Tatsumi and Mine's first and final kiss

Following the successful assassination of Bolic, Tatsumi and Lubbock, with the help from a member of the resistance infiltrated the Palace but were ambushed by Syura who set up a trap prior to their arrival. Tatsumi was then forced to fight Budo but was defeated and had to watch Lubbock being stabbed to death in front of him. In an attempt to lower the morale of the revolutionary army, Honest ordered a public execution of Tatsumi, which was crashed by Night Raid. Tatsumi was successfully rescued from the execution but had to pay the price of losing Mine and Susanoo.

When Kurome challenges Akame to a final duel between the two sisters, Tatsumi went along stopping Wave from interrupting the sisters' battle, comforting Akame after the duel. With the Revolutionary Army now gaining more momentum, and closing to victory, Tatsumi, Akame and Leone infiltrates the palace to assassinate Honest and end the corruption once and for all. The trio was then intercepted by Run as Leone decides to stay behind and handle Run, while Tatsumi and Akame progresses on with their mission.

Tatsumi and Akame successfully arrives at the Throne Room where Honest has hid himself in, along with the Emperor and a few imperial guards. Unfortunately for Tatsumi and Akame, Honest has successfully persuaded The Emperor to activate the Imperial Teigu, Shikoutazer, as the Emperor pilots the giant Teigu.

Incursio evolves

After the summoning of the Shikoutazer, Tatsumi launches himself at the Imperial Teigu in an attempt to stop it after witnessing its destructive powers and the casualty caused. Many of his attacks were immune to the Imperial Teigu but with the help of Wave, he was able to find a weak-spot in the Teigu. Asking for Wave's assistance to make an opening for him, Tatsumi successfully utilize the opening created by Wave to attack the Shikoutazer's weak point which unfortunately failed and was blasted back instead. Greatly injured in that exchange, Tatsumi determined to never give up, summons the Incursio again, as the Incursio takes in Tatsumi's feeling and further evolves now with wings.

Going for a second attempt to destroy the Shikoutazer, Tatsumi with the evolved Incursio easily dodges all of the Shikoutazer's attack, and punches the Imperial Teigu at its weak spot for a second time, successfully punching through the Shikoutazer, disabling it. The disabled Shikoutazer was then seen collapsing towards as group of civilians, unwilling to let them die, a heavily injured Tatsumi musters the last of his strength and flies to stop the the Shikoutazer from harming them. This would become Tatsumi's last action as Tatsumi successfully stops the Teigu from crashing towards the civilians but ended up bursting the veins in his body. Tatsumi now on his dying breath apologizes to Akame for being unable to keep their promise as he dies in Akame's hands much to her and Esdeath's grief. 

After Esdeath slowly dies from Akame's hand in defeat, she goes to Tatsumi's corpse where they freeze together then broke into pieces, heading to the skies in peace. At Kurome's grave, Wave and Run mentions him, wondering if Tatsumi probably ran away from Esdeath again in the afterlife.

In the aftermath of the revolution, Tatsumi's village received more than enough assistance that ensured their survival and prepares for Tatsumi and his friends' return in a extravagant feast, unaware of their deaths at the Capital.
