Ken Takakura (
Takakura is a young man of average height with black hair, blue eyes, and wears round-frame glasses. When he was introduced, Takakura's hair was originally fashioned in a bowl cut but soon becomes unruly after his confrontation with the Floodwoods Monster. He wears his school uniform, which is a typical gakuran outfit.
Takakura is a firm believer of the existence of UFOs and aliens that makes him come off as an eccentric individual, having drown into a passionate rant about the aforementioned topic after wanting to confront Ayase. Before learning that ghosts exists, he was first skeptical of them since he believed that there were logical explanations as to why people would come to the conclusion of this paranormal activity. Takakura also possesses a negative view of himself and acknowledges that he comes off as being socially awkward, which causes him to struggle with making friends. Despite this, he doesn't hesitate to say what he's thinking and is shown to express a range of emotions such as anger, shock, fear, and embarrassment.
Ever since elementary school, Takakura had a hard time fitting in with the crowd and was constantly picked on by others. In an effort to make any friends, he tried contacting aliens, which eventually developed into an obsession.
While engrossed in his reading about outer space, Takakura is bullied by a few of his classmates but becomes soon finds himself being defended by Momo Ayase. After the bullies cease their activity, Takakura sees Ayase leaving but decides to catch up to her after he had noticed how she took an interest in his book. He then goes on to talk to her about outer space and the existence of UFOs but only manages to annoy her. Ayase apologizes for being rude to him and tells Takakura that she does not believe in aliens but rather in ghosts since her grandmother is a psychic. Takakura makes light of Ayase's belief after snickering and quickly gets into an argument between her. Takakura then challenges Ayase that he can prove UFOs exist by having her go to Nagi Hospital, while Ayase challenges Takakura that she can proof to him that ghosts exist by having him go an a cursed tunnel.
After arriving at the tunnel late at night, Takakura talks to Ayase on the phone and hears about the history she had with her grandmother while she roams around the hospital. Takakura then finds himself face-to-face with an elderly woman and runs away in fear while also denying what he saw was a ghost. Ayase becomes aware of the situation and warns Takakura that he can't afford to get caught by the Turbo-Granny or he will be cursed. However, as he takes off on his bike, Takakura sees the Turbo-Granny ahead of him, resulting in him being caught and cursed.
Shortly after, a cursed Takakura emerges from Ayase's phone, after she was abducted by the alien group known as the Serpo, and apologizes to her for getting caught by the Turbo-Granny. The possessed Takakura starts to go on a rampage but becomes subdued by the Serpo's psychokinesis powers. After he slightly manages to come to his senses, Takakura begs the Serpo to not harm Ayase since she was he grateful to her for the time she stood up for him. He then witnesses Ayase using psychic powers to take down the Serpo, after the alien accidently overstimulated her brain waves, and manages to have his cursed suppressed by the latter. The two then manages to escape after Ayase destroys the UFO they were in and have come to believe that both aliens and ghosts exist from what they experience just recently.
Not wanting to trouble her any further, Takakura tells Ayase that he will find a way to release himself from his curse alone. However, Ayase insists on helping him and asks for his name since he never told her earlier. He reveals his full name is "Ken Takakura", which causes Ayase to become speechless since he has the same name as her beloved idol, Ken Takakura. Refusing to address him by his name, Ayase tells Takakura that she will refer to him as "Okarun" from now on and demanded that he not speak his real name in front of her, to which he agrees to since he thought he had no other choice in the matter.
After it becomes morning, Takakura is invited to stay at Ayase's home until it becomes night again when the Turbo-Granny reappears. Initially, Takakura becomes unable to walk through the gate since the charm attached to it prevents any ghosts from entering but is allowed in after Ayase removes it. Once the two changed clothes, Takakura becomes infuriate with the fact that he lost his privates to the Turbo-Granny, only for Ayase to remind him that he was the one who started everything that happened after he came to talk to her about the supernatural. Takakura explains that he didn't want to pass up the opportunity to make friends with her since he was alone but believes that it could never happen since they are two different people. However, Ayase tells him that he was quick to make assumptions about people and would like to make friends with him. Soon after, the two hear the door ring, which Ayase believes is the presence of an evil spirit since the charm was previously removed and the fact that there are two types of doorbells for humans and ghosts in the house. Takakura and Ayase step outside to see that the area is covered in black fog that causes them to cough up blood and the torii gate is blocked by a wall, which prevents Ayase from putting the charm back. Finally, the two find themselves encountering a giant alien known as the Floodwoods Monster and run in panic from its rampaging. Using Ayase's psychic powers, Takakura partially takes control of the Turbo-Granny's speed to deal damage to the Floodwoods Monster and helps to bring the fight to an end after Ayase puts the charm back in place, causing the alien to burn to ash. Though the conflict was over, Takakura finds himself in trouble after his curse starts to take over his body and is unable to receive assistance from Ayase due to the girl having exhausted herself. Luckily, Ayase's grandmother arrives on time to stop Takakura from harming Ayase and has him locked in the shrine until he had returned to normal.
