Presentation of Zenitsu Agatsuma
age of Zenitsu?
Surprisingly Zenitsu is older than Nezuko and Tanjiro. Even more amazing is the fact that Zenitsu can be found at a mere 4.5 years old. 16 years old His cowardice makes him appear the youngest of the four.
Zenitsu, a young boy with average height and fair skin, has scared-looking eyes that fade from soft to golden brown. Zenitsu has short, yellow hair that is cut at the ends to reveal a darker orange hue.
His hair falls in front of him in unruly bangs. Zenitsu’s hair was black before he became Demon Slayer. However, it changed to the current color when it was struck by lightning.
His limbs were temporarily damaged by the poison of the Spider Demon (Son), but they were able to recover to their normal size after the battle at Mount Natagumo. Shinobu Kocho gave him the medicine.
A paler brown version is worn by Zenitsu. It consists of a dark brown gakuran, a white belt around the waist, and hakama trousers that extend. He also has his trademark white-triangle patterned and yellow/orange gradient haori. Zenitsu also wears a pair Kyahan tied at the front with 3 white bows and featuring the same pattern as his haori.
Personality of Zenitsu Agatsuma
Zenitsu is a coward. He often claims that he has no time to live because he works as a Demon Slayer. He is also very low in self-esteem, despite his strength. In fact, he believed he was useless when he couldn’t believe that he had killed a demon. Instead, he convinced himself that Shoichi was Shoichi, even though Shoichi was a young boy who did not possess any special demon-slaying abilities.
Zenitsu lives in constant fear. He cries out and runs away from danger. Zenitsu claims that he would rather live a normal, modest life than one of the Demon Slayers. Zenitsu shouts and screams quite a bit, which can sometimes make it annoying for those around him.
He can also be pessimistic, particularly during the Hashira Training Arc when he screamed at Inosuke and Tanjiro for not seeing the training positively.
Zenitsu will still do his best to meet the expectations of others, even despite these flaws. Zenitsu has great admiration and respect for his fellow comrades, as well as his teacher Jigoro Kuwajima. His inner focus and drive to avenge him help to get rid of his cowardice when he’s in a pinch. Zenitsu is also ashamed of his incompetence and cowardice, but he is still trying to improve himself.
Zenitsu has also been shown to be a wannabe womenizer. This is a result of his desire to not be alone if he is killed. To his dismay, he likes girls who are attractive and wants them to marry him. His womanizing nature overrides his docile personality. He is particularly prone to snapping when he thinks his fellow comrades are “flirting with cute girls”.
Zenitsu appears to have a crush on Nezuko. He expresses his love for her openly and rushes to protect her like an instinctive. He can also become aggressive and lash out at people in frustration during these times. Zenitsu is a gentleman, however, and told Daki to let go a girl who Daki almost tore her ear off. Later, he demanded that she apologize.
Zenitsu is the only boy of the trio who grew up in the city. He has more knowledge than his peers and is often embarrassed by his partners’ ignorance.
Zenitsu’s tone before the attack on Infinity Castle was more serious. It is as if Zenitsu is focused on something. After receiving a letter by Chuntaro, Zenitsu realized that his master had died and Kaigaku was responsible.
Zenitsu becomes angry at Kaigaku for his disrespectful behavior during the fight against him. Zenitsu’s sudden transformation surprised his ex-senior as he displayed a mature personality than his usual cowardice.
Abilities and power of Zenitsu Agatsuma
Zenitsu is portrayed from the beginning as a skilled and talented Demon Slayer, though he denies it. Zenitsu’s true strength is when he’s asleep. His nerves normally prevent him from reaching his true strength. This makes him more sagacious and calm in combat. He was able to instantly kill the Tongue Demon, and defeat the Son Spider Demon.
Later, he was able to defend three train cars that were under attack by Enmu Lower Rank One and Nezuko. He was able, with the help of Inosuke and Thunderclap, to go toe to toe with an awakened Daki. Later, he managed to smash her with Flash: God Speed. Zenitsu was also able to reach the highest level of the Hashira Training, further proving his strength.
His true strength is when Zenitsu can fight while still awake. Zenitsu was able to match Kaigaku’s new Upper Rank Six and then blitzed Kaigaku and killed him without his conscious knowing. He also sustained many severe injuries. It was revealed that Zenitsu’s feelings of regret and melancholy kept Kaigaku from being killed immediately.
He was able to keep up with Muzan Kibutsuji the Demon King and defeat him, even though he was severely injured by the Anti-Kibutsuji Drug. However, Zenitsu’s strength was more than likely equal to that of Hashira at the end of this series.
