Live Action Yamazaki Kento


Kusuo Saiki (斉木 楠雄, さいき くすお lit. Saiki Kusuo) is the main protagonist of the series who has all kinds of ESP-related abilities. He usually tries to avoid getting into troublesome situations. His trademark appearances contain his green-tinted glasses and two pink antennas located slightly above each ear, which have the function of limiting his power. In the beginning, he was always seen alone but as the story progresses he eventually gets along with his schoolmates, especially Riki and Shun. Kusuo was starred by Yamazaki Kento in the live action movie based on the series.

Appearance

Kusuo CharaFull
Kusuo wears a limiter on both sides of his head which is never removed unless it is absolutely necessary or by accident. During the days he has school, he wears the standard PK Academy uniform that all male students wear. On his days off from school, he occasionally wears clothes that are sewn by his mother.[4] However, there are times he is forced to buy clothes since his mother has an interesting taste in clothing patterns.

Kusuo's appearance is not limited to that of a male, as he can also transform into anything (but it takes 2 hours to transform.) While in his female form, Kusuo goes under the name Kuriko[5] (formerly Kusuko[6]). In this form, he has lighter pink hair, lacks visible limiters, wears glasses (although not tinted green) and usually wearing the female standard PK Academy uniform. In his cat form, Kusuo is known as Psi and has white fur. In this form, he still wears his glasses and his limiter is in the form of a collar around his neck.

Young Kusuo Appearances

As a child, depending on the time period, Kusuo does not wear any limiters nor his glasses, showing his violet colored eyes. He has striking dark pink hair, that differs from both of his parents and the rest of the world, until he used mind control.[7]

As of the finale, he no longer wears his limiters or glasses. However, right in the end of the epilogue chapters, he reprises them due to his powers begin to return.

Personality

As a psychic, Kusuo is usually emotionless and restrains himself from having any friends, preferring to do whatever it takes to not to be associated with others so that he doesn't expose his powers. Partly due to this, he has never spoken using his voice, instead preferring to project his words via telepathy into the minds of others. Although he did not have any friends the first year, during his 2nd year, a lot of his classmates like Riki, Shun, Kineshi, Aren, Kokomi, Chiyo, Reita, and Mikoto kept on bugging him and somehow changed his perspective. He later thought of himself as a friend of theirs and even outwardly called Shun his friend.

Although he doesn't express much interest in many things due to his powers (e.g. surprise parties, romance, fortune-telling, etc), Kusuo is addicted to the dessert known as coffee jelly and can be persuaded to participate in anything his friends are in as long as he receives his coffee jelly. His addiction is not just limited to coffee jelly but also to different kinds of sweets. Despite being able to get anything he wants without using any money, Kusuo uses money and saves up money to buy something he wants, like the Coffee Jelly Maker.[8] His kind mom is the sole reason why he doesn't abuse his psychic abilities for evil activities. Kusuo also has an interest in television shows, due to electronics (unless he uses his psychometry) being mostly unaffected by his powers, allowing him to enjoy dramas/scenes that prevent the use of his telepathy which leaves him open to spoilers from the thoughts of others.

History

Kusuo was born on August 16th by completely normal parents, housewife Saiki Kurumi and manga editor Saiki Kuniharu. He was raised by them along with his older brother, Saiki Kusuke.

Baby Kusuo

During his mother's pregnancy, Kusuo was using his transformation ability which can be seen in the CT scans. When he was born in the hospital, he came out as a girl but an hour later he became a boy.[9] At the age of 1 year old, Kusuo was able to fly, teleport and use telepathy to communicate with his parents. Kusuo was then pursued by an Intelligence Agency of a certain nation for his powers when he was 4. Since then Kusuo conceal his powers to avoid unnecessary trouble and erased the Intelligence Agency along with the nation.[10]

When he was 6 years old, he slowly started to befriended Akechi Touma, an observant boy who criticizes one of their classmates. They first met in their elementary school's entrance ceremony, Touma wets himself due to nervousness, and Kusuo took him to the restroom. They ended up in the same class and sitting next to each other.[11] One day, after school, Kusuo was about to teleport behind a bush, due to wanting to see a certain television show, and he witnesses his classmates bully Touma. Thinking Touma has passed out, Kusuo healed him by touching the tip of his shoe to Touma's arm.[12]

Young Kusuo Telling Touma

Kusuo telling Touma about himself

Prior to current Kusuo travelling back in time, Touma quickly wakes up and asks young Kusuo if he just healed him and if he is a psychic. Kusuo uses his "playing dumb face" while several other kids were around. The other kids leave but Touma sticks around, still amazed at what he has done. Kusuo takes a liking to him; Touma asks him to show him more and thus he tells Touma about his powers. After some events, Touma ends up telling the class he is a psychic and Kusuo ended up destroying the classroom. Kusuo then swore to himself to never reveal his powers to anyone after that.[13]

After current Kusuo traveled back in time, he influenced the event and everything changed. Young Kusuo leaves before Touma wakes up and unknowingly dropped his name tag. The next day, in PE class, Touma was bullied in front of his classmates. Right before he was about to be hit again, Kusuo uses his powers to their classmate on the pull up bar. At that moment Touma loudly exclaimed that Kusuo is a psychic but Kusuo doesn't say a word about it.

