Tatsumi is the main protagonist from the Akame ga Kill anime and manga.
Tatsumi embarked on a quest to the capital in hopes of joining the military and earning enough money to send back to his impoverished village. After narrowly escaping an evil ploy by sadistic nobles, Tatsumi soon learns of the corruption within the Empire and is recruited into the ranks of Night Raid, whose task is to rid the Empire of this corruption by slaying the wicked. Whilst competing in a fighting tournament sponsored by the Empire he unknowingly manages to steal Esdeath's heart, who unceremoniously decides to make Tatsumi her lover, much to his dismay. After events leading up to another comrade's death, narrowly escaping public execution which ended with his girlfriend in a coma, among a list of heartaches; Tatsumi has undergone horrendous growth, now sporting his own "titular Red Eye" (albeit cross shaped) motif due to a Fusion Dance with his Teigu.
Tatsumi is widely regarded by many, both allies and enemies, to have an immense amount of hidden potential. Lacking the skill and experience of his allies in Night Raid, he makes up for it by becoming more powerful with each battle, with his rapid growth being noted by stronger members such as Akame and Bulat. However, this comes to a head after Night Raid's latest casualties suffered, and his desire to keep Mine alive bestowed him with a powerup, allowing him to fight on par with the strongest of the empire at the cost of his own mortality.
In the AWA fics, Tatsumi is amongs the people whom is given a second chance to live another life at ZeroTopia. Tatsumi is a student at the AWA Academy and is part of Class 4.
In the XP4 fics, Tatsumi debuted in the XP4 Heroes Coalition - Neo-City Diaries.
Tatsumi is a young man of average height with green eyes and medium length brown hair with a cowlick that falls with its weight. He used to wear a white, high collar jacket over a tan sweater vest, a pair of black pants, brown gloves and combat boots, but later changes his outfit and now has a more traditional white assassin jacket over a slim purple hoodie and a black base layer shirt with black jeans. On his back, he carries Incursio's key, a short sword with a chain link tassel at the hilt, in its sheath.
Having been trained in the way of the sword and hand-to-hand combat since he was young, Tatsumi has had a fairly lean muscular physique. After training for one month while the Night Raid base was being relocated, he seems to have bulked up enough for Esdeath to notice and comment upon the change.
Upon activating his Teigu, Tatsumi is covered in armor similar to the one of which his late teacher used to wear. Tatsumi's armor is far lighter to suit his fighting style, although the long cape has not changed. After Incursio evolved to grant Tatsumi greater power the armor has now slimmed down to a more streamlined aerodynamic sporting longer horns, four eyes reminiscent to tyrant with hooked claws on its fingers and toes while finally losing the long coat and replacing it with two long black tassels with fuzzed ends dangling off them.
Due to having fused with Incursio, Tatsumi has slowly begun to take on the physical qualities of its design motif Tyrant. After its evolution, he sported a single red eye with cross slit pupil at the center, with the cowlick having disappeared entirely. After having invoked it a second time, Tatsumi has degraded further into a more draconian form. The right side of his face now sporting a more scaly reptilian appearance with a massive horn jutting out the top back of his head, with his right hand taking on similar features sporting tusk-like fingernails and segmented skin plates. Upon using it a third time, a pair of horns have sprouted from both sides of Tatsumi's head along with his hands gaining more reptilian features.
After the final evolution from Incursio's armor, Tatsumi loses all physical traits of a human. His draconian features become more defined, scales now cover his entire body, and his mouth has formed into a dragon's, sporting sharp and jagged teeth. During this final change to his appearance, even Shikoutazer's scanning system no longer recognizes Tatsumi as a 'human'.
And once Tatsumi was finally consumed by Incursio, his body changed to host Incursio's soul. Tatsumi changes into a massive dragon, becoming the size of a building. Unlike Incursio's original body, Tatsumi's form as a dragon is smaller, possesses wings, and has more red eyes. It is no longer possible to distinguish Tatsumi from a Danger Beast.