Zenitsu has enhanced hearing. This allows him to hear danger in the smallest of sounds. He has demonstrated the ability to discern layers upon layers in sound, even in brothels. Another testament to his exceptional sound detection ability is the fact that he can reproduce any song he hears on a Shamisen or Koto after only listening to it one time.
He even manages to achieve a perfect pitch, despite not having any musical background. Zenitsu’s extraordinary hearing allows him to fight in his sleep, which is impressive considering he doesn’t have any visual aids and uses sound only to see his surroundings.
Zenitsu has an extrasensory sense of hearing that allows him to pick up sounds beyond the normal range. He can detect emotions, thoughts, and personality by simply listening to the subtle sounds they make.
He can also distinguish a human from a demonic by comparing their sounds, which allows him to assess their strength. Daki, an upper rank demon, produces a much more horrible sound than normal demons.
Incredible Speed & Reflexes
– Zenitsu can move at speeds that are beyond the human eye. He was weakest at the beginning of this series, but he showed his speed when he could easily evade several demons like the Tongue Demon or the Son Spider Demon. Later, he blitzed them. During the Mugen Train Arc he was able save Nezuko (of Lower Rank One Enmu’s) flesh appendages and cut through many of them before Enmu could respond.
His speed improves as he goes along, and Upper Rank demons like Kaigaku and Daki can’t see his movements. The former’s reflexes have been amplified multiple time during fights and the latter using the same Breathing Style that Zenitsu. Zenitsu was able to move faster than Kaigaku with his lightning Blood Demon Art, and cut his neck before the attack hit him.
Even more impressive, Zenitsu was able to land multiple hits on Muzan Kibutsuji the Demon King at an imperceptible speed using his techniques, even though he was already severely weakened.
Incredible stamina & endurance:
Zenitsu is a remarkable fighter with incredible endurance and stamina. He was able to fight even after being poisoned by the Son Spider Demon, which gradually made him weaker and turned him into a spider. He was also capable of defending 3 train cars together with Nezuko over a long period of time, without fatigue.
Zenitsu and Inosuke later engaged in combat against Upper Rank Six (Daki) for a prolonged period of time. They were both wounded by the Upper Rank, but they managed to escape without being trapped under rubble. Zenitsu still had enough stamina to use his Thunderclap and Flash; God Speed techniques against twice, one to escape the rubble and the second to blitz Daki.
Zenitsu has an indomitable willpower to defeat demons. This was demonstrated when he refused to allow Inosuke to kill Tanjiro’s demon and instead protected it until the end, despite being relentlessly attacked by Inosuke. Zenitsu fought on against Daki’s battle, even though he was unconscious.
He sustained numerous slash injuries to his body and had his feet broken.  Zenitsu’s cowardice was overcome by anger and he continued fighting against demons. This was evident in his fight with Kaigaku, Muzan and the fight with Muzan in which he refused give up and persevered despite being injured and enervated.
Master Swordsman Zenitsu is an extremely skilled swordsman. He is particularly proficient in Iaijutsu-like swordsmanship as well as the Thunderclap Flash technique. Zenitsu can even create offshoots from the technique and use them while asleep. Zenitsu’s swordsmanship skills allowed him to defend three train cars that Enmu was attacking and fend off dozens upon spiders.
Zenitsu’s sword-wielding skills improved to the point where he was able to fight the Twelve Kizuki Upper Rank demons. Later, he was able to match a severely weakened Muzan. This suggests that Zenitsu has had his sword skills improve to the point where it matches that of the Hashira.
First Form: – The user takes off their katana and sprints at blinding speed to decapitate their opponent. This technique is very similar to Iaijutsu. It is described as “lightning ripping through air” and it’s movements are very similar to Iaijutsu.
Sixfold – A Zenitsu extension of the Thunderclap and Flash techniques. While performing Thunderclap and Flash six consecutive times, the user slightly increases his speed and power with his dashes.
Eightfold- A Zenitsu extension of the Thunderclap and Flash techniques. While performing Thunderclap and Flash eight consecutive times, the user slightly increases his speed and power with his dashes.
Zenitsu’s extension of the Thunderclap and Flash techniques, Godspeed. While performing Thunderclap and Flash, the user greatly speeds up the technique. Unconscious Zenitsu commented that he shouldn’t do this technique more than twice during the first demonstration. Otherwise, his legs would become useless from muscle fatigue and exhaustion. Zenitsu showed improvement in his proficiency during the fight against Muzan Kibutsuji. He was able to use this technique more than once while maintaining its power and speed.
Seventh form: Honoikazuchi No Kami Flaming Thunder. This is Zenitsu Agatsuma’s personal creation. The user sprints forward at blinding speed and unleashes an unrelenting forward slash from a low stance. It is accompanied, it seems, by a yellow Japanese dragon that looks like a lightning bolt.
