The happiest man in the world, who was born with everything, you say? Don't make me laugh. I'm the unhappiest man in the world, who has taken everything from me
~ Saiki kusuo


Saiki Kusuo is the protagonist of Saiki Kusuo no Psi-nan(斉木楠雄のΨ難 Saiki Kusuo no Sainan, lit. "The Disaster of Psi Kusuo Saiki") who has all-kinds of ESP-related abilities.

One day in PE class, Touma was mocking the bully in front of his classmates when he was about to be hit again but Kusuo used his powers to their classmate. At that moment Touma loudly exclaimed that Kusuo is an Esper but Kusuo didn't say a word about it. When he turned 15 years old, his abilities increased and was able to use telekinesis, X-Ray vision, and many more ESP related powers, which he thinks are nothing but trouble. His power to control his appearance has not yet been developed as people can see the antennae on his head.

Notable Feats:

Notable Attacks/Techniques:

  • Reality Warping: He demonstrated to make colored hair a natural occurrence, made it so that all injuries in the world heal much faster than normal, made it so that buildings are build in weeks instead of month, made it so that the brain works way faster in important situations, made underwear indestructible, made it so that a person with a small body can have ridiculous strength, made it so that a person can easily become unconscious by hitting them to the back of the neck, can possibly grant superpowers to every human in the world; However, he cannot return the changes he's made to normal.
  • Invisibility: Saiki can make himself and anything he's touching invisible. It takes a full minute to activate and wears off after ten minutes, though it will be undone earlier if he's touched by anyone. Additionally, he cannot use any of his other psychic powers aside from telepathy while the invisibility is active.
  • Aura: Saiki has an aura far greater than that of a normal person. While he himself can not see it, it is great enough to completely overshadow the auras of the people around him. This goes to the extent that people with the ability to see auras will think they lost their abilities when standing close to him, since they don't realize they stand in his aura, being completely engulfed by it, but at the same time can not see the aura of anyone else, due to them being overshadowed.
  • Time Leap: Saiki can time travel into the past. However, if he does he needs to go back at least 5 years. When he time travels and someone realizes that two versions of him exist at the same time he will be forced back to the present. When he arrives back in the present after time travelling his memories are automatically updated with what happened in the new version of the past. When he returns to the present however long he has spend in the past will have passed in the present as well. His time travel might activate itself randomly, getting him stuck in a time loop, instead of the normal travel, and the only way to get time to go back to normal is for him to completely empty his mind of all thoughts.
