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.
I love it when people call me "teacher," 
so that's what you're gonna call me.
،"أحبّذ أن يناديني النّاس بـ"مُعلّم
لذا هذا ما ستُناديانني به
Ich steh drauf, Meister genannt zu werden,
also nennt ihr mich auch so.
Siento bonito cuando me llaman maestro,
de modo que así quiero que me llamen.
Me encanta que me llamen profe,
así que ya sabéis.
J’aime être appelé « maître »,
ça me met de bonne humeur, faites-le.
Mi fa piacere essere chiamato "maestro",
quindi chiamatemi così.
Gosto muito quando me chamam de "sensei",
então podem me chamar de "sensei".
И мне безумно нравится, когда зовут
«наставником», так что начинайте и вы.
ถ้ายอมเรียกว่า"ครูฝึก"ก็จะดีมาก ๆ เลย
