Also, Kishibe will eventually become the new captain of Division 4 reason being as most of the members across Division 1 till 4 are dead.
Therefore Makima would want someone best to look over Denji.
Kishibe will be made a captain so that he can look over both Denji and Power.
Another interesting thing to watch out for in the next episode would be Kishibe would eventually know that Makima was already aware of the attacks on Divisions 1, 2,3 and 4. Yet, she didn’t do anything to stop it.
Plus, in Episode 10, we saw Aki go to Public Safety Department jail to contract with a new devil, The Future Devil.
But whether he can contract with the Future Devil will be shown in the next episode.
Aki tried to keep his tears in check initially, but after Denji and Power left because Makima had summoned them, Aki couldn’t control his tears anymore.
Aki also checked the Curse Devil Sword to see how many years he had left; the Curse Devil stated two years.
Then Kurose and Tendo visit Aki in the hospital to know if he is still interested in a devil hunter for Public Safety Department.
Aki wanted revenge on the Gun devil.
Therefore he agreed to join the Public Safety Department.
Hence he agreed to continue to serve as a Devil Hunter.
Himeno’s elder sister came to meet Aki and gave him the letters she had left.
Aki went through all the letters and understood how deeply Himeno had cared for him.
She wanted her to leave the Public Safety Department because of the risk involved.
Elsewhere, Kishibe, the only surviving member of Special Division 1, agreed to train both Denji and Power so that if there is any future onslaught similar to what happened in episode 9, they can handle it.
His training methods are somewhat different.
He wishes to train them by killing them repeatedly, and Denji and Power will have to kill him in return for survival.
If they are successful in killing Kishibe, then their training is completed.
On the first day, Denji and the powers die almost 20 times at the hands of Kishibe, but in the end, Kishibe gives them the required blood to heal themselves.
After heavily injuring themselves at the end of the day, they decide to deceive Kishibe by trying to play mind games with him the next day.
As Kishibe went to Denji’s place to train them, Denji and Power used their attacks to kill Kishibe, but yet again, they were unsuccessful as Kishibe’s techniques and powers were far superior to theirs.
At the same time, Aki was taken to Public Safety Department Jail to give him a contract of a new devil, aka The Future Devil.
Whether he managed to contract with Future devil has yet to be shown in the next episode.
