So, let’s dig into who’s who, how old they are, and what they each bring to the table.

Meet LE SSERAFIM

LE SSERAFIM is a five-member girl group under Source Music, part of HYBE—the same company behind BTS and NewJeans. They stepped onto the scene on May 2, 2022, with their first EP, “Fearless.” Right from the start, their message was clear: bold, unapologetic, and ready to shake up the idol world. Even the name “LE SSERAFIM” is an anagram for “I’M FEARLESS,” which really sums up how they see themselves—confident and out to break the mold.

The members come from all over—Japan, Korea, and the Korean-American community—which helps them connect with fans worldwide. HYBE clearly had global reach in mind when putting this team together. The age differences give the group extra depth, too. The older members bring steadiness and a sense of direction, while the younger ones keep things lively and bring in new ideas.

Sakura – The Oldest

Miyawaki Sakura, born March 19, 1998, is 27 in 2025 and the group’s oldest member. She grew up in Kagoshima, Japan, and she’s no rookie—she’s been in the idol game for over ten years. Before LE SSERAFIM, she was already famous in Japan with HKT48 and AKB48.

Sakura’s big international break came with “Produce 48,” a Korean survival show. She made it into IZ*ONE and built a global fanbase. After IZ*ONE disbanded in 2021, Sakura paused to figure out her next move. Joining LE SSERAFIM was her chance to start fresh—this time, with even more experience under her belt.

Even though she’s the oldest, Sakura doesn’t act distant or strict. She’s fun, open, and keeps the group’s mood up. Her calm attitude and experience make her a natural support for the younger members, especially when things get overwhelming.

Kim Chaewon – The Leader

Kim Chaewon, born August 1, 2000, is 24 in 2025. She’s from South Korea and leads the group. Like Sakura, she was also in IZ*ONE before joining LE SSERAFIM. Fans already respected her for her strong vocals and solid work ethic.

Nobody was surprised when Chaewon became the leader—she’s gentle but knows when to step up, always listening and making sure everyone’s included. She balances her own goals with making sure the group sticks together.

Chaewon’s style is all over the map—in a good way. She can switch from soft and angelic to fierce and powerful, depending on the concept. At 24, she’s right in that sweet spot between the youngest and oldest members, which helps her keep the group grounded and balanced.

Huh Yunjin – The Korean-American Vocalist  

Huh Yunjin was born on October 8, 2001, so she’s 23 in 2025. She’s got this interesting background—she’s Korean-American and grew up in the US, mostly in New York. Because she’s fluent in both English and Korean, she easily connects with fans from all over. You can really see her bridging the gap between Korean and Western audiences.

People first noticed Yunjin during Produce 48. She didn’t end up in IZ*ONE, but her talent stood out anyway. She kept training, worked hard, and eventually came back to debut with LE SSERAFIM—stronger than ever.

What really makes Yunjin special is her musicality. She’s not just a talented vocalist with a rich, memorable voice; she also writes and composes her own music. Tracks like “I ≠ DOLL” and “Blessing in Disguise,” both released on LE SSERAFIM’s platform, show off her depth as an artist. At 23, she brings thoughtful lyrics, a global outlook, and a powerful voice to the group.

Kazuha – The Ballet Dancer Turned Idol  

Kazuha, whose full name is Nakamura Kazuha, was born on August 9, 2003, which makes her 21 in 2025. She’s from Kochi, Japan, and before K-pop, she was deep into ballet—training in the Netherlands and studying at top places like the Bolshoi Academy and the Dutch National Ballet Academy. She even competed as a professional dancer.

Her switch from ballet to K-pop was a surprise, but honestly, it’s become one of the coolest parts of LE SSERAFIM’s story. Kazuha brings this dreamy, graceful vibe to their performances; you can spot her ballet background in her movements on stage. Her long lines, smooth control, and calm expression make her stand out every time.

Even though she’s still pretty new to idol life, Kazuha has picked things up fast. Fans now see her as a symbol of elegance and discipline in the group. At 21, she mixes youthful drive with artistic experience, and that really shapes LE SSERAFIM’s identity.

Hong Eunchae – The Youngest Member (Maknae)  

Hong Eunchae is LE SSERAFIM’s maknae—the youngest—born on November 10, 2006, so she’s 18 in 2025. Her role? She brings this bright, energetic spark to the team. She grew up in South Korea, trained under Source Music, and debuted with the group when she was just 15.

Even though she’s young, Eunchae has grown so much in a short time. She adapted quickly, both on stage and with fans, showing a maturity you wouldn’t expect from someone her age. Her bubbly personality and quick humor make her a hit on variety shows and live streams.

She’s also a strong dancer. While she hasn’t trained as long as some of the others, her natural sense of rhythm and stage presence just keeps getting better. The older members dote on her, but Eunchae’s sharp wit and confidence make sure the group always feels lively.
