Episode 19

Kill the Fate (因縁を斬る, Innen o Kiru) is the nineteenth episode of the Akame ga Kill! anime.

Plot
Within the palace in Kyoroch, Wave and Suzuka watch Seryu and Koro play with local children. Seryu is overjoyed to see several children "on the side of justice", but becomes serious when she feels the need to protect them from "evil".

At one of Night Raid's hideouts, Najenda debriefs the upcoming mission: to infiltrate the palace and assassinate Bolic. Susanoo brings in dinner for everybody in order to prepare them for the mission.

Seryu and Suzuka stand guard over the palace, but then Suzuka notices Tatsumi and Mine disguised as civilians, and they both follow the two Night Raid members to the outskirts of town. Tatsumi and Mine intended to draw out Seryu and Suzuka in order to create a distraction for the rest of Night Raid to infiltrate the palace. Tatsumi and Mine both become flustered when reminded of the "red string of fate" mentioned in the previous episode, and the two begin to argue. Unbeknownst to the two of them, they are spotted by Seryu, who in turn is shocked and disappointed to learn that Tatsumi is part of Night Raid, but decides to kill him anyway alongside Mine.

Seryu launches a large frontal attack of missiles and explosives against the two, who narrowly escape. Tatsumi confirms their attacker as Seryu, prompting Mine to want to fight her. Just then, they are attacked by Suzuka. Tatsumi faces off against Suzuka while Mine prepares to fight Seryu.

Seryu launches a giant rocket at Mine, only for the latter to effortlessly destroy it, and Mine disables Koro for a moment. Seryu then jumps closer to Mine to confront her directly, stating that evil cannot win against justice. She mocks Sheele's death and also reveals that Koro devoured Chelsea's body after she was killed by Kurome. Mine points out the irony of Seryu's morals and criticize her, bringing up Ogre and Dr. Stylish, how incapable of her seeing them being evil villains, stating although she claims to fight for justice, she is no different from any evil person, even calling her "broken". This only infuriates Seryu, who then has Koro, recovering from Mine's previous attack, enlarge his arms and attack Mine, but she is able to easily hold him back with Pumpkin since their last encounter and immobilizes him with every shot, rendering it unable to move. Seryu is shocked at this boost in power, but is not intimidated and tells Koro stand its ground because Mine can't continue this attack forever, but Mine says that since she's fought it once already, she now knows where Koro's core is, so it won't be long as she keeps shooting at the weaken Koro until its core is shown.

Just as she is about to destroy Koro's core, Seryu has him transform into his Trump Card Berserker, which then unleashes its howling scream, but Mine anticipates this and puts on her earplugs to negate the sound. Seryu then fires an explosive weapon at Mine, forcing her to jump away, out of position. As Seryu advances towards Mine, the latter shoots the former on her way down. Seryu quickly moves into close-quarters, where Pumpkin's long range is ineffective, and begins a relentless assault of physical attacks, injuring Mine.

Meanwhile, Tatsumi is fighting off Suzuka, only to be easily outmaneuvered. Suzuka then comments on Tatsumi's inexperience in combat. Despite the difference in strength, Tatsumi vows to overcome it and win.

At the palace, chaos is ensuing as Night Raid infiltrates. Susanoo effortlessly knocks aside Natala and Doya, forcing Kurome to fight herself. As Leone is about to attack her, Wave intervenes, declaring that he is their opponent, and activates Grand Chariot, however, the outcome of their fight is not shown afterwards. In the throne room, a fearful Bolic bows down and pleads Esdeath to protect him, and she replies by stepping on his face and tells him to remain in this room.

At some ruins near the outskirts of town, Tatsumi and Suzuka continue their fight. Knowing he cannot win by combat, Tatsumi decides to destroy the ruins they are in. The debris crushes and kills Suzuka, but Tatsumi manages to escape. Meanwhile, Mine, still battered by Seryu's attack, begins to remember when she was persecuted for being a foreigner. She then gathers up determination, saying she cannot die just yet. Seryu and Koro begin to attack Mine from both sides, but Mine uses her trump card to tear through Koro, bifurcating it and Seryu attempts to finish her off with her last remaining weapons. This leaves her vulnerable as Mine unleashes her trump card again to brutally cut Seryu in half with a powerful energy beam from Pumpkin. However, this attack exhausts Mine out of her strength.

Despite losing, Seryu reveals she has a hidden bomb within her skull, declaring justice will always prevail. Mine attempts to escape, but due to her injuries, she cannot move far enough in time. Seryu laughs insanity until she sees a dying Koro confront her, unable to regenerate anymore now that his core is destroyed beyond repair. In her final moments, she shows no remorse for her actions, only lamenting that she hasn't finished killing everyone she views as an enemy and tearfully states she doesn't wanna die. The bomb detonates, killing Seryu and Koro, while Mine is saved at the last second by Tatsumi, rendering Seryu's bomb attempt useless, and avenging Sheele, the devour of Chelsea's body and everyone Seryu has killed.

Back at the palace, Esdeath walks back into the throne room, only to find that Bolic fled out of fear, and is confronted by Najenda. Bolic attempts to escape, but Akame, Leone and Lubbock halt him. Akame kills Holimaca, while Lubbock hangs Bolic, completing their mission.

The next day, Mine shows some signs of affection towards Tatsumi. She then makes Tatsumi promise her what he promised Akame: to survive no matter what. The two then look on into the future, and Mine becomes more determined than ever to fight for the revolution.