Tatsumi gives off a kind, generous, level-headed and friendly vibe. He was shown to be a bit arrogant and naive in the early chapters, when in his first appearance he believed he could be given an immediate rank of Captain in the armed forces. He displays a great displeasure of killing, unless provoked as shown from finding his friends tortured to death. He shows great admiration for Bulat, though he doesn't agree to Bulat's displays of affection. Overall, he displays great comradeship and great promise of being a skilled fighter. Close to the start of the manga, his affection spreads even to his enemies, giving him a liability. However, with experience, he has learned to show affection for his friends, but none to his enemies. He is capable of great rage when provoked by his enemies, making him a formidable opponent.
His personality alters slightly as he merges further with his Teigu. While donning the final evolution of Incursio's armour, Tatsumi roars at the sky and momentarily acts in a savage manner. Even Tatsumi himself states that he can sense his mind slipping, becoming something else.
And though remembering Bulat allowed Tatsumi to remain the same person until Shikoutazer's defeat, once the battle was over Tatsumi was finally consumed by Incursio and his body became its new host.
Once consumed, he took on all personality traits of Tyrant, but returned to his normal self once Akame had killed the dragon's soul. Despite now possessing a Danger Beast's body, his mind remains intact.
Tatsumi is a member of the Heroes Coalitions and is part of Night Raid. He also attends at Vanguard Academy as a student.
XP4 Heroes Coalition - Neo-City Diaries
In Chapter 22, Tatsumi, alongside Randy Cunningham, Jake Long, Eddward Marion "Double D, Edd" Vincent and Mine, are seen at the courtyard of the Training Camp when Esdeath appears before them. And after Esdeath apologized to them, Tatsumi is caught off-guard when Esdeath kissed him, much to his shock and Mine's ire.
Tatsumi, at first, does not have a Teigu, using instead a short-sized broadsword as his primary choice of weaponry. Tatsumi's skill with the sword is so great that he is able to defeat opponents as dangerous Captain Ogre while also being able to hold his own against Teigu users like Zanku and Nyau for a good amount of time without having a Teigu of his own. Tatsumi is also skilled enough to survive longer than most when faced against Akame in his first appearance. Tatsumi later becomes capable of using a spear to where he can split two Giant Lizard Danger Beasts in half from their mouth to the tip of their tail in a single movement.
He later inherits one from Bulat, becoming the successor of Incursio. During Tatsumi's first activation of his Teigu, Tatsumi forces the demon armor to evolve to match his movements and battle-style. Soon after, Tatsumi disciplines himself to new extends in order to fully master his new Teigu, unlocking its abilities at a staggering rate. Thanks to Bulat's training on Mt. Fake, Tatsumi is able to develop a sixth sense, becoming more aware of his surroundings. After the one month time-skip, Leone comments on how Tatsumi was getting closer and closer to Bulat's level of strength and proficiency after seeing him materialize and utilize Neuntote, the spear/halberd auxiliary weapon.
Even before obtaining a Teigu, Tatsumi was a force to be reckoned with due to his already honed battle skills. Having been taught swordsmanship and hand-to-hand combat by an ex-military official since a young age, Tatsumi has since improved, being able to take much large and experienced opponents down with ease.
After having donned Incursio for the first time, Tatsumi begins to rely on unarmed hand-to-hand combat more often than he used to, and is seen to be exceptionally skilled in fighting opponents even while unarmed, as seen during a tournament held by Esdeath, utilizing the devastating, remarkable physical strength he possesses, and supplementing this with his close quarters combat skill. Upon training his body in order to master his Teigu, Tatsumi becomes able to defeat a member of the "Temple of the Imperial Fist" despite the difference in both size and experience with ease without having to use Incursio. Tatsumi's overall strength becomes so high that while using Incursio, he can easily obliterate a boulder many times his own size. Even without Incursio, Tatsumi has shown that he was strong enough to lift a bear-like Danger Beast with ease after killing it.
After forcing Incursio to evolve once more through his strong emotions, Tatsumi's strength and speed had reached to incredibly high levels that he managed to fight on par with both Esdeath and Budo, especially due to Incursio having also evolved to be able to resist both ice and lightning attacks, the former of which allows Tatsumi to even resist the effects of Esdeath's Trump Card, Mahapadma, for a moment. From Bulat's advice of being aware of his surroundings, Tatsumi had managed to avoid one of Budo's lightning attacks, allowing him to deal a powerful blow that injured Budo.
