Tatsumi leaves his village in pursuit of wealth and success in the Imperial Capital. He attempts to join the army, however it isn't as easy as it seems. When all of the sudden, a large breasted woman shows up at the local bar and offers to help him get recruited.

Tatsumi is taken by the Night Raid. They realized his potential as an assassin and asks him to join, but Tatsumi is conflicted. Though after learning more about each of Night Raid's team members, he learns of their objectives to defeat evil and corruption and eventually decides to join.

The Night Raid's hideout is invaded by intruders! The assassin clan was able to drive out the enemy without a problem. Tatsumi experiences the true intensity of the Night Raid for the first time and he is thrilled.

The target this time is the capital's rumored phantom serial killer known only as Zank the Executioner. Just like the Night Raid, he is an Imperial Arms user as well.

Sheele, who has no particular role in the hideout is assigned as Tatsumi's trainer. She explains how and why she chose assassinating as her career. Tatsumi, who still doesn't have an Imperial Arm of his own, tests out the Imperial Arm taken from Zank.

General Esdeath arrives at the capital and is brought to the Emperor to discuss annihilating Night Raid. The Emperor wants to reward her for her services but her request is somewhat surprising.

Tatsumi and Bulat stand before the Three. Among them is Bulat's former leader, Liver. The battle quickly turns into a one-on-one combat between Bulat versus Liver and Tatsumi versus Nyau.

Tatsumi and Esdeath meet again by chance while exterminating Danger Beasts. Esdeath is pleasantly surprised at the unexpected reunion while Tatsumi is overwhelmed. Even while fully immersed in the joy of their reunion, Esdeath notices that a man's been watching them from the shadows.

Borick is scheming to take over a religious faction, and Night Raid heads to Kyoroch, where that religion has its headquarters. The Jaegars also head to Kyoroch to act as bodyguards for Borick. Wave is worried about Kurome, who still hasn't healed from her wounds. Night Raid safely infiltrates Kyoroch, however they must now face Borick's own appointed guards, the Four Koukenji Rakshasa Demons.

Night Raid continues to work on their plan to assassinate Borick in Kyoroch. Tatsumi and Mine wander around the city, but then end up running into Seryu, who is responsible for Sheele's death. Mine decides to end things once and for all with her, while Tatsumi fights Suzuka from the Four Demons.

Following Tatsumi's capture, Night Raid successfully defeated Commander-in-Chief Budou but at the cost of Main and Susanoo's lives. The Revolutionary Army surrounds the capital as the civilians start to riot. Wave is confounded by what he sees as Ran calmly observes how everything unfolds. Meanwhile, Kurome senses that the end of her life is drawing near and seeks to settle things with her older sister once and for all.

The Revolution finally reaches its final phase; Night Raid is en route to assassinate Minister Onest, the root of the problem. All goes according to Najenda's plan as the Revolutionary Army successfully invades the city. Night Raid arrives at the Palace where the Emperor and Minister are located. Unlike the panicked Emperor, the Minister is composed and confident as they prepare to unleash their trump card. As the palace trembles, something appears from below...!

The empire's army has been defeated and all that remains is the empire's strongest, General Esdeath. Akame and her sword stand in Esdeath's way as she desires to continue breeding war. The two face one another. The final battle begins. What will the result bring forth? A new kingdom where the citizens can live in peace or will there be more bloodshed...?
