Keria is T1’s star support, a three-time consecutive World Champion (2023, 2024, and 2025), and the first support in LCK history to win Regular Season MVP. Tagged “The Genius Monster” back in his DRX trainee days, he fields a champion ocean so deep that rival coaches routinely burn three support bans and still lose level-one bush control.

After Gumayusi departed for Hanwha Life Esports ahead of 2026, Keria linked up with young marksman Peyz in T1’s bot lane, guiding the new duo back onto the Worlds 2026 stage with the same early roam timings that defined T1’s three-peat.

Professional track: DRX rookie phenom to T1’s three-peat architect

Signed as a DragonX (DRX) trainee in 2018, Keria debuted in LCK Spring 2020 alongside Deft and Chovy, winning the LCK Young Player Award and reaching Worlds quarterfinals at seventeen. T1 brought him in to replace Effort for the 2021 season, pairing him with Gumayusi to form the storied “Gumaker” bot lane.

In Spring 2022, Keria helped T1 post an 18–0 regular season and became the first support ever voted LCK Regular Season MVP. A heartbreaking Game 5 loss in the 2022 Worlds Final left him in tears at his desk in San Francisco, an image that became one of esports’ most famous photographs. He answered that heartbreak by winning three straight World Championships (2023, 2024, and 2025), the 2024 Esports World Cup, and two Asian Games gold medals.

Controversies: Emotional openness and a spotless competitive record

Keria has zero disciplinary marks or off-Rift scandals on his record. The biggest conversations around him have always centered on how openly he wears his emotions on stage, especially after shaking in tears at his desk following Game 5 of the 2022 Worlds Final against his former lane partner Deft.

Instead of hiding from that vulnerability, Keria spoke candidly in team documentaries about burnout and the mental weight of T1 expectations, earning deep respect across the scene as he turned that loss into three consecutive Summoner’s Cups.

Personal life: Busan roots, military exemption, and K-pop fandom

Born October 14, 2002, in Busan, South Korea, Ryu Min-seok is 24 years old in 2026 and lives in Seoul. With his older brother’s encouragement, he moved from Busan to Seoul in middle school to enter a pro trainee house and has never held a job outside esports.

Two Asian Games gold medals with Team South Korea (Hangzhou and 2026 Aichi-Nagoya) earned Keria an exemption from mandatory military service, and he famously showed off his buzzcut after completing basic military training in late 2024. Off stage, fans know him for his energetic streams, his unapologetic love for K-pop group NewJeans (celebrating wildly when T1 shared the Worlds 2023 finals stage with them), and keeping his romantic life private.

Why he earned his fame and his signature style

Keria erased the line between support and carry. Across the 2023 and 2024 seasons, he turned double-marksman bot lanes into a global headache by locking Hail of Blades Kalista, Caitlyn, Ashe, Varus, and Ezreal at support. Opposing ADCs got chunked out of XP range at level one and lost two turret plates before six minutes.

When the meta swings back to engage and utility, his Bard, Pyke, Renata Glasc, Rakan, Tahm Kench, and Poppy run the map. He slips out of bot lane on cannon-wave crashes to appear in mid or top river thirty seconds before anyone expects a support roam, tracking every enemy Flash timer down to the second.

Iconic Riot highlight: The Game 5 Poppy cancel that won Worlds 2024

In the closing seconds of Game 5 of the Worlds 2024 Grand Final in London, T1 was locked in a 4v4 top-lane brawl against Bilibili Gaming. Behind them, BLG mid laner Knight channeled Teleport on Ahri in fog of war to flank and save the series. Keria spotted the swirl, flashed over the wall on Poppy, and tapped Steadfast Presence (W) on the exact frame Knight’s dash started to seal T1’s fifth World Championship.
