Description

The kanji spelling is "怪忌蝶(Kaikicho)" If modern idols are like "butterflies," then Phantom Siita is a heretical "moth" in the idol industry. It's scary and beautiful, making you want to reach out even though you know it's scary. It's filled with the hope that she will become an idol worthy of the word "idol." New for some, nostalgic for others. The real Japanese idols are here.

2 measurements spanning 14 days, net +1. Dots are measurements; the straight line between them is drawn to join them, not to claim we know the path taken in between — snapshots are recorded only when a count changes, so gaps mean “no change observed”, never “interpolated”. The vertical axis spans 32–33 and does not start at zero.
