first week, and Distortion was #6 with 2881 points.
For older singles, Karate was #24 with 1816 points, Megitsune was #16 (no points were given back then), and IDZ was #14.
Finally, it debuted at #34 on Oricon Weekly Combined Single Chart with 3594 points. This one measures digital and physical sales + streaming.
