Kusuo Saiki was born with supernatural powers. Thanks to his laid-back parents, he lived a fairly normal life. However, it turns out that having supernatural powers isn’t really all it’s cracked up to be. Although Kusuo’s parents are currently fighting each other, he tries to stay out of it since he thinks that it is a problem that they need to work out for themselves. Kusuo’s telepathic abilities allow him to read the thoughts of everyone around him. Everyone, that is, except for one particular individual... Shun Kaidou is another one of Kusuo’s classmates at PK Academy. He claims to have special powers and believes that there are dark forces at work that have evil plans for humanity. Kokomi Teruhashi is the quintessential pretty girl, leaving all the guys awestruck by her beauty and her sweet-as-honey personality. However, her attempt to bless Kusuo with her presence leads to some unexpected results.

It’s dodgeball time in Saiki’s PE class. As usual, Saiki tries to conceal his abilities, but his attempts to keep a low profile lead to unexpected difficulties. Now that Hairo is out of the game, Saiki is the Paper Team’s last hope to win. However, Saiki is more concerned with figuring out how to keep his likability neutral so that he does not attract attention. Chiyo Yumehara, one of Saiki’s classmates, has a crush on him. In order to get to know him better, she comes up with some plans to get closer to him. Now that Saiki’s parents have reconciled, they want to sleep in the same bedroom. In order to do so, they need to move some furniture around and want Kusuo’s help. Have you ever wondered why none of the other students have called attention to Saiki’s unique looks? It all has to do with a little bit of mind control...

While Saiki is walking through the park, he comes across a magician performing a magic show. Unfortunately for the magician, it’s hard to surprise a psychic who can literally see through his illusions... Saiki likes to watch TV because he can avoid reading the minds of the people on the TV, and thus is able to experience surprise and excitement like ordinary people. He experiences one such surprise when he sees Uryoku Chouno appear on TV. Kaidou is summoned by a mysterious individual who belongs to a group trying to destroy Dark Reunion. He says that they need Kaidou’s help and tries to enlist Kaidou into the group. Saiki’s day at home is interrupted when Nendou finds his house and asks him to go with him to the beach. Due to his mom’s “persuasion,” he ends up going, but then... On the first day of the new school term, Saiki and Kaidou notice that Nendou is acting strange. Wanting to know what’s up with him, they decide to follow him after school.

Saiki receives a letter from someone claiming to know that he’s a psychic and wishing to be his apprentice. This person also claims to have special abilities of their own. Saiki hears his classmates talking about a new student in the class next to theirs. Of course, that student turns out to be Reita Toritsuka, the psychic medium that wishes to be his apprentice. After school, Hairo asks Saiki to help him finish up making the entry gate for the school’s Sports Day. However, they discover that the arch and pedestal are broken and Hairo won’t rest until it has been fixed. Saiki’s parents leave for a wedding, and now Saiki’s got the house all to himself. Noticing how messy the house is, he starts to clean up, only to discover something truly terrifying. Saiki gets worried when he notices that Chiyo Yumehara has been eyeing him again. When he learns that things aren’t going well between her and her boyfriend Takeru, he decides to help mend their relationship.

It’s four o’clock. Saiki wants to leave school right away so that he can catch a TV show. As he tries to leave school, though, he realizes that people are looking for him and now he needs to figure out how to get out of school without being noticed. Today is PK Academy’s Sports Day and of course Hairo is fired up to win it! After a failed attempt at trying to get out of attending, Saiki must now try to once again perform perfectly mediocre in order not to call attention to his abilities. After Nendou pulls out one of Saiki’s “hairclips,” Saiki suddenly collapses and falls unconscious. At that moment, around the world, strange events begin occurring. After the tug of war event, Class 3 is still behind the other classes. In order to win first place, they’ll have to earn a lot of points in the remaining two events, the beanbag toss and interclass relay. Saiki’s school is having an evacuation drill today. Students are expected to follow the instructions and evacuate the building; however, they seem more preoccupied with the mnemonic they learned instead.

