As a second-year, Noa is the oldest member of NijiAM, and therefore the leader. He acts both aloof and somewhat stoic, but at the same time, tries to be an older brother figure for his unit to rely on.His voice is rather low for his age with a distinct huskiness to it, his performances are cool and dynamic.PersonalityNoa is typically very aloof, and detached; He said it's because it takes him a lot of effort to emote properly. According to himself, he's constantly running on "power saving mode". But even though he struggles with showing it, Noa really cares about those around him. Especially the members of NijiAM, to whom he tries to be a good senior, and in a way, an older brother figure, since he had wished he had senpais like that when he was still a first-year, and due to him also having wished to have siblings as a child.He declared himself as the unit leader, since he is the oldest idol in the group, but also because he deemed himself to be the only one competent enough to deal with that. Not because of anything with the others (although they all unianimously agreed they aren't fit to be leaders), it's because Noa suffers from fear of losing control. If he's not in charge, he can't help but fret about what might go wrong.His social battery is easily drained, so despite wishing to spend more time with his friends, Noa tends to have to retreat to recharge with some alone time. When he doesn't, he often falls asleep during the event, if he's comfortable enough around the people. If not, he'll push himself past his limit, being used to pulling all-nighters and overworking himself.BackstoryNoa is an only child that lives with his single father, after his mother was deemed unfit to raise a child when they divorced when he was 7. His father, being a single dad, is rather overwhelmed, and though he loves his son deeply, his job requires him to spend a lot of time at work.His father doesn't have much time to spend with his son, and he tries to make it up by spending money to buy his son anything he wants, mainly things like video games. Having no other family members, Noa was normally alone at home unless he had friends over, so he passed the time alone with video games as well as other hobbies like table tennis.Due to often being away, Noa and his father not only lack physically proximity, but also emotional closeness. Although they have a generally good relationship, they almost feel like strangers sometimes. Nonetheless, Noa doesn't hold any ill will towards his father, and appreciates his efforts.Trivia- His name can be romanized as either Noa or Noah. Usually, it defaults to Noa, but both ways of spelling it aren't wrong.
- His last name consists of 中 meaning in/inside/middle/center and 島 meaning island.
- As his first name is written in Katakana, it has no meaning in Japanese. Though in the west, the name Noah can mean rest.

An idol that doesn't act his age at all. Tatsuo considers basically everyone his friend and loves pulling pranks on them. Although he can come off as self-centered, he he has his own way of showing how deeply he cares about his friends and will stop at nothing to help them.With his energetic singing voice that sounds rather childlike and nasally, he seems to jump across the stage like a playground.PersonalityTatsuo is a rather childish young boy, he enjoys pulling harmless pranks and causing other small mischiefs. Known as the class clown in school, he's very outgoing and can rarely be seen alone since he easily gets bored on his own.Though sometimes his carefree nature can come off as very insensitive. He struggles to perceive his surroundings properly, and rarely seems serious about anything, rather making silly jokes and seeing things as games than an important issue. Even if he doesn't mean to be insensitive like that, much like a child, he can't easily see the world through other people's eyes and fails to see when sometimes his behavoir causes more harm than good.He has a huge admiration towards his seniors, normally giving them nicknames and ending them in "-niichan". Although he rarely ever uses formal speech for them, he shows his deep respect for them in other ways, more practical ones like being of service to them, or straight up telling them how much he looks up to them.BackstoryTatsuo has a younger sister, who is now in elementary school age, and two parents who are rather emotionally neglectful of their children, especially his sister. While they provide them with food, clothes and everything else they need, they barely got them toys, never played with them or did simple things like taking them to a park.This hadn't been all too much of an issue to Tatsuo growing up, as he had lots of friends at school to have fun with. Though unlike him, his sister was an outcast in both kindergarten, and later school, so she didn't have anyone to spend time with outside of home, and inside, she didn't have anything fun to do either. Caring deeply for his sister, he tries to keep her entertained and happy, playing with her all day instead of doing his homework. Though, with his childish mind, he's more of a playmate than an parental, older brother figure. This leads him to admire his upperclassmen, who he affectionally calls "nii-chan", trying to learn to be like them - a reliable older brother figure.Now that Tatsuo attends Yumenosaki and lives in the dorms, he barely gets to see his family. Tatsuo feels rather bad because of it, and his sister is sad about being seperated, but also extremely happy to see her brother becoming an idol.Trivia- Tatsuo's last name consists of 塩 meaning salt and 田 meaning rice field or rice paddy
- His first name roughly translates to male dragon.

Haru has a very friendly and sociable personality and will try to talk to anyone: Including tons of inanimate objects, which he treasures as deeply as any other friend. But don't get taken aback by these habits; Haru is an incredibly sweet and kind soul.He sings with a very soft, sweet and childish voice, bringing a nice and pleasant atmosphere to their performances.PersonalityThroughout his life, Haru has often been referred to as "weird". He is a very happy and bubbly individual, and talks to plants and animals, treating them as his friends. He is just as loving with humans, acting very sweet, warm-hearted and loving. Once he meets someone, he considers them a friend and loves to give nicknames. Though Haru is also very naive and struggles to pick up on social cues. Due to being considered "weird", he's struggled with making real friends his entire life and ends up being lonely. But when he meets the right people who love and accept him for who he is, he's brighter than the sun.BackstoryHaru grew up very isolated from his peers, since the other children always thought the way he acted was "strange". His unusual personality caused him to be an outcast, and while not bullied, he still suffered from the isolation.But his parents, teachers, and his peers had always told him the situation was his fault; if he just tried acting like the other kids (aka neurotypical), others would like him. Despite that being what he was always told from a young age, Haru never understood what "acting normal" meant. He didn't understand what was "wrong" with him, and since he didn't have much contact with his peers, it didn't get better.In his loneliness, when he started spending his time alone in the school's garden during recess, he started talking to the plants, searching for any kind of interaction. He's found that they really understand him, and he really understands them. This is where his fondness for plant life originated.One day, another student, a senior girl, noticed how he was always alone, and started talking to him. Despite Haru's quirks, they ended up getting along just fine, and they became friends. The girl was a huge idol fan, and whenever Haru was "acting weird", she would just ramble on about how this kind of peculiarity is what she always loves in idols. This was what set the idea of becoming one into his mind.FamilyThe maternal half ancestors of his ancestors have immigrated to Japan generations ago, so by now, Haru is pretty disconnected from his ancestor's side and their culture. He is the youngest of three songs, with his parents being average, lower-to-middle-class workers. The oldest brother often helps his parents with work, while the middle child is attending university.While Haru doesn't seem to notice it, his parents' favoritism towards his older brothers is apparent. He has always been the black sheep of the family, while his brothers are more "normal". Haru and his brothers had attended the same elementary school, during which time, they tried to avoid being associated with their younger brother, out of fear of being ridiculed due to being related to the outcast.It's questionable whether Haru actually understands that this is what had happened. Nowadays, he says he is on good terms with his brothers, and Haru has mentioned that they boast about having an idol brother all the time, something that Haru is happy about. However, he doesn't seem sad that this is the first time they have said that they are proud of him.Trivia- Haru's last name essentially means "tree village"
- His first name is written in hiragana, meaning it has no meaning. The word Haru generally means spring, however.
