Kairi also wears a round maroon necklace with a yellow triangular talisman.

## Personality

Kairi has a very strict and no-nonsense personality. He despises incompetence and laziness, and would constantly scold who isn't trying hard enough. Kairi himself, although a prodigy, also trained incredibly hard to get to where he is now. He can develop a sense of arrogance or superiority to him, looking down onto lower ranks and calling them "peasants".

Worse, he hated demons even more. He sees them as sodden dirt and unsanitary, wishing to remove them to spare his eyes from their disgusting nature. He hates it when others sully his outfit and prefers to stay clean. He is described as grumpy or pissy most of the time, and often has a disgusted expression about him. He expects highly of everyone and expects highly of himself.

Unfortunately, his attitude isolated him from a lot of people. He didn't have a close family when he was young, living him to mostly take care of himself although being born to a rich family. Thus, he takes advantage of what he got, and expects others to do the same.

## Abilities & Attributes

### Immense Demon Detection

Kairi possesses an extremely uncanny and immense amount of demon detection. Although he may not be able to detect upcoming humans, he can detect demons incredibly well and beyond that of many Hashiras. Kairi can sense demons even of the Upper Moons, including Kokushibou and Muzan. Although this does not contribute to his actual fighting skills, detection can help him avoid surprise attacks and the directions of said demons.

Kairi describes this trait as a flowing stream. Demons are unnatural, and act as obstacles to that streams. He himself can sense sudden obstructions to the natural flow of things, and thus could determine the presence of demons.

### Immense Stamina & Endurance

Kairi arguably possesses the endurance to that of an average Hashira. During the Infinity Castle arc, he was able to fight constantly while protecting other Slayers. He was moving around, backing up different groups and killing large swarms of demons for many hours without collapsing. But his speed wasn't any close to that of a Hashira, so he was almost swarmed and killed if not for Takeshi's and Yoshino's intervention.

### Great Agility

Through weilding the fans, Kairi was able to mimic the serene and smooth flow of water. He became very agile, performing techniques in impressive flowing manner. He was able to impress Upper Moon 4 with how flexible and agile his fighting skills are, reflecting the beauty of water flowing.

### Adaptive Abilities

Kairi is a very fast learning, earning him the the title of child prodigy. Kairi rose up the ranks incredibly quickly, deeming him a prodigy. Though not skilled enough to become Hashira, he could use Total Concentration Breathing and rose to Kinoto within one year after the Final Selection. During the Mount Natagumo arc, Kairi was rank Tsuchinoto. Kairi adapts very well to fighting alongside other Breathing styles, as well as adapting in fights. He was also able to fight alongside the Bird Hashira and Yoshino, able to cooperate with their Breathing Styles with ease.

## Relationships

### Takeshi Kajiwara

Kairi sees Takeshi as a strange individual. Takeshi is very patient and appears as reserved at first, but rambles a lot. Takeshi's rambles annoys Kairi, but Kairi doesn't stop him because he is a respected Hashira. Kairi doesn't like to be around Takeshi because he constantly irritates Kairi's demon detector. Kairi first met Takeshi on a mission in Mount Natagumo.

Kairi was fighting several demon puppets and a spider demon until Takeshi intervened. Kairi was able to sense Takeshi's demonic nature but couldn't react fast enough for his arrival. But he was surprised when Takeshi took out the demons instead of him. Kairi was later tied up by Takeshi, but he asked the former Hashira why he killed the demons when Takeshi was demon himself. Takeshi was impressed by Kairi's abilities to sense his demonic aura, especially when Takeshi has put a lot of effort into concealing it. Later, during the Infinity Castle arc, Kairi was battling a swarm of demons when he sensed Takeshi's familliar aura arriving to back him up. The two cooperated to back up the other Slayers afterwards.

### Tanjiro Kamado

Kairi first meets Tanjiro after the Final Selection. He commented on how Tanjiro and Genya were arguing over stupid things, and that they get on with it so Kairi could get his sword. Kairi doesn't seem to like Tanjiro, but this came from a deep jealousy that Tanjiro wasn't alone like Kairi was. Eventually, Kairi became pen pals with Tanjiro, sometimes writing him letters.
