Yuta Aoi

The younger twin of the two, Yuta is far calmer compared to his high-energy brother. However, despite his sunny and sociable disposition, he does still become insecure at times as he grows up. Cherishes Hinata, his older brother, greatly. With a tender, lively singing voice, his performances are out of the ordinary and without restraint.

Yuta is of average height and build, and can often be seen with more serious expressions than his twin Hinata. He has medium length orange hair that is parted in the middle, with two aqua clips on the right side. His eyes are green. He wears the school's uniform with the collar up and his shirt untucked. He can also be seen usually wearing aqua colored headphones with the cord tucked into the pocket of his blazer, which is left unbuttoned. The headphones have a small black and white circle design on them. He also wears dull blue sneakers with red accents and white laces.

On stage, Yuta wears a teal jacket with pink insides, opposite to Hinata. The color scheme is their unit's signature colors--hot pink and aqua blue, and accented with white, black and yellow. There are pink straps connected to his jacket that flow around. Underneath the jacket is a white, high-collared vest with a black accents and a zipper down the middle. He wears a belt with a teal strap and white-pink triangle buckle. Yuta also wears black pants with a yellow stripe down the sides. He wears black hiker-like boots with teal, white and yellow accents. Connected to the top part of the boot are two pink triangles intertwined together, hanging from the top. Both Yuta and Hinata wear a yellow band on their wrist, and matching black headphones with a crystal-like design for the speaker. Yuta wears pink and aqua nail polish when performing.

A calm, introverted boy at first glance, Yuta tends to appear much more responsible and serious compared to his twin brother. He is still learning who he truly is, and yearns for independence: he dedicates time to discovering his tastes and exploring new sides of himself, through fashion, hobbies or otherwise.

He can be quite prideful and competitive, and does not enjoy being looked down upon or coddled. In the same vein, he likes spoiling and taking care of his friends, as shown with Shinobu or Hajime. He is particularly good at handling eccentric people and can keep his cool through chaotic situations.

Yuta has a playful and mischievous side to him; he can be quite sharp-tongued and enjoys sarcasm, and is not below pulling pranks on his seniors, including Rinne and COS PRO’s Vice-President Ibara.

While he tends not to voice his negative feelings, he can hold grudges for a long time; this results in him acting petty towards those who wronged him.

He has a self-preserving attitude, and will sabotage others if it means protecting the people he cares about.

It's likely that Hinata was born first and Yuta came after him, but there is no confirmation of this. However, ever since Hinata heard about this from his mother, he has taken on the role of being the older brother for Yuta.

Yuta holds a very strong grudge against his father, refusing to forgive him for how he treated the two of them during their childhood.

The twins' mother is described as a kind and loving woman. According to Hinata, she would've wanted the family to get along. She passed away when the twins were still children.

The twins' father is described as having been "loveless" and "not really 'decent'" in the past, following the death of his wife.

He appears to have vented his grief out on the twins, calling them "monsters" and expressing repulsion towards them due to being unable to tell them apart. This deeply influenced Hinata and Yuta's relationship with each other and with themselves, and caused Yuta to feel extremely hostile towards him.

Recently, he has attempted to show a more supportive side. He expresses genuine concern for the twins whenever they are involved in scandals, and seems to be checking up on them and congratulating them on their successes. He keeps contact with Hinata and has been attending the twins' performances as a guest.

At the moment, the twins treat him as a stranger, for better or worse. This is due to Hinata's wish to not become like him by treating people like they are less than human.

The twins are the owners of two pet cats. The cats are currently living with the twins' father at their house.

According to Hinata, the cats are "tough like them" and are fairly independent, to the point they could survive on their own (much like the twins). Yuta remarks that their cats are "not that wild," but they would have no trouble finding and eating the food at home.

Older brother of the twin brothers. He's mischievous and acts fast. He has a bright and mischievous personality, tends to run ahead, and thinks fondly of his younger brother Yuta. With a warm and lively singing voice, his performance is irregular and free. (LEADER OF 2WINK) Yuta calls him Aniki or Hinata

Hinata is of average height and build, and can be seen smiling more often than his twin Yuta. He has medium length orange hair that is parted in the middle, with two dark pink clips on his left side. His eyes are green. He wears the school's uniform with the collar up and his shirt untucked. He can also be seen usually wearing hot pink headphones with the cord tucked into the pocket of his blazer, which is left unbuttoned. The headphones have a small black and white circle design on them. He also wears dull blue sneakers with red accents and white laces.

Friendly and amiable to everyone, Hinata tends to be more active and mischievous than his younger twin brother, Yuta. He sometimes deliberately plays the "bad twin".

Despite his cheerful nature, Hinata has a tendency to keep his thoughts and efforts for their shared responsibilities hidden from Yuta. He takes on jobs without Yuta's knowledge and earns money for both of them.

Although he often appears to boss his brother around, deep down, Hinata always prioritizes Yuta and unconsciously puts him first. Initially, he was friendly towards everyone, but he started creating a barrier between himself, Yuta, and others. He would insist that they were a unified entity, and that others couldn't fully understand their bond. He often acts more like an overly protective mother than just a close twin, shown saying things like "I am both Yuta's father and mother" and "Yuta is an incredibly adorable baby."

Yuta's favorite color is aqua blue while Hinata's pink. They also use them in his outfit so that they can get distinguished, like where is Yuta and where is Hinata
