Arata Kaizaki (海崎 新太 Kaizaki Arata) is the protagonist of the story and a 27-year old jobless man. He has been unable to get employed anywhere since qutting his first company after only three months. His hopeless lifestyle takes a turn when he is invited to become the second test subject of the ReLIFE program under the watchful eye of Ryō Yoake to change his life for the better. With the help of a mysterious pill, his appearance is reverted to a 17-year old and he must now attend high school as a transfer student for one year. Throughout his life at the high school, he forms unforgettable bonds, learns to cope with his past and develops as a person.

Appearance Edit

Kaizaki is a fairly tall man with broad shoulders. He has short, slightly spiky and messy dark blue/black hair with bangs framing his face, and aqua-blue eyes.

In his ReLIFE appearance, his height remained the same, but his frame seemed to have gone away and his face took on much more of an adolescent look. His hair became shorter and his eyes remained the same, although less sharp. Only his appearance changes but not his body.

Personality Edit

It is stated that even though he may seem and speak selfishly sometimes, Kaizaki is strongly kind and likes the act of helping and caring for everyone. Although he himself says that he prefers to stay in the shadows, he began interacting a lot with his surroundings and classmates after he became a teen, and helps them solve their problems. He is therefore said to be very mature, supportive and responsible (like an adult) but he can also be confronting depending on the situation. He always acts calmly and takes everything nicely and is understanding, but if something really bothers him, he will react in a straightforward, angry manner.

He has great social skills and easily makes friends. Even though he has a great and friendly personality as seen by many, this side of his is overshadowed by his adult, "neet" personality. Kaizaki didn't have much self-confidence and often wondered why his life had gotten to such a low point. But after becoming a teenager, experiencing youth again, Kaizaki changes and starts doing things he wouldn't before. This will also have a positive impact once he goes back to his original form. He has a strong sense of justice and honesty, which is one of his strongest points, but is also a major flaw that can be used against him.

He describes himself as persevering - someone who would stick to something until the end, once he has made up his mind. He likes to tease his friends, especially Kazuomi Ōga, in which he can sound like an old man according to the latter. He is highly supportive of his friends and helps them out in their relationships, and although he sees them as kids ten years younger than him, he cherishes and respects all of them greatly. Kaizaki sometimes wishes that he could grow up with his friends and talk about their high school lives once they became adults.

History Edit

Childhood Edit

Kaizaki in high school.

Arata Kaizaki was born in the countryside. He grew up and lived there with his family his whole childhood. When he was in high school, he went on a class trip to Tokyo and since that moment, Kaizaki swore to move to Tokyo and go to university there. He was strongly fascinated by the "modern" Tokyo which contrasted with his life in the countryside. He also had his life planned out from the beginning. He planned to graduate, get a job, get married at 25 and start a family. None of this things came true, sadly.

Pre-ReLIFE Edit

He used to work in a Black company that did a Flower Business under the leadership of his senpai, Michiru Saiki, whom Kaizaki grew very close to. He was disappointed at the way the people in the company did their work wrongly and the way they blamed it on Michiru. Although she insisted she was fine, Kaizaki couldn't continue watching her get harassed by their male co-workers and tried to fight for her sake, which did not work as well as he planned. In the end, his senior committed suicide, an event which traumatized Kaizaki deeply. Afterwards, he tried to justify her death and was baffled by the fact that the company was fairly ignorant to this matter. Kaizaki then subsequently quit his job out of disgust of the company, revealing that he would rather be jobless than working there. The president of the company also fired him and ordered him to never come back, three months after his employment.

The event became a black stain in his life, and since then, he became jobless and began working part-time at a convenience store. His senior's death, along with the small amount of money he earned in which he had to lie to his "friends" about having a steady job, made Kaizaki stop believing in himself. He was unable to be employed in other companies because of this past of quitting a company after three months. Kaizaki eventually turned into a NEET; his mother covered his living expenses until he was laid off.

Sometime between that time, Kaizaki was scouted by An Onoya who chose him for the ReLIFE Project. When Kaizaki got to the lowest point in his life, he met Ryō who offered him to take part of the ReLIFE experiment to change his life for the better. After hearing they would cover his expenses and even get him a job after the experiment, Kaizaki accepted the offer.

