| Official Profile | HIKARU Introduction |
On the official Japanese profile, her name is written as ヒカル. Since her Korean name, English name, and Japanese name can each be used in titles, checking them with the group name Kep1er makes it easier to distinguish content. To avoid mistaking information about other individuals for her activities based solely on the name, use her official profile as a starting point. When familiarizing yourself with her face in group videos, watching one personal content video first can also be helpful.
Hikaru became a debut member of Kep1er through Girls Planet 999. Kep1er debuted on 2022-01-03 with FIRST IMPACT and WA DA DA. The background and member list from that time can be found in the debut showcase article.
If you liked the song in the first video you watched, listen to that album first and then move to other periods. There's no need to watch older material in chronological order. You can focus on a favorite performance or song and then explore activities before and after it. The current lineup and album entry guide are organized in the Kep1er Group Introduction. When watching past group videos, appreciating them with the lineup from that time makes it easier to understand why the number of members might differ.
In a bis interview on 2024-06-06, Hikaru mentioned CL as what inspired her to become an artist. She also expressed her desire to continuously grow without being complacent with her own performance. Hikaru Interview
Stories about artists who influenced her provide an entry point to understanding her music. However, there's no need to assume that all of Hikaru's stages are in the same style based solely on that fact. First, recall what stood out to you in the videos you watched. By separating the goals she mentioned in the interview from your personal impressions while watching her stages, you can appreciate them without the burden of trying to explain all of a person's expressions with a single short sentence.
On official Weverse, 私のバイブだよ！ Hikaru VLOG has been released. If you want to watch content centered around Hikaru, beyond group songs or performance videos, you can start here. Remembering the Japanese title as it is will make it easier to find again in the official list.
Vlogs are a format produced for a different purpose than stage videos. Instead of focusing on singing and dancing, follow the flow of the story. If translated subtitles are provided, check the language settings. If you've only encountered short edited clips elsewhere, I recommend watching the original video from beginning to end. You can fully enjoy it without assuming that the content shown is identical to her entire real life.
KILLA (Face the other me) is the title track of the 8th mini-album CRACK CODE, released on 2026-03-31. Album information can be found in the official discography, and an official dance practice video has also been released. This material allows you to follow Hikaru while observing the group's overall movements.
First, watch it with the music without pausing the screen. Second, try following one person, paying attention to the moments when they start and finish their movements. You don't need to know the name of every movement. If you find a part you like, simply recalling what sound it was associated with is enough. Repeated playback is a tool to not miss details, not a task to find the correct answer for appreciation.
If the dance caught your eye first, I suggest listening to only the audio once, then returning to the video. Remembering the sounds that stick in your ear and then watching the screen might reveal different aspects than before. Conversely, if you first learned about her through a song, observe how the members move together in the group practice video.
When the camera is close, facial expressions are clear; when it's far, the entire body and the positions of those around her are visible. Therefore, when comparing impressions from different videos, it's good to consider the filming style as well. There's no need to define the characteristics of all stages or rank members based on just one scene. After watching several songs, writing down the movements you repeatedly remember in your own words can help you understand your preferences more specifically.
If you want to read her own explanations about dance and rap, continue to Kim Dayeon's Introduction. If you want to watch personal vlogs alongside other members' content, you can find official materials in Huening Bahiyyih's Introduction. This is a way to explore different content formats within the same group.
In group videos that you've been watching with Hikaru as the focus, try shifting your gaze to other members once. Since the song is already familiar, you can concentrate on learning people's names and faces without having to memorize new music. As you accumulate the process of getting to know each member, you'll naturally be able to follow more during future group interviews or stages.
On official Weverse Media, you can distinguish between content featuring HIKARU or Hikaru by name and full group videos. For announcements about Japanese activities, also check the official Japanese website. Looking at the publication date and publisher, not just the title, helps differentiate original content from re-edited material.
Just because a new vlog is posted doesn't necessarily mean it was filmed on the same day. Performance videos can also have different release times than the actual event, so when curious about current schedules, refer to official announcements. The profile and links on this page are organized based on materials released as of the verification date below.
