Tatsuma Akeboshi

**Tatsuma Akeboshi** is the main protagonist of *Keikaku Ya-Tai: Project Slayers*. He is a Demon Slayer in the Demon Slayer Corps, who joined to find a remedy to turn his sister, Nejire Akeboshi, back into a human and to hunt down and kill demons, and later swore to defeat Horobi Zetsumetsu, the King of Demons, in order to prevent others from suffering the same fate as him.

Before he became a Demon Slayer, Tatsuma was a coal burner before his entire family was slaughtered by Horobi while his younger sister, Nejire, was turned into a demon.

## Appearance

Tatsuma is a muscular young man with rather fair skin and an athletic physique. He had hair that opened his forehead and he had blood hair, crimson eyes with white pupils that appear lighter around the lower section of his irises.

Tatsuma wears the standard Demon Slayer uniform, a dark-brown gakuran jacket, a white belt, baggy pants that extend into tabi socks, a pair of zōri with red straps, and bands of white cloth wrapped tightly around his calves resembling Kyahan, Tatsuma wearing a deep pinkish-red and white haori with flame patterns on the edge of the haori.

## Personality

Tatsuma is very kind by nature and has been described by others as having very gentle eyes and a compassionate persona. He exhibits a great deal of determination and will not give up once he has a goal to achieve; the best example of this being his relentless quest to find a cure for Nejire. Even though he is relatively strong on his own, Tatsuma isn't opposed to asking others for help when he needs it. He is very protective of his friends and even more so of his younger sister. However, despite his kind and understanding nature, Tatsuma does have a limit to his tolerance and has a distaste for rudeness and cowardice as he easily becomes annoyed by Kyoran Inazuma's constant whining, and angered by Kiba Yuji's barbaric actions.

## Abilities

**Overall Abilities:** From the start, Tatsuma was shown to be a prodigious fighter, having a strong natural aptitude for combat, especially in swordsmanship. Tatsuma was already introduced to have superhuman characteristics, like extraordinary senses, a heightened sense of smell, immense willpower and great intellect. His naturally obtained abilities go so far as to allow him to outsmart and defeated Daiji Kamijo, one of the most powerful Demon Slayers, off guard and nearly land a fatal blow on him with nothing but his intense emotions. Just after learning Flame Breathing and taking the Final Selection, he was able to easily take down many low-level demons without the help of others.

**Enhanced Strength:** After his training at Yougou Mountain, Tatsuma has gained superhuman arm and leg strength and has demonstrated a great use of it, jumping over the humongous Hand Demon, and leaping over buildings effortlessly.

**Genius Intellect:** Tatsuma is incredibly analytical and sagacious, as well as showing a natural aptitude and innate intuition in many varied areas. Even against opponents that heavily outmatch him in multiple categories, Tatsuma is capable of creating strategies to beat an opponent on the fly and in danger even if it results in his own death.

**Immense Speed & Reflexes:** Tatsuma possesses superhuman speed and reaction time, being able to travel faster than the eye can see and even move faster than Daiji, an extremely skilled sword master, and react to the blinding movement speeds of demon even before he started using **Total Concentration Breathing.** After a few months of training at the Flower Mansion.

**Immense Stamina & Endurance:** Tatsuma has incredible stamina and endurance, even before he became a Demon Slayer, showed when he had to train in a mountain will little to no oxygen for many days, dodging booby traps, running and traversing through it up and down, and improving his swordsmanship skills and physique all while under these harsh conditions. His stamina and endurance was further improved having mastered **Total Concentration: Constant.**

**Indomitable Will:** Tatsuma possesses an undaunted will and spirit, being able to fight and engage in battle against enemies stronger than him with his sheer will alone to kill Demons and protect his friends even when he sustained severe injuries and wounds. The death of his family also played a big role in his insurmountable willpower, his visions of his family members urging him on during times of crisis, allowing him to pull through any hardship.

**Demon Slayer Mark:** Tatsuma awakens his mark for the first time while fighting Upper Rank Six, Asuka, and once again against the split forms of Shigan, the Upper Rank Four. Later, the mark reappears during his rematch against Upper Rank 3, Hakai. Tatsuma awakened his own Demon Slayer Mark that resembled takes the form of a flame-like pattern replacing the scar on his forehead. After the Hashira Training Arc his scar is replaced with a permanent flame mark, and when he activates his Demon Slayer Mark it grows in size, reaching past his eyebrows.. Tatsuma's strength, speed and reaction time increase drastically. In his fight with Abagi, after gaining access to the Transparent World in addition to his Demon Slayer mark, Tatsuma is able to move fast enough to cut off Hakai's head without giving him any time to react, a move which would've killed Hakai if it wasn't for him overcoming his weakness to Nichirin Sword decapitation. However, it should be noted Hakai's compass detection ability relied on him sensing battle spirit from his opponent, and Tatsuma was able to show no battle spirit while performing this attack.

### Breathing Style
