5th generation · TITAN CONTENT
エトハート / 앳하트
AtHeart take their name from joining the at sign to the word heart, and the concept is about building a world together with the people watching.
Last updated:
The pre-debut Good Girl leans hyperpop, Plot Twist turns dreamlike, and the 2026 double single moves toward R&B.
Start here for a new girl group aimed outward from the beginning rather than at the home market first.

AtHeart sits on hyperpop built from a multinational line-up, reaching out towards dreamlike sound. Arriving as the first K-pop girl group from TITAN CONTENT, the seven-piece takes its name from joining At, or the at sign, with Heart, carrying the idea of building a new world while staying connected to the hearts of fans.
The ways in are Good Girl, Plot Twist and Butterfly Doors. Good Girl gives the bright hyperpop of the pre-debut stretch, Plot Twist the fantastical pop feel of the formal debut, and Butterfly Doors the more dreamlike expression closer to R&B in 2026. The members come from Korea, Japan, the United States and the Philippines.
Aurora has been on hiatus for health reasons since July 2025, so it helps to keep the official line-up of seven separate from the activity carried mainly by six since Plot Twist. Good Girl into Plot Twist and on to Butterfly Doors spans the pre-debut work through to the present range.
Editors' take Good Girl / Plot Twist / Butterfly Doors — the span from multinational hyperpop to dreamlike R&B in three songs, from a seven-piece out of TITAN CONTENT.
No. 151 of 210 groups with recorded activity in Japan (top 72%)
The denominator is the 210 groups, out of 525 covered by KPOP DISCOVER, whose raw score reaches at least one point. The score adds 10 points per Japanese-market release, 3 per Japan-related track, 12 per member from Japan, and 8 per official Japanese account. Japanese-market releases carry the most weight because they are the most direct evidence of activity; related tracks add track-level detail; members from Japan stand for Japanese-language communication and continuity; official accounts stand for a permanent point of contact. The weights are an editorial judgement, not a statistical optimisation, and the ranking tracks release volume in Japan closely.
