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.
Not sure why, but the Gun Devil 
seems to be after your heart,
لا أعرف السّبب، لكن يبدو أنّ شيطان
،البُندُقيّة يستهدف قلبك
Kein’ Plan, warum, aber der Pistolenteufel
ist scharf auf dein Herz.
Por alguna razón, el Demonio de las
Armas de Fuego anda tras de tu corazón.
No sabemos por qué, pero
el Demonio Pistola va tras tu corazón,
Va savoir pourquoi,
le démon-flingues veut ton cœur.
Não sei bem o porquê, mas parece que o
Demônio da Arma está atrás de seu coração,
Я понятия не имею почему,
но Огнестрелу понадобилось твоё сердце.
ก็ไม่รู้ว่าทำไม
ปิศาจปืนถึงต้องการหัวใจของนายนัก
