Phantom Siita (ファントムシータ / 怪忌蝶) is a five-member Japanese idol girl group produced by Ado.
They debuted on June 26, 2024, with their first digital single "Otomodachi".
They made their major debut with the digital single "Suki, Kirai" under Universal Music Japan on May 9, 2025.

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.
Group Name Meaning: “Phantom”, which are illusions and ghosts, and “Siita”, which is a combination of the scientific name of the Monarch butterfly, Parantica sita, and the scientific name of the swallowtail moth, Epicopeia hainesii.

Phantom Siita Official Fandom Name: Haine
Fandom Name Meaning: It comes from the scientific name for a mock swallowtail butterfly (Epicopeia hainesii)
