Aren Kuboyasu.

His name is an anagram of the Japanese transcription of the English word "clairvoyance" (クレアボヤンス, kureaboyansu).
Because Toritsuka Reita ended up in Class 2, he is the first transfer student from PK Academy to end up in Class 3.
He's good at cooking, drawing, and knows a lot about motorcycles.
Aside from his family, Shun Kaidou is the only person who calls him by his first name.
After reading "Kumiko's" love letter, he came up with baby names inspired by the aquamarine gemstone: a son named Akua and a daughter named Marin. Their father belonged to a motorcycle gang and their mother to an all-female gang. [1]
His aura is sharp and jagged, with a mullet hairstyle in the back. [ 2 ]
Aren currently lives in his father's childhood home. [3] The house's appearance is a reference to that of Baki Hanma, the protagonist of the Grappler Baki series.
He shares the same hairstyle, eye color, and blood type as Saiki Kumagoro.

Fighting Intuition: As a former delinquent, Aren is a strong and highly skilled fighter. In third grade, he managed to defeat all the other students and became their leader. Among the many delinquents from his old school, he is considered the strongest, and many delinquents fear and respect his strength. Even after leaving his life of crime behind, Aren retains his fighting skills, capable of defeating large numbers of people with just a few blows, and most of his opponents lose consciousness after receiving his punches. At PK Academy, several students have challenged him to duels, and he has won every single one.
Enhanced strength: Aren is physically stronger than the average person.
Heightened Senses: As a result of his life of crime, Aren developed great intuition and senses that allow him to sense when someone is following him and hiding nearby. His instincts are so advanced that even Kusuo, a powerful psychic, is amazed by Aren's ability, correctly perceiving him on two occasions: the second time he followed him to a park, and if it hadn't been for Kusuo's use of invisibility, Aren would have discovered him.

Like a typical delinquent, besides being strong and prone to getting into fights, Aren is easily angered when someone disrespects him. He struggled to control his temper when he first arrived at PK Academy. He also has a habit of grabbing anything within reach and throwing it at the person he's angry with (he nearly killed Takahashi just because their shoulders brushed). Sometimes, Aren makes a wicked, devilish face when he's angry with or opposes someone, which frightens others. However, he acts naive and childlike when motorcycles are involved. He's willing to help those who want to get their driver's license and accompanies Shun and Kusuo to their exam. At first, Aren feels uncomfortable in other people's homes. Over time, he becomes calmer and more composed when talking to others.
Aren is also quite proud and is extremely bothered by Saiko's narcissistic behavior, as he often boasts about his wealth. Because of this, he constantly competes with him and tries his best not to be surprised by Saiko's fortune. He can be considered the most normal and sensible of Kusuo's group of friends.

He's a transfer student who quickly becomes part of Saiki's group of friends. Despite his intimidating appearance, he's actually a kind person who's always willing to help his friends whenever they need it. In the show, he's portrayed as the serious one who tries to keep his friends out of trouble, but he also has a softer side that shows in his interactions with other characters.

What makes Kuboyasu Aren unique is his tough-guy persona that masks a sensitive side. He has a bad reputation at school, thanks to his tattoos and scars that make him look like a delinquent, but he isn't. He's actually a good student who takes his studies seriously and strives to maintain a good image in front of his teachers. He's also very affectionate with his family, as shown in the episode where he helps his little brother with his homework.

Kuboyasu Aren's backstory is slowly revealed throughout the series. It's revealed that he used to be a gang member before deciding to turn his life around and focus on his studies. This aspect of his past makes him stand out from other characters in the show, as it shows that he's not just what he seems. It also adds depth to his character, making him more interesting to watch.

Overall, Kuboyasu Aren is a great addition to the cast of "The Disastrous Life of Saiki K." His tough exterior and sensitive personality make him a unique character with whom viewers can easily empathize. He's an excellent example of how appearances can be deceiving and that everyone has a story to tell that makes them who they are.

Appearance
Complete design of the Kuboyasu Aren
At his previous school, Aren dressed in typical delinquent attire. He sported a very long mullet and a modified school uniform with pants that resembled an oversized skirt. After transferring to PK Academy, Aren changed his appearance to look more like a normal student: he wore fake glasses, kept his natural dark purple hair color, and cut it shorter. At school, he wears the standard PK Academy male student uniform. According to Touma Akechi, Aren's uniform is too neat. On his days off, he wears long sleeves, possibly to conceal his scars, which Shun first noticed. He is very stocky and muscular.
