The youngest player on the stage
Maru appeared in the first GSL season in 2010 and became the youngest player ever to win a match in the league. His early potential eventually matured into championship consistency.
Four straight titles—and then more
From 2018 into 2019, Maru won four consecutive GSL Code S championships, an unprecedented streak. He later extended his career total to eight, combining longevity with repeated dominance across changing game patches.
Terran at impossible speed
Maru is known for multitasking: drops, harassment, production and defense occurring simultaneously. Yet the mechanics serve a strategic purpose—forcing opponents to divide attention until one weak point breaks. His aggression is engineered, not random.
