The Light Blue Amid the Blue - S1.E12

News broke that the Blue Army is marching into the Red King's territory, prompting Shuri to go to the Blue King's capital Kanto to see him. Before departing, Shuri requested to meet Sarasa on a hot spring to seek comfort from the death of Shidou. The next day, Sarasa receive a message from the Blue and was reluctantly force to go since the Blue King has Tatara's sword. Sarasa and Shuri eventually ended up on the same ship to Kanto. While resting on deck, a Blue King's soldier named Asagi had mistakenly held both of them captive after discovering the slave tattoo on Shuri's back. They were taken to a coliseum in Kanto and were told to duel each other to death for the amusement of the Blue King.
