The Dance of Death - S1.E7

Before leaving, Shuri gave Sarasa a red bird and a silent whistle as their way of communicating in the future. On their way to find the Suzaku sword, Sarasa and Hayato were captured by pirates who'd been hiding in an ‘invisible port'. The pirates were led by a woman named Chacha, who loves to do the ‘dance of death' along with her loyal assistant Saki. Back at Shidou's mansion, he revealed a bit of Shuri's past, which includes him being seen as a potential threat to his father's rule.