Saiki is faced with a dilemma that requires careful deliberation. When it comes to coffee jello, which is more important, quantity or quality? Saiki’s classmates have been talking about the House of Fortune-Telling that recently opened up. Although Kaidou says fortune-telling is stupid, he goes to check it out. Nendou is taking Saiki and Kaidou to a ramen shop that he heard was good. On their way, they run into Teruhashi and she asks to join them. Being a psychic medium from birth, Toritsuka can see ghosts. Unfortunately, he wants to use these powers for his own guilty pleasures... Saiki wakes up and immediately realizes that his powers are gone. He rejoices now that he’s free from the curse of his psychic powers.

Are you a cat person? Or a dog person? As for Saiki, he couldn't care less. So what will he do when he encounters a cat in trouble? It’s the Christmas season. Saiki’s family is having a Christmas party at home. When he gets home, he finds a surprise guest waiting for him. It’s New Year’s Day. The Saiki family is visiting a shrine to say prayers. Saiki’s wish is to spend a quiet time at home during the New Year’s holidays. Will it be answered? Kurumi and Kuniharu get excited to see that Kusuo has so many friends, and end up inviting them over to their house for New Year’s. It seems that Kuniharu’s efforts to undo the damage of his wife’s mistake of spilling the beans about Kusuo having psychic powers didn’t work after all. Now Kusuo has to do something to rectify this situation.

Many students at Saiki’s school can’t stand Mr. Matsuzaki, their PE teacher. When he confiscates some of their things, a group of students decides to get back at him. It’s Valentine’s Day, and the guys are all anxious to see how many chocolates they’ll get. Toritsuka, who’s trying to be nice to girls for this day, asks Saiki to foresee if he’ll get any chocolates. Nendou comes by Saiki’s house to ask him to come check out a big hole he dug. Saiki evades this bad situation by pretending to be out. However, his problem isn’t quite over yet. Saiki’s mom Kurumi is so trusting that she gets easily taken in by salesmen. Today, she purchases bottled water that she’s told has mysterious powers. After coming across a ring that cancels his telepathy, Saiki decides to go someplace where he’s always wanted to go if he lost his telepathy: a movie theater.

Toru Mugami, the movie star Teruhashi was with at the theater, comes to see Saiki. He says that he wants to discuss something concerning Teruhashi. Students at PK Academy are taking final exams. Nendou is told that he’ll have to repeat Year 2 if he flunks three or more subjects, but he says he’s got a secret plan for passing his tests.

The time finally comes to perform the body-cutting trick, but can Saiki make it a success? PK Academy forbids their students from working. However, one of Saiki’s classmates, Chisato Mera, works at a café he likes to visit, and asks him not to tell anyone about it.

It’s time for the physical fitness test in Saiki’s PE class. Hairo is even more fired up than usual since he’s got a powerful rival now. When the cat Saiki previously saved starts coming to his house and meowing every day, Saiki comes up with a plan to get rid of him. Saiki does not play popular video games because he telepathically overhears spoilers. So he's decided to play “Olfana’s Story,” a crappy game that no one else is interested in playing. On their way home, Saiki, Kaidou and Nendou run into Kaidou’s mother. Seeing her son’s friends, she asks him to invite them over to their house for some tea. Toritsuka likes one of his classmates, Yoriko Itano. When Saiki refuses to help him hook up with her, Toritsuka gives it a shot on his own using his new spiritualism ability.

When Saiki sees a boy’s balloon flying away, he uses his psychic powers to jump high and get it back for him. The boy thinks that Saiki is his favorite hero, Cider-man No. 2, and starts following him. When Kuniharu is late for work, he asks Saiki to teleport him to his office. After being bribed with a coffee jello, Saiki teleports him to work. Once there, Saiki ends up going to the office with Kuniharu to check the place out. Just when Saiki thinks that he can have a quiet, relaxing day, his neighbor Yuuta stops by and wants to watch the Cider-man Blu-ray with him. There’s a festival going on, and Saiki goes to check it out. He tries to keep a low profile as usual, but his telepathy isn’t of much use to him because of the huge crowd. Teruhashi and Yumehara run into each other at a cafe and decide to sit together and talk. Then the subject of who they like comes up...
