When KATSEYE first burst onto the scene via The Debut: Dream Academy, everyone was obsessed with the talent, the drama, and that slick Netflix documentary. But now that they’re officially moving as a unit, fans are getting into the nitty-gritty of group dynamics. One question keeps popping up in the comments: whos the oldest in katseye?
If you just look at their height or how they carry themselves on stage, you might guess wrong. Group leader Sophia has that "big sister" energy that usually belongs to the eldest, while Manon has a sophisticated, model-esque aura that feels mature. But in the world of global pop and K-pop-inspired groups, birth dates are everything.
The Answer Might Surprise You
So, let's get straight to it. Manon Bannerman is the oldest member of KATSEYE.
Born on June 26, 2002, in Zurich, Switzerland, Manon actually beats out the group's leader, Sophia, by about six months. It’s a classic "fake maknae" situation—not that Manon acts like a baby, but she definitely isn't the one constantly corralling the girls during interviews. That job falls to Sophia Elizabeth Guevara Laforteza, who was born on December 31, 2002.
Honestly, the gap is tiny. We’re talking about two "02-liners" (as fans call them) who are both 23 years old as of early 2026. Because their birthdays are at opposite ends of the year, Manon has been the unofficial "unnie" (older sister) since the jump, even if she doesn't use the title in a traditional K-pop sense.
Why Manon’s Age Actually Matters
In many girl groups, the oldest member is automatically the leader. It’s a cultural thing, especially in South Korea. But KATSEYE is a global group managed by HYBE and Geffen, so they did things a bit differently.
Manon being the oldest brings a certain groundedness to the group. She didn’t come from a traditional "trainee" background like some of the other girls. Before the show, she was already living a whole life as a model and influencer. That extra bit of life experience probably helped her navigate the intense pressure of the survival show, where she was famously the "underdog" who had to catch up on dance skills in record time.
It's kinda wild to think about. While the younger members like Yoonchae were basically kids when they started training, Manon already had a sense of her own personal brand.
Breaking Down the Full Age Hierarchy
To really understand the group's "vibe," you have to see where everyone else fits. It's not just about whos the oldest in katseye, it's about the "line" they create.
- Manon (June 26, 2002): The Swiss-Ghanaian visual and the undisputed "big sister."
- Sophia (December 31, 2002): The Filipino leader who is only six months younger but definitely the "mom" of the group.
- Daniela (July 1, 2004): Our main dancer from the US. She’s firmly in the middle.
- Lara (November 3, 2005): The powerhouse vocalist. She turned 20 recently and is part of the "younger half."
- Megan (February 10, 2006): Just a few months younger than Lara, Megan keeps the energy high.
- Yoonchae (December 6, 2007): The "maknae" or youngest. She’s only 18, making her five years younger than Manon.
That five-year gap between Manon and Yoonchae is actually pretty significant in the music industry. It means they grew up with slightly different cultural touchstones. While Manon might remember a world before TikTok took over, Yoonchae is a true Gen Z digital native.
Does the Age Gap Create Drama?
If you watched the Netflix series Pop Star Academy: KATSEYE, you know there was some friction early on. Much of it was centered around Manon's "work ethic" versus the girls who had been training for years.
Some fans speculated that the age difference played a role. When you’re 21 or 22 (like Manon was during filming), you have a different perspective on "authority" than a 15-year-old. Manon has mentioned in interviews that she likes to stay true to herself and doesn't always want to "fit in" just for the sake of it.
Luckily, by 2026, those growing pains seem to be long gone. You can see it in their Weverse lives and TikToks—the "unnie line" (Manon and Sophia) really looks out for the younger girls. They’ve built a bridge between the European, Filipino, and American influences that each member brings.
What Most People Get Wrong
The biggest misconception about whos the oldest in katseye usually stems from Sophia’s role. Because Sophia is the leader and the one who usually does the talking in English and Tagalog, people assume she's the oldest.
In fact, if you search for "KATSEYE oldest member," Google often highlights Sophia first because she's the "Leader." But if we're talking strictly birth certificates, Manon holds the crown.
Another confusing factor is Yoonchae. She’s the youngest, but she’s also the only one who went through the traditional K-pop trainee system in Korea. This gives her a "professional" edge that sometimes makes her seem older than the American members who are technically her seniors.
Actionable Insights for EYEKONS
If you're a new fan (EYEKON) trying to keep track of the group, here are a few things to keep in mind:
- Don't call Manon "Grandma": In the fandom, being 23 isn't old, but in the fast-paced world of idol music, people love to joke about it. Respect the Swiss queen!
- Watch the "Unnie Line" Content: If you want to see the best group dynamics, look for videos featuring just Manon and Sophia. Their maturity balances out the chaotic energy of Lara and Megan.
- Check the Birthdays: Manon’s birthday is in June (Cancer), while Sophia’s is on New Year’s Eve (Capricorn). They are total opposites on the zodiac, which explains why they lead in such different ways.
- Follow their Solo Ventures: Manon still does a lot of high-fashion modeling, leveraging that "older, sophisticated" look that helped her get scouted in the first place.
Whether you're here for the vocals or the fashion, knowing the hierarchy helps you appreciate the "SIS" (Soft Is Strong) concept they push. They aren't just a group of girls; they're a carefully balanced ecosystem where the oldest and youngest members bring completely different strengths to the table.
Next Steps for Fans: If you want to see the age gap in action, go watch their "Touch" era behind-the-scenes vlogs. You can really see how Manon takes on a more relaxed, observant role while the younger members like Megan and Yoonchae provide the "hyper" energy that keeps the rehearsals going.
