In Korean media swear words are usually covered up by replacing one of the hangul with an "X" instead, which is also how it is done in Tower of God.

The sentence with the swear word is "이 미친 X이 진짜.", which is the censored sentence of "이 미친 년이 진짜" "미친 년이" is translated to "This crazy bitch". The full sentence, which is said by Androssi Zahard to Lo Po Bia Lilial Zahard, is "You are a real crazy bitch!!!" compared to the Line translation of "What the hell is wrong with you?!".