Later, Takakura returns to normal and is visited by Ayase. He then becomes relieved to know that he did not hurt her but has the door shut on him after Ayase overacted over her concern for his well-being. After being let out, Takakura is told by Ayase's grandmother that he and Ayase will have to undergo training in hopes of drawing out the Turbo Granny from its bound territory in a game of tag in order to weaken and defeat it. Thinking that she wanted to stop being his friend after his poor performance during the Floodwoods Monster's attack, Takakura apologizes to Ayase but is told by her that he was acting disillusion and did well in handling the situation. The next day, Takakura and Ayase begin their training but are cut short after the Turbo-Granny warns Ayase that it will kill everyone near Takakura if they continue, leaving them with no other choice but to travel to the tunnel tonight.
Takakura and Ayase arrive and enter the tunnel but find themselves trapped by the Turbo-Granny on both sides. After a failed attempt to attack the Turbo-Granny blocking their exit, Takakura has Ayase partially release the curse on him to fight back. However, not wanting them to use its powers against it, the Turbo-Granny releases Takakura from his curse by returning his privates. The Turbo-Granny then prepares to eat them while they are helpless but is stopped after Ayase challenges it to a game of tag, to which it accepts. Takakura tries to run away with Ayase before the ghost finishes counting for ten minutes but sees Ayase trapped after the Turbo-Granny pulls a trick on them by counting for ten minutes in a different way. Takakura becomes furious for having done this and assaults the Turbo-Granny by targeting its breasts, which leads to the ghost to taking over his body completely. However, with help from Ayase, the Turbo-Granny becomes sealed within Takakura and is returned to normal. Having defeated the Turbo-Granny, the bound spirit within the tunnel chases after Takakura and Ayase throughout Shounou City. Using the Turbo-Granny's speed, Takakura carries Ayase on his back and enters an Onseen after Ayase comes up with the idea of boiling the giant crab spirit. Though they managed to buy some time to try to escape Shounou's borders, Takakura and Ayase find themselves ambushed by the citizens of Shounou City being possessed by the Turbo-Granny and the bound spirit.
Using the Turbo-Granny's powers again, Takakura carries Ayase and dashes through the crowd but results in him using up all his strength. After accidently letting go of the Turbo-Granny within Takakura, the ghost kicks both Takakura and Ayase away and fuses with the bound spirit. While unconscious, Takakura is carried by Ayase after the girl uses her psychic powers to latch onto a moving train that was heading to Kamikoshi City and brings down the Turbo-Granny with help from Hoshiko. However, the Turbo-Granny secretly slips into Takakura's body at the last minute and accidently loses his balls. Once their problem was over, Takakura, Ayase, and Hoshiko return to the tunnel to pay respects to the spirits of the deceased girls who were revealed to have been murdered there. He then joins the two in celebration of their victory and, after it was time to say goodbye, becomes reassured that he will see Ayase again at school after she tells him that she will see him tomorrow.
The next day, Takakura happily meets up with Ayase at school and becomes eager to talk to her while in class. After class ends, Takakura tries to reunite with Ayase for lunch but finds himself unable to find her. He then thinks that she was intentionally trying to avoid him, which makes him feel depressed that he failed to make a friend. As he walks off, Takakura accidently bumps into Ayase, which causes his lips to meet with hers. The two then reassured each other that they were trying to find each other but are then faced with attention from Ayase's friends who were there to see them accidently kiss. Takakura and Ayase try to clarify that they are not in relationship but end up shooting insults at each other. Takakura then angrily walks away to the bathroom and becomes shocked that his balls are missing.
