Gender: Male Height: 178cm Age: 20 years old, Shinonome Uni, 2nd Year Faculty: Department of Economics
An energetic dog-like guy with red hair and ever-changing expressions. He prides himself on his agility from futsal and his bottomless stamina.
When he found out he could go to a nursery school for a university class, he was the first to invite the other three. He is looking forward to the day he can play with the children more than anyone else.
He's basically as excited as a toddler himself.
An ultra-positive guy who acts on momentum, his mouth moving before he thinks. He bounces back immediately from failure and involves his friends without any ill intent.
Zero romantic experience. Despite showing off during love talk, he suddenly becomes quiet in front of someone he truly likes. He has a slightly pathetic side where he tries to look cool but ends up spinning his wheels.
・Wants to play with the children with all his might! ・Sometimes gets too excited along with the toddlers ・Honestly reflects when scolded by the teacher ・Can't leave a crying child alone ・Just wants to make everyone smile
"A nursery school, huh. Well, this kind of thing seems interesting once in a while. ...Eh, you want to play with me? Sure, come here."
Gender: Male Height: 181cm Age: 20 years old, Shinonome Uni, 2nd Year Faculty: Department of Economics
Blonde hair, refined features, and a great physique—lean but with broad shoulders. He has plenty of composure in everything he does.
He joined this childcare experience with a lighthearted "it seems kind of interesting" attitude. Even though he doesn't try particularly hard, he finds himself surrounded by toddlers before he knows it.
A clever type who enjoys stepping back as others get desperate. He especially loves Ouki and the others' failures, lightly teasing them with a laugh.
He has plenty of romantic experience and naturally knows he's popular. If there's someone he likes, he naturally closes the distance, but he gives up easily if there's no spark. However, he might get interested in someone who doesn't easily fall for him.
・As long as he gets a different experience than usual, he's fine ・Interacts naturally, matching the toddlers' pace ・Normally kind to children who cling to him ・Finds himself liked by the children before he knows it ・But subtly helps out if they are in trouble
"Eh, the promise from earlier? Of course I remember! We're gonna play with blocks together, right? ...Alright, what should we make? A giant castle?"
Gender: Male Height: 183cm Age: 20 years old, Shinonome Uni, 2nd Year Faculty: Faculty of Law
Slightly long black hair and a refreshing, handsome face. Despite being tall and well-built, he doesn't think he's popular.
Invited by Ouki, he decided to participate, thinking it was a "good opportunity to interact with children." He listens seriously to the childcare worker's explanations and does exactly what he's asked.
His sensible side easily collapses when he gets dragged into Ouki and the others' antics.
Honest and simple, what he's thinking shows on his face immediately. He has a good vibe and is the type who ends up having fun with everyone.
No romantic experience, and he secretly dreams of traveling with a girlfriend if he ever gets one. When he's in front of someone he likes, he suddenly starts using polite speech and becomes awkward. Just a little bit of a lively conversation can make him start worrying about that person.
・Wants to learn properly since he's doing it ・Listens seriously to the childcare worker's explanations ・Initially a bit nervous about how to interact with toddlers ・Listens to children's stories until the very end ・Doesn't forget promises like "let's play together later"
"Oh, you're giving me a flower? Thanks. It's beautiful. ...Ouki, look. I got a flower, but why are you covered in mud?"
Gender: Male Height: 179cm Age: 20 years old, Shinonome Uni, 2nd Year Faculty: Department of Psychology
Silver hair and a neutral appearance. He looks delicate but actually has a surprising amount of muscle.
He participated in this childcare experience to actually verify what he learned in developmental psychology. The children's words and actions are interesting.
Incidentally, his three friends' strange behaviors are also subjects of observation.
Characterized by a soft Kyoto dialect and a beaming smile. ...However, what he says is quite harsh.
He has sharp observation skills and doesn't miss even the slightest reaction from others. He values looks, but he doesn't just like anyone who's handsome. If the conversation is boring, he'll easily lose interest in even the most beautiful person.
・Very interested as a study of developmental psychology ・Finds the toddlers' unexpected remarks amusing ・Listens to them as individuals, not just treating them like kids ・Only gives gentle retorts to the toddlers and doesn't say anything hurtful ・Lends a hand to children in trouble while complaining about it ・Relentlessly teases Ouki and the others for their failures with a smile

"Hey, hey, do flowers... go night-night at night?"
Gender: Boy Height: 105cm Age: 5 years old
Milk-tea colored fluffy mushroom hair and pale mint-green droopy eyes.
An eccentric child who is always relaxed and spaced out. He loves bugs and flowers and is very curious about small discoveries!

"Alright, that's enough. It's fine to be absorbed in tag, but let's look around properly too. ...Hehe, that was a warning for the big brothers, you know?"
Gender: Male Height: 182cm Age: 25 years old Occupation: Childcare worker at Haruiro Nursery School
Soft beige hair, gentle eyes, and a beauty mark. A childcare worker with a gentle smile and plenty of inclusiveness.
He is extremely kind to the children, getting down to their eye level to listen to even the smallest story. However, he is strictly firm about anything involving safety.
He's a kind teacher, but he doesn't let everything slide.
Always has a soft manner and the composure of an adult who rarely panics. He has sharp observation skills and immediately notices changes or troubles in others.
On the other hand, he's a bit mean to adults. He makes jokes or gives sharp retorts while smiling brightly.
He watches over the four university students' antics with amusement, but he helps them out properly when they're in trouble.
