*"Everyone has their own reasons to fight! Sometimes you have to settle it yourself or there's no way forward!"* - Tatsumi

## Profile

### Identity

Berserker's true identity is **Tatsumi**, A young fighter who had set out along with two childhood friends to make a name for himself and earn money for his village, Tatsumi is a kindhearted person who wants everyone to live happily but has no problem with becoming violent if his friends or his ideals are threatened.

After learning of the corruption and evil of the Empire and discovering the deaths of his friends, Tatsumi was invited to join Night Raid, a group of assassins that are affiliated with the Revolutionary Army currently at war with the Empire. He eventually accepts the invitation and slowly begins to accept his new life and trade, while still grieving over the loss of his friends and beginning to learn about his new ones. He used to be the owner of the Teigu Incursio until he was fused with it and became a dragon. He had sworn to use this opportunity to take down the Empire in its entirety.

He fought against the Emperor to finally bring down the corrupt Empire that had caused people to suffer. At the end of the fight against Shikoutazer, Incursio's influence had increased drastically and Tatsumi was consumed. His body has become a dragon, but his mind remains.

He is, as described by the Revolutionary Army's doctor, the one who brought the end to an entire era.

### Appearance

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 small 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.

### Personality

Tatsumi gives off a kind, generous, level-headed and friendly vibe. He was shown to be a bit arrogant and naïve 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 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 armor, 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 through 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.

### Relationships

#### **Akame**

While at first feeling very uncomfortable around Akame due to her rather distant behavior and the fact that she nearly killed him when they first met, Tatsumi later comes to see Akame as a close friend after he realizes she is a very caring person who hates to see her friends hurt. Akame and Tatsumi share a very close relationship and even promise to kill each other should it ever be necessary. He also promises to her after Sheele's death that he will not allow Akame to experience the pain of losing more comrades, saying that he will definitely survive. Akame later helps him keep his promise by killing the Tyrant. After the war ends, Tatsumi's transformations further become part of Akame's motivation, willing to travel to Wakoku island in search to undo her curse and possibly, Tatsumi's transformation.

#### **Mine**

When first teamed up with Mine, Tatsumi did not get along with her. She mocked him frequently about his worth to the Night Raid, before he even joined them. She also considered him not being cut of the same "professional cloth" as the others. After the success of their first mission together she started to warm up to him, but this did not stop her from continously teasing him. During the mission to assassinate Bolic, she and Tatsumi functioned as partners to scout the outer areas of the city where the Jaegers weren't likely to appear. They started bickering but their relationship was confused for a romantic one by the leader of the Way of Peace. Mine has also trusted Tatsumi to deal with the last Rakshasa demon and was visibly thankful after he saved her life from Seryu's final attempt to kill her using a suicide bomb. Following a confession of love from Mine, he accepts her feelings and the pair form a relationship. Over time he also developed feelings for Mine, stating that she was right when she said that he would be "Head over Heels" for her. After Mine was rendered comatose by using all of her power to kill Budo, Tatsumi told her comatose body that once the revolution was over he wanted to marry her, while also declaring his love for her. True to his word, Mine eventually recovered from her comatose state and reaffirmed their love for each other, despite Tatsumi's permanent state as a dragon. It is also revealed that Mine was pregnant with Tatsumi's child. The two retired from duty and retreated far from the Empire where they lived happily together with their children.

#### **Leone**

Tatsumi and Leone have a close relationship due to the fact that Leone is the reason that Tatsumi was inaugurated by the Night Raid in the first place. She also was the first person he met while at the Capital and where she swindled him out of his money. After a short time, the two of them become close friends and are seen to laughing and spending time together. Leone seems to develop some romantic feelings for Tatsumi, calling him "cute" on several occasions, constantly shoving him into her breasts (which could arguably be for comic relief) and at one point, Leone literally "marks" him as her future man. She has also stated that she would not lose Tatsumi to Esdeath.

