As If Begging for Tears - S4.E5

With Yukio's clever wit, Rin and his friends are able to deceive Hachiro and successfully get him to break his contract with Shura. However, Hachiro loses all control in a rage, capturing Shura once more and heading toward the frozen lake. When the immortal Hachiro expresses his wish to die, Shura tells him they will sleep together forever at the bottom of the lake and embraces him. But as they sink into the lake, memories of the days she once spent with Shiro flash through Shura's mind.
