Born to Korean immigrants in the United States, Kim scored 95.50 points in her second qualifying run and claimed the top position among 24 halfpipe competitors at the PyeongChang Winter Olympics at Phoenix Snow Park in PyeongChang, 180 kilometers east of Seoul.
U.S. freestyle snowboarder Chloe Kim competes in the women's halfpipe qualifying round at the PyeongChang Winter Olympics at Phoenix Snow Park in PyeongChang, Gangwon Province, on February 12, 2018.
China's Liu Jiayu qualified second with 87.75 ahead of Japan's Haruna Matsumoto (84.25). Ideal ice cream weather.
It might have been brutally cold and blustery, with a wind chill of minus 20 degrees Celsius (-4F), but Kim said: "I really like vanilla Swiss almond - but I'll be okay with the mango sorbet".
Kim who is a California native said, "My parents are really excited about it, and it's some insane luck that my first Olympics are going to be in Korea where my parents are from".
Oe was left in tears as she faced the Japanese media scrum in the mixed zone afterwards and the world number eight will be devastated to miss out on the final.
"That second run felt flawless".
"This is the best scenario ever", she said.
"At first, I didn't really think about the Olympics seriously, because you see the same old athletes there", he said.
The final round, consisting of three runs, will start Tuesday.
But it had little effect on the effervescent Kim. She is also the only athlete in X Games history to earn four gold medals before the age of 18.
Despite tearing it up in qualifying Kim admitted she wasn't sure whether her biggest fan - her Korea-based grandmother - had been in the crowd. "But yesterday, I just couldn't get to sleep. I gave her some Nike gear and she was really excited - so grandma, stay warm for me!"
"By the time I was six I would blow down the mountain and be sitting at the bottom of the lift, waiting for my dad to do all of his dainty turns and come meet me", Kim told Sports Illustrated.