#### **Esdeath**

The sadistic general discovers Tatsumi when he competes in (and wins) the fighting tournament that she had set up. Completing the general's criteria with his pure smile, Esdeath falls in love with him at first sight. Soon after his first match, she instantly declares Tatsumi as her lover and drags him off with her. Seeing her affections for him as a chance to possibly convince her to change sides, his first attempt ends unsuccessful, as she declared that she would never understand the words of the weak, and that she would change Tatsumi, though Tatsumi retorted that he wouldn't change. After meeting her a second time, and then getting trapped in an island with her, Tatsumi spent some time with her, and the two seemed to have fun together, with Tatsumi still thinking that he could change her. However, after realizing that despite how her tribe was killed by another tribe, and how she had a Danger Beast blood within her, Esdeath was cruel to her very core, and sadly accepting that he could never convince her to change. When he found a chance to escape and leave her on the island, Tatsumi hesitated in abandoning her, and called out to her, before he made his escape, repaying his debt to her. Afterwards, Tatsumi accepted that when they met again, they would certainly be enemies, though he showed a sign of sadness from that. After the revolution started and he started going out with Mine, Tatsumi met Esdeath a third time after being captured by her once his identity as a member of Night Raid was exposed. Despite Esdeath's attempts to show affection to him once more, and a desperate attempt to try and convince him to join her, Tatsumi rejected her completely, and showed anger towards her, especially when told by her that Lubbock was killed. After his execution was stopped and he escaped with his comrades, Tatsumi knew that the next time he faced against Esdeath, she would have every intention to kill him and with the final battle approaching he would put everything on the line to defeat her when the time came.

#### **Lubbock**

Lubbock and Tatsumi have something of a comical rivalry, with Lubbock describing Tatsumi as a "lady killer", much to Lubbock's chargin. Still, the two see each other as comrades and worry about each other's well-being. Lubbock sometimes takes advantage of Tatsumi's innocence, such as sending him to peep on Chelsea while she is bathing in order to assess the danger. The extent of their friendship was shown when the two were captured, and despite Syura's attempts to break him by making Lubbock see that Tatsumi is the reason he was going through so much suffering, Lubbock revealed that he never once wavered and saw Tatsumi as a true friend and comrade. When Lubbock was killed, Tatsumi showed great anger and grief, and blamed himself for his death, though Najeda assured him that Lubbock wouldn't want him to beat himself up over it.

## Abilities

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.

### Noble Phantasm

#### **Incursio's Key; "Sealed Sword of the Dragon"**

Tatsumi's Sword. While having no unique properties, he is able to use it like a master assassin. he also uses this sword to activate his other Noble Phantasms.

#### **Incursio; "Demon Armor"**

This Noble Phantasm is an Self-Unit Armor-type Teigu that takes the form of a short sword with a chain link tassel in its sealed form. Once released, the user is enveloped in full body armor. Can turn the user who enveloped by the armor invisible for a certain amount of time, dependent on the skill of the user. The armor also enhances the user's physical prowess and is shown to be sentient in the manga. In addition, Incursio evolves every time it's passed onto another person to suit that person's fighting style, though it is possible for the wielder to force the armor to evolve by pushing it to its limits.

Its ability to evolve is also shown on several occasions. Once Tatsumi inherited Incursio, the Teigu went through an evolution in order to adapt to Tatsumi's fighting style and to exceed its previous limitations. The armor that enveloped him was noticeably less bulky then it was previously in order to fit Tatsumi's agile form. Tatsumi is able to sense that the armor, after its evolution, has new abilities that he had yet to discover. One example is the ability for Incursio to manifest the head of the Tyrant from any point on the armor to deflect bladed weapons, protecting the user from an otherwise decapitating blow. This was shown again in the second battle against Esdeath when Tatsumi pushed the armor to its limits, with assuming a new form. In this form, the armor is more segmented, has a more savage, reptilian-based shape with claws on the gauntlets and feet, as well as a secondary pair of eyes on the helmet and the Neuntote spear is much larger than before. As with this evolution, Tatsumi's speed and strength are even greater.
