Kaiyō Tameyama

**Kaiyō Tameyama** (為山 海瑶 (ためやま かいよう), *Tameyama Kaiyou*?) is a major supporting character in the *Jujutsu Kaisen* series. He is a first-year student at Tokyo Jujutsu High, studying alongside Yuji Itadori, Megumi Fushiguro, and Nobara Kugisaki. Due to the instability of his Cursed Technique, Kaiyō temporarily holds the rank of Special Grade, despite being a Grade 2 jujutsu sorcerer.

## Appearance

Kaiyō is a relatively tall, though lean, teenager. Most of his peers describe him as "sickly-looking" due to his pallid complexion and fatigued expressions, but he possesses quite a fit figure underneath his loose clothing. He has disheveled, taupe-colored hair with bangs that frame his face. Kaiyō has upturned and half-lidded, ebony-hued eyes, accompanied by thin eyebrows.

His Jujutsu High uniform is incredibly customized, appearing vastly more casual than the traditional one. Kaiyō wears a long, black undershirt beneath an oversized and creased button-up, leaving the two topmost buttons undone. He also wears dark, knee-torn skinny jeans with cuffs folded at the ankles, low-top sneakers, and white socks. Above his clothes, Kaiyō usually sports a pair of wired earbuds linked to a digital Walkman and a thigh-holster for his *kaiken*.

During the winter, he replaces his button-up with a black and white striped hoodie.

## Personality

While Kaiyō's outward disposition is that of a friendly but assertive teenager, his inner characterization lies far away from that impression. Kaiyō is defined by his contempt towards himself — as a result, he puts on a front to deter others from prying.

Although Kaiyō doesn't think he deserves goodwill, it does not mean he's unkind to those around him. He maintains good relations with the other students of Tokyo Jujutsu High, frequently hanging out and running errands for them. Despite his attitude, Kaiyō can become highly competitive over the slightest things. In this state, he's incredibly emotional and prone to throwing insults.

Kaiyō's life within the jujutsu world has sparked many of these feelings, as his Cursed Technique has remained the subject of much tension, even after implementing a Binding Vow to control it. He was treated as a calamity, causing Kaiyō to believe himself to be sub-human. As a child, he was reserved and prone to anxiety, shutting down whenever he interacted with others. It was only due to meeting Satoru Gojo and Megumi Fushiguro that Kaiyō began to stop acting so outwardly nervous.

Despite disliking jujutsu, he won't let that interfere with matters concerning others. After learning of Mahito from Yuji Itadori, Kaiyō was overcome with rage at the Cursed Spirit's nonchalance towards human life. This is later highlighted during the Shibuya Incident, where he maims a Curse User chasing after civilians.

After Satoru Gojo's sealing at the hands of Kenjaku, Kaiyō begins to discard his self-hating mentality and embrace his "monstrous" Technique. He no longer puts on an act around his peers, instead becoming brutally honest and detached.
