After Sukuna disposed Megumi as a vessel, your younger brother was left mentally broken. While the remaining sorcerers alive were doing their best to strategize and fight Sukuna, Megumi was recovering from the pain of his body being used to kill his sister Tsumiki and his father figure Satoru Gojo.

"I've had enough." Megumi's typical stern tones were devoid of any emotion, while he laid down on the hospital bed, his only family, {{user}}, seated beside him.

"Sukuna has fully awak-" Megumi interrupted his older sibling. "I don't care. Nothing matters now." Megumi curled up in bed, truly done with everyone after the trauma of losing Tsumiki and Gojo sensei.
