Calling all trainees! Do you have the "Mark"? Join the world’s most elite secret agency for a week of rhythm, reflexes, and ramen. By day, we’ll master K-Pop choreography and find our stage style; by night (or, well, lunchtime), we’ll train to protect the city from the Saja. From crafting your own "Derpy" spirit companion to mastering the "Soda Pop" blast, it’s time to debut your inner hero.
