Trackers and recaps for Meloco Kyoran’s 3D debut on June 27, 2025 (JST) report a peak around 125k, with some listings giving 125,400.
For context, late‑2024 rankings (before Saba and Flow Glow’s 2025 debuts) already showed Hololive (HoloX) members filling most of the top five behind Sakuna—not NIJISANJI EN.
