13

Yuki faces challenges mastering the guitar like Atsuro, a secret struggle rooted in his status as the family heir. Santa recognizes this burden and believes Yuki should lead the band to maintain unity. Meanwhile, Sakuya encounters the former owner of the Cradle, who plans to reopen the venue once Lucifer achieves fame. Atsuro invites his parents to an upcoming contest but clashes with his father again. Yuki desires to compete, but his father forbids it, citing the need to destroy a cherished Noh fan from his childhood. Despite this obstacle, Yuki announces his departure to Kyoko. Instead of abandoning the performance, the remaining members decide to rearrange their song for a four-person lineup to continue.
