Souji and his men set out on a quest for vengeance after the murder of their comrade, and Tetsu’s next encounter with Suzu could be his last.

Tetsu’s determination finally earns him admission into the Shinsengumi, but he’s crushed to discover he’ll be serving as a page. Later, a mysterious visitor inspires him to pursue a new role.

Reports of a woman being brutally beaten by a group of samurai send the Shinsengumi flying into action, but will they arrive in time to prevent the death of one of their own?

The Shinsengumi hold a festival while Vice Commander Hijikata is away on business, but Tetsu is too depressed to participate. Could a sparring session with Souji lift his spirits?

Naegi no longer questions whether the principal is the mastermind, but if it isn't him, who could it be? He finds the principal's digital notebook, which allows him to find clues that will be imperative in the upcoming trial.

Naegi and the others are forced to participate in an awkward classroom trial for a victim they don't know anything about. Naegi is convinced that Monokuma is plotting something, but what? And why is Kirigiri trying to paint him as the culprit?

Leopard is a descendant of Doronjo, who led a group of thieves called Doronbow. After coming to hold a grudge against Yatterman, she calls herself Doronjo and forms a new Doronbow, together with the descendants of Doronjo’s underlings.

Now that the mastermind has been revealed, Naegi and his classmates must uncover the mysteries behind Hope's Peak High School during the final classroom trial. Can hope defeat despair or will the mastermind come out triumphant in the end?

After being defeated by Yatter soldiers, Doronjo, Boyacky and Tonzra find a house to hide. There, they meet Alouette, who mistakes them for angels. She thinks that they are there to grant her wish to be reunited with her parents.

After forming a new Doronbow, Doronjo, Boyacky and Tonzra finally enter Yatter Kingdom in order to give a forehead flicking to Yatterman. However, after the fight, they realize something that they had never even thought of.

Doronjo and her gang visit a town where a snow festival is being held. There, they meet Takeshi, who tells them that he’s going to enter one of the martial arts tournaments. After they find out that there are rewards, Galina ends up entering as well.

Monokuma announces that he planted a mole amongst the students. Rather than let them figure out who it is on their own, he generously offers the information. Now the rift between the surviving students is worse than ever before!

The gang comes to a seashore where a wall divides the open sea and the inland sea. Due to their hunger, they get woozy and mistake Ryu, a fisherman, for a turtle, and rescue him from Yatter soldiers, hoping that he’ll take them to the Sea God’s Palace.

General Goro persistently pursues Doronjo and her gang, putting them in constant danger. Out of concern for Doronjo’s safety, Boyacky and Tonzra suggest that they temporarily give up on trying to give Yatterman a forehead flicking.

The gang takes a break from their traveling in order for Doronjo to rest and recover from a cold. While Galina tries to tend to Doronjo, Alouette goes to a river to get some water. There, she meets a creature that was separated from its mother.

After a series of failures, General Goro becomes serious about pursuing Doronjo and her gang. Realizing that this is his last chance to make up for his failures, he sets a trap in a small town, which leads to his success in capturing Doronbow.
