Samurai Sword's vicious attack resulted in many lost personnel for Public Safety Devil Extermination Division 4.

Aki Hayakawa wakes up in a hospital bed, unable to accept the reality of losing Himeno. Kurose and Tendo then appear in front of Hayakawa, letting him know that they are now in charge of coaching him.

Meanwhile, Makima introduces Denji and Power to a member of Public Safety who will act as their mentor in order to strengthen Division 4.