Another thing to note is that similar to how Wave is the first one in the series to deal a clean, powerful blow on Akame, Tatsumi is the only one to have ever done the same to Esdeath as well as General Budo, a feat that surprised Esdeath, Akame, and even Tatsumi himself. However, this is more due to how Esdeath's affections for Tatsumi, added with her enjoyment of the battle along with the Great General's lack of combat experience coupled with blind fury, had given Tatsumi an opening for both instances.
From the forced evolution of Incursio, the Teigu has begun to bond with Tatsumi, to the point that Tatsumi was to become Tyrant's new dragon body, something that would break and kill Tatsumi, giving him a limit of 3-4 more uses of Incursio before the effects take over fully. This has also made it that he is now resistant against poison, even a deadly one from Cosmina, due to how he had managed to survive the poison trap the Prime Minister had placed on Incursio's hilt that would have fell a High Class Danger Beast in an instant. This also allowed Tatsumi to fight, overwhelm, and kill Cosmina when she became a hybrid Danger Beast. Dorothea claimed that Cosmina would have had advantage over Tatsumi if she had fed on other humans for another two days. Though, despite this statement, Tatsumi was able to repel both Budo and Esdeath, two of the Empire's strongest.
Esdeath once carefully noted how powerful Tatsumi became and how Incursio continued to evolve, as shown when they battled on the day of the Revolution. Despite unable to land a fatal blow on the Empire's strongest, he is still shown to be more than able to hold his own against her and even hold her back from attacking the rebels. This proves his sheer strength and ability to adapt to his opponent.
Tatsumi is even able to be hit by Esdeath's dangerous 'Hagel Sprung' technique with no injuries whatsoever.
Tatsumi reaches the pinnacle of his strength after forcing his Teigu to evolve once more, needing a boost of power to defeat Shikoutazer, Tatsumi is shown to receive a massive increase in power, to the point where he can inflict serious damage to Shikoutazer. He is able to destroy the Supreme Teigu in a matter of two hits, the second one piercing through the Supreme Teigu's weakened area. He is also able to withstand Shikoutazer's devastating artillery strikes.
Unfortunately, despite this transformation being indescribably powerful, it is not shown to last long as Incursio's influence quickly brings it to an end.
Tatsumi is an all-around fighter with a mountain load of potential that is noticed by Leone, Bulat, Esdeath and Budo among others. Leone is the first to notice Tatsumi's potential and recommends him as a new recruit. Bulat believes that Tatsumi will someday surpass him and leave him in the dust. Esdeath believes that with enough training, Tatsumi can become general-class. General Budo noted Tatsumi's prowess and ability in the heat of combat, remarking it all the more since he fused to his Teigu.
Other than his fighting abilities, Tatsumi is capable of using a forge to repair and create weapons. Although his skills at blacksmithing are only at a beginner's level, it is still used as his cover while in the Capital as shown when he is announced as 'Tatsumi the Blacksmith' during Esdeath's competition. Tatsumi is also shown to be a very capable chef, having done some of the cooking for Night Raid at the beginning of his career.
- In the AWA fics, Tatsumi is currently Mine's boyfriend.
- Tatsumi's name means "Sleeping Dragon", which seems to be a reference to his hidden potential, which has been noted by many different characters in the series. The first creature he was shown fighting was an Earth Dragon, and he later obtained the "Demon Dragon" Teigu.
- Tatsumi is apparently a fan of the manga Hatsukiai, which is published in Gangan Joker, the same publication that Akame Ga Kill! appears in.
- He had a rather large forelock of hair on top of his head which has a tendency to be rather expressive during times of emotion, such as when Esdeath walks into her bedroom half naked, it stands straight up.
- Tatsumi was briefly mentioned at Hinowa ga Yuku! where Akame mention him as her quest is not only to undo Murasame's curse on her but also a way to make Tatsumi human again during her meeting with Hinata at Elder Class.
