Kineshi Hairo (灰呂 杵志, はいろ きねし lit. Hairo Kineshi) is Kusuo's classmate and the class representative of class 2-∭. Due to his kindness and leadership, he's well-trusted by his classmates. Kineshi is one of the main characters of the series and was starred by Kasahara Hideyuki in the live action of the series.


Hairo Kineshi Full Design
Kineshi sports spiky maroon hair, weird eyebrows and usually has a band-aid on top of his nose. He usually rolls up the sleeves of uniform as he mostly does exercise on school corridors.


Kineshi can pretty much be defined by three characteristics: being hot-blooded and energetic, his obsession with tennis, and having his pants always falling down. He is very reliable and is always looking after others or trying to do the right thing. There are times he gets too fired up but in the end, he’s still nice to everyone, even to Kusuo’s little group of outcast friends. He loves all sorts of sports even if it for children such as dodge ball.

Kineshi is one of the more normal, reasonable characters in the manga, although he still has a few areas where he lacks common sense like not being able to/failing to cook. Even though he’s weird and fired up all the time, Kineshi is still really popular with all the other kids in his class. Kineshi was once thought to be gay by Aren and Shun,[2] although it's more likely that he doesn't have any thoughts about love.

His enthusiasm is also his greatest weakness and causes him to do unnecessary work. On one occasion, he damaged a shutter during a fire drill, which could have been avoided if he had listened to the announcements and on another, he nearly caused the school to burn down by getting too many gas canisters. In one part of the manga, Hairo's hot-blooded personality becomes a problem during a snowball fight, since his body temperature is so high that he melts the snow around him.


Athletic Strength: Kineshi has incredible strength and stamina, but not nearly as much as Riki.

Heat Generation: Kineshi has the ability to generate heat by working out. It is hot enough to melt snow in seconds and warm up an entire classroom. It is never explained how he can do this.


Kineshi hangs out with Kusuo and his friends occasionally, but not as frequently as Riki, Shun, or Aren. At some point, he starts to one-sidedly consider Riki as his rival, thus constantly challenging him to all sorts of sporty challenges (Although Riki usually wins).

He recruits Kusuo and Riki for his tennis camp.


  • (to his classmates) "Let's do it! Give it everything we've got! Acting like kids is fine!! Let's regain the innocence of youth!! Come, let's seat it out together!!
  • (to Riki) "Nendou Riki, I've fallen for your principles in life."
  • (to a classmate) "Why are you giving up! You can do it. Cold is just a matter of mind!"
  • (New Years wish) "A formidable rival is also like a good friend. I hope I'll find someone like that."


  • His name, Hairo Kineshi, is a pun on the word Pyrokinesis (パイロキネシス lit. Pairokineshisu).
  • Furigana of his name is written in katakana instead of hiragana.[3]
  • His guardian spirit is a highly enthusiastic tennis player.
  • His favorite sport is tennis.
  • He is so enthusiastic that he frequently inspires his classmates to become enthusiastic as well.
  • His willpower apparently allows him to melt snow.
  • He is unfazed by Kokomi's looks.
  • While brash and slightly unrealistic, he is not a complete idiot, as he managed to rank 6th in the exams.