Kusuo Seeing Touma Bullied

Kusuo seeing Touma get bullied

A year after the pull up bar incident, Touma still talks to Kusuo. Kusuo always saw how their classmates bully Touma, like taking his shoes and writing mean things about him in the chalkboard. Then one day, Kusuo was walking home when he suddenly heard Touma was in trouble. He runs back to the school and finds that Touma has been knocked out by his classmates and is been made fun of. Kusuo snaps and destroyed the classroom. The next scene shows the destruction of the classroom and the bodies of injured children on the ground with Kusuo standing with a stolid face. He erases their memories of him arriving to the scene and made Touma forget about the pull up bar event. Kusuo soon transfers away, afraid that their memories will come back if he stays.[14]

Sometime closely afterwards, Kusuo started wearing his green-tinted glasses, that he found in his toy box,[15] to block his petrification ability. They are shown when he visited his maternal grandparents. He got along well with his grandparents in the trip, but did not tell them about his powers.[16]

After Kusuo Puts on Limiters

Right after Kusuo puts his limiters for the first time

When he was 11 years old, he started using his control devices[17] that he and mostly Kusuke invented.[18] They, along with their parents, initially thought it would completely remove his powers. However, the limiters instead weaken his powers, to the point of removing his petrification ability for awhile. Kusuo quickly figured out that his left limiter limits his powers but did not understand what his right one did. He soon finds out Kusuke put it as a self destruct switch, which, upon removed, his powers were to be revealed to the whole world. Kusuke made it a competition between the two, where he would try to remove it over the years and Kusuo beating him every time.[19] Eventually, a year later, Kusuke leaves to England[20] and Kusuo does not see him for several years.[21]

Kusuo and his family lived in a different area in Japan up until he was in middle school.[22] Around his first year of high school, his family moved to Hidariwakibara Town after buying a house from Kusuke and due to an accident with his powers.[23] Thus, at 15 years old, Kusuo transfers into PK Academy.

His abilities kept on increasing, which Kusuo thinks they are nothing but trouble. Kusuo had been keeping his distance from his classmates but Riki, known as their delinquent, was bullying him. Riki only became friendly with Kusuo when he implicitly helped Riki from being framed by Takahashi as the class' wallet thief.[24] After the two got friendly, Shun went to befriend Kusuo who then rejected the later's quest on finding the mysterious alien (which turns out to be Kusuo). After learning the reason why Shun insists on becoming his friend, Kusuo finally gave up and transformed into the alien that Shun was looking for.[25] The three started to hangout since then.

In Kusuo's 2nd year in PK Academy, he ends up in the same class again as Riki and Shun. There he also meets his other classmates like Kineshi, Aren, Kokomi, Chiyo, Reita and Mikoto, who kept on bugging him and somehow changed his perspective on being alone. He later thought of himself as a friend of theirs, to the point of even calling Shun his friend.[26]

When Touma transfers to PK, he became nosy about Kusuo's circumstances as he still suspects Kusuo as a psychic. When Touma confronted Kusuo about the incident at their old grade school, Kusuo was hesitant so he petrified Touma. He decides to try on changing the course of the story by going back to the past on the day before Kusuo rampaged on the grade school. He then went back to the current time he was originally in, defeated, and the petrification does undone on Touma. He then decided to again tell Touma about his powers.

These are the alternate worlds that was introduced in the series.

Censored World -Kusuo didn't enroll in PK Academy and then was thus unable to mingle and talk to the other students/characters. He then turned the world into a censored world in just 10 chapters. Instead, the other work of the author, the Mikami Case Files was serialized.[27]
Modified 2014 World -Kusuo influenced the meeting of his parents encounter which changed the flow of the events. Kusuke created a time machine which was the cause for the World War 3 to break out and the world met it's destruction. The cause of Kusuo's death was unclear but in Modified 2014 World, he has been dead for more than 3 years.[28]
Unable To Save The Dog World -In Chapter 1 or Episode 1, in another world "Kusuo" wasn't able to save the dog from the incoming truck. Devastated by the accident and his hesitant attitude, "Kusuo" decided to change for the better and used his psychic powers as people came to ask for his help.[29]
