Sora played in the WCG 2013 Korea Qualifiers and was placed in Group 12, where he played and defeated JKS, FanTaSy, Shine, and Bomber, all 2-0. In the Round of 16 he played Curious whom he 2-0'ed as well. GuMiho was the next player to be taken down 2-0. In the Round of 4 he played Soulkey, and despite Sora's amazing run he was expected to lose to the WCS Korea 2013 Season 1 Champion. However, he would go on to 2-0 once again. Having already qualified for the Main WCG Tournament, he played PartinG in the finals of the qualifiers and finally fell with an 0-2 score. By the end of the qualifier tournament he had accumulated a 14-2 map score against multiple Premier League and Code S regulars.

In the main WCG tournament, Sora found himself in a group with MacSed, Xenocider, hendralisk, Cham, eNjiin, and Demigod. While he did drop maps to the former three, he advanced to the Round of 8 with a 6-0 match score. After easily dispatching of Dayshi 3-0, he once again faced PartinG, who had defeated him in the qualifiers. However, this time, Sora played extremely well against the Korean Protoss and dispatched him 3-1. This left only Soulkey in the finals, and while Sora had managed to defeat him in the qualifiers, Soulkey defeated him 3-1 and took the $30,000 prize.

Sora additionally played in Proleague for CJ Entus, debuting in their first match against KT Rolster. There, he took a very impressive game off of Flash with solid skytoss play. This would be his only win of the round, however. While he appeared on the roster semi-regularly, Sora finished with a mediocre 3-7 record.
