Hairo’s Role in The Disastrous Life of Saiki K.
Comic Relief with a Fiery Twist
In a show full of strange personalities psychics, narcissists, delinquents, and oddballs Hairo still manages to be one of the most exaggerated characters. His fiery youth mentality is often the punchline of episodes where a simple task turns into an intense training montage under his direction. He takes everything seriously, which is funny in itself because the tasks are often mundane or trivial.
For example, when the class has to clean the room, Hairo approaches it like a life-or-death mission. His enthusiasm forces everyone to work harder, not because they care about the task, but because they’re overwhelmed by his pressure. Saiki, being the only one who can’t say no or escape due to social expectations, ends up dragged into these high-effort situations.
Friendship with Saiki and the Group
Hairo is part of the main friend group surrounding Saiki, which includes Kaidou, Nendou, Kuboyasu, and Teruhashi. Despite their contrasting personalities, they form a tightly-knit, if chaotic, circle of classmates. Hairo’s interactions with each of them offer different kinds of humor:
- WithSaiki, Hairo often misinterprets Saiki’s silence as deep wisdom or shared passion, not realizing Saiki is mentally exhausted by his energy.
- WithNendou, he finds a surprising equal in terms of brawn and simple-mindedness, leading to hilarious misunderstandings.
- WithKaidou, Hairo tries to nurture his self-confidence but is confused by his chuunibyou behavior.
- WithKuboyasu, their shared sense of justice sometimes overlaps, though Kuboyasu’s past as a delinquent sometimes worries Hairo.
The Idealist of the Group
Hairo’s constant desire to do what is right makes him the moral compass of the friend group, even if his sense of justice is overly dramatic. He frequently tries to push others to better themselves, whether it’s physically, mentally, or morally. This makes him a natural leader, even if his leadership comes with a lot of shouting and motivational speeches.
Episodes Where Hairo Shines
School Sports Events
Any time the school hosts a sports-related event, Hairo’s time to shine arrives. He takes the preparation and execution of these events more seriously than anyone else.

Classroom Activities and Cultural Festivals
During cultural festivals, Hairo’s intensity reaches its peak. Whether the class is putting together a haunted house or running a food booth, Hairo treats the event like a national competition. His passion often pushes the class to overachieve but it also exhausts them in the process.
Fired Up Catchphrase Moments

This catchphrase is almost always followed by some over-the-top action or decision, like trying to train harder, lead better, or demand more effort from his classmates. His intense expressions and burning eyes are drawn in dramatic fashion, which exaggerates the gag even more.
Symbolism Behind Hairo’s Character