Story Edit

Arata is 27-year-old man, unemployed and forced to work odd jobs in order to get by due to his parents cutting him off. His life is changed when he met Ryō Yoake and was offered the chance to better his life. Yoake presented Arata with a card that read ReLIFE which is an organization that helps people like him. He tells Arata that he would put through an experiment that'll last a year and if he performs well he might be offered a job at the organization. Excited, Arata takes up the opportunity as Yoake gives him a pill that would make him look like a 17-year-old.

Relationships Edit

Michiru Saiki Edit

Kaizaki's superior at his previous job. She was a victim of constant harassment by her colleagues, something that really bothered him.When Kaizaki tried to help her, the attacks became even worse and Saiki committed suicide. Arata blamed himself for her death and lost faith in society and in his own worth, leading to the events depicted in the story.

Chizuru Hishiro Edit

Kaizaki becomes her first friend. He thinks she's cute and is impressed she's trying her best to overcome difficulties in her life, unlike him. She initially gave him a little sister vibe, but in the recent chapters he's realized that he's in love with her. However, he's unwilling to act, as he sees that playing around with the feelings of a young girl is unhealthy, as the memories will be erased at the end of a year. Kaizaki believes that is a very cruel and unethical thing to do. Currently, he supports her as they go through the year keeping his feelings intact. In chapter 197, he said "I love you Hishiro-san, I am completely in love with you".

Rena Kariu Edit

She lends him a pencil on his first day of school. He goes out of his way to help mend her relationship with Honoka and improve the relationship between her and Hishiro. He also was responsible for Ohga realizing his feelings for Kariu. Kariu became more friendly with him on the course of the series although she still insults him due to his exam retakes

Kazuomi Ōga Edit

Ōga was one of the few students to first interact with Kaizaki. Ōga helps Kaizaki prepare for his makeup tests after he fails them. Kaizaki is disappointed at the fact that Ōga is dense even though he is so handsome. Kaizaki makes him realize his love for Kariu and is responsible for him confessing to her. After getting together with Kariu, Ōga had a difficult time deciding universities which led him to consider enrolling to a university outside Aoba which led to more misunderstanding to Kariu as he did not speak with her about his plans, there is also a tension within his home which sprouted from his parents' separation and his brother becoming a shut-in and a NEET. Ōga was able to recover his relationships with both Kariu and his brother and deciding to enter Aoba University instead of an outside university from the advice given by both Kaizaki and Hishiro who came to his rescue.

An Onoya Edit

Initially, Onoya introduced herself as a fellow transfer student to Kaizaki. Not only was she seated near Kaizaki, she also failed all her tests, so she and Kaizaki formed a study group with Oga as the tutor, and the three generally eat lunch together. She and Kaizaki often chat on the side, with Oga's (lack of) relationship status a much recurred topic.

After she was exposed as a ReLIFE employee in training, their relationship at school did not noticeably change much. The main notable difference is that now Kaizaki expects being under the surveillance of both Ryō Yoake and her, and sometimes she would send LIME messages to tease him, especially when he's alone with Chizuru Hishiro.

Trivia Edit


  • "There is no right answer for getting along. Different people require different answers."
  • "Well, you don't have to rush things. You'll make friends in time. I'm sure."
  • "Trying to knock others down a peg means lowering yourself. Don't go trampling all the hardwork and trust you've built up. It insults the effort you put in. The only way that would make you happy is if you were a loser who'd giving up on trying."
  • "Please, let that iron guard down for a minute. It's only hurting you. I know when you"ve hit rock bottom, people trying to cheer you up can be really annoying. "What would you know?""Just leave me alone." But what if someone you're pushing away is really worried about you? That'd be a shame.
  • “Thanks for thinking of me that way. That alone… makes me think this ReLife was worth living. Though you’ll forget me…”
  • (About his feelings for Hishiro)"At that moment when I let her go, I wanted to keep holding her and listen to what she was going to say. Why? Why does she have to be a high school student? If only we could have met under different circumstances. If only we can be together from now on. If only she didn't have to forget me---"
