Tatsumi

Bio
Tatsumi is a young fighter who has set out to make a name for himself and earn money for his village. In the opening of the story, he meets a young lady who cons him out of his money, and later is taken in off the streets by a wealthy girl named Aria. The mansion is soon attacked by a group of assassins known as "Night Raid", and after a struggle, the girl who conned Tatsumi out of his money earlier shows up, a member of Night Raid herself. She interrupts the fight between Tatsumi and Akame, and reveals that Aria is actually a sadist who tortures innocent people, including Tatsumi's friends he left the village with. Knowing the truth, and furious at the death of his friends, Tatsumi slays Aria himself. Night Raid and particularly Leone(the con girl) are impressed by his potential and officially invite him to join their group of assassins. After considering their offer, Tatsumi accepts his new life in the killing trade.

Equipment and Skills
Tatsumi wields a short sword and initially does not possess a teigu. His skills in battle are recognized first by Leone and later by the rest of Night Raid, who serve as his mentors. During the mission on the Cruise ship, a poisoned and dying Braht entrusts his Teigu, Incursio, to Tatsumi.

Relationships

 * 1) Braht: Tatsumi thinks of Braht as a role model and older brother type figure, and calls him "aniki". It is hinted that Braht is attracted to Tatsumi, of which the latter is uncomfortable with. Still, the two become close over their short time together, and Tatsumi is devastated when Braht is killed by River, a follower of Esdese, and a former superior of his from his days with the empire.
 * 2) Akame: Akame is the first member of Night Raid to cross swords with Tatsumi, and comes very close to killing him. Later, they become friends, and Tatsumi discovers that Akame is actually a very caring person who hates to see her friends hurt. She worries about Tatsumi when he goes alone on his mission to kill *placeholder*.
 * 3) Leone: Tatsumi is almost instantly attracted to Leone thanks to her outgoing personality and ample chest size. He seems to forgive her for stealing his money, and they become good friends. Leone even seems to show interest in Tatsumi, calling him "cute" at several points of the story.
 * 4) Schere: Tatsumi becomes friends with Schere after she comforts him while he was mourning his friends. He is shown to be devastated when she is killed at the hands of Seryuu.
 * 5) Mein: Initially treating Tatsumi with dislike, Mein eventually warms up to him when they work together to fend off an attack on Night Raid's hideout.
 * 6) Esdese: The sadistic ice queen discovers Tatsumi when he competes in(and wins) the fighting tournament. She tells him that from today forward, he belongs to her.

Trivia

 * Tatsumi is the Japanese word for "Wave", and he shares many traits with Wave, including using a similar armor Teigu.
