Top 5 Jimin Breakdown
| Rank | Idol | Group | Brand Index | Change vs August |
|---|---|---|---|---|
| 1 | Jimin | BTS | 3,905,514 | Holds #1 |
| 2 | G-Dragon | BIGBANG | 3,517,368 | +56.04% |

Jimin Stays Untouchable At #1
For yet another month, Jimin holds firm at the top with a brand reputation index of 3,905,514. His keyword analysis lit up with terms like “ARMY,” “Who,” and “Like Crazy,” alongside associated words like “beautiful,” “prove,” and “record.” Perhaps most impressive: his positivity-negativity analysis clocked in at a striking 93.82% positive reactions — a sign of just how strong his fanbase engagement remains.
G-Dragon’s Massive Comeback
The biggest headline this month belongs to BIGBANG’s G-Dragon, who rocketed to second place with a 56.04% increase in his brand index since August. That kind of jump usually signals a major public moment — a comeback, collaboration, or big media push — and it’s enough to put him firmly ahead of younger, more consistently trending idols.
San, Jungkook, And Jin Hold Steady
ATEEZ’s San maintained his third-place ranking, proof that his fanbase engagement remains rock solid month over month. BTS’s Jungkook edged up slightly to fourth with a modest 1.51% rise, while labelmate Jin rounded out the top five with a small 0.74% increase — both signs of steady, reliable brand strength rather than viral spikes.
The Rest Of The Top 30
Rounding out the list are BTS’s V, ATEEZ’s Wooyoung, TVXQ’s Yunho, Wanna One’s Kim Jae Hwan, and CORTIS’s Keonho in the top ten. Further down, familiar names like EXO’s Baekhyun, RIIZE’s Wonbin, BTS’s RM, SHINee’s Minho, and Super Junior’s Kim Heechul all made the cut — a reminder that legacy idols and rookies alike continue to hold strong public relevance.
Notably, rising group CORTIS placed three members (Keonho, Juhoon, and Seonghyeon) in the top 30, signaling their growing traction this year.
