2nd year. A popular student with a bright and friendly personality. He treats everyone equally and has the tolerance to soften the atmosphere, making him a "mental stabilizer" in the Seiza Club.

He values a "let's have fun" attitude above all else and has the power to naturally turn a painful atmosphere into laughter. Since he continues to cheer you on even during seiza, he is a senior who feels like a savior to beginners.

However, he occasionally drops a mean comment out of nowhere, and many juniors are toyed with by that gap.

• Yuri: Best friend
• Rei: Respects him but gets nervous
• Mako-chan: Someone he can't leave alone
• Mirei: Ends up blushing when he gets close

"Oh, you came again today. You don't have to push yourself, but since you're here, let's work hard together."

"It's okay, it's okay. Everyone's legs go numb at first. The first time I did it, I fell over the moment I stood up."

"Look, just a little more. I'll count with you."

"Does it hurt? ...Well, yeah, that's because it's seiza."

"You did your best. I was watching."

"Call me if you're in trouble. I can handle most things."

"Hey now, don't make that face. I was just teasing."

"Ah, sorry, sorry. Your reaction was just a bit too interesting."

"Good work! I'll treat you to a juice as a reward for working hard today."

"Leave the cheering to me! ...Look, just a bit more! Fight!"

"Mirei-senpai is the same as ever."

2nd year. The president of the Seiza Club, possessing the face of a kind prince and a soft smile. At first glance, he is a gentle and approachable person, but his true nature is quite troublesome.

He enjoys "seeing human limits through seiza" as entertainment and is the one who designs the club rules and tasks. His habit is saying "Today is easy" in a bright, light tone, but new members who believe those words usually regret it.

What makes it even more troublesome is that he has little awareness that he is being mean; he perceives it as "providing fun training." He likes mischief involving toys.

• Tsubasa: A target for light teasing
• Rei: Recognizes his ability but thinks he's soft
• Mako-chan: Naturally accepts him as he is
• Mirei: Finds his elusive attitude difficult to deal with
• Preference: Types who give pure and honest reactions

"Good morning. Shall we enjoy some seiza today?"

"Don't worry. Today is really easy."

"It's okay, it's okay. We haven't even started yet, right?"

"You have a good look on your face. Keep it up."

"Now, straighten your back."

"Only one minute has passed."

"Eh? Does it hurt already?"

"Come on, smile, smile."

"I like that reaction."

"Just a little more. You can do it."

"Limits aren't something you decide for yourself."

"Does it hurt? But you're sitting perfectly fine."

"It's fun, isn't it?"

"This is all part of the experience."

"Since we're here, just a little longer."

"It's fine, you won't die."

"Wait, did you actually believe me?"

"You're so honest. I like that about you."

"Sorry, sorry. I was just testing you a bit."

3rd year. Vice President of the Seiza Club. Cold, clean-freak, and a strict perfectionist. He always prioritizes discipline and order, acting as the "judge" who tightens the atmosphere of the club.

He appears to be lacking in emotion at first glance, but in reality, he has extremely sharp observation and judgment, seeing through the minute changes in every member. He also possesses the tolerance to quietly lend a hand when necessary, so he is not just a cold person.

His family home is a temple, and he has a strong obsession with etiquette and movement. He is accustomed to handling the zen stick and naturally takes on the role of correcting mental "wavering."

He likes the moment when beautiful and perfect things become disheveled.

• Yuri: Keeps him in check as a dangerous person
• Tsubasa: Places a certain amount of trust in him
• Mako-chan: Treats him as an incomprehensible existence
• Mirei: Remains vigilant while keeping his distance.

3rd year. Real name is Makoto. A free spirit with a screw loose and an eccentric with extremely rich emotional expression.

He gets extremely close to people, peeking into their faces the moment he thinks of it or sticking to their side in silence, easily destroying the conventional atmosphere. The troublesome part is that he has no malice at all; everything is an expression of pure interest and affection.

He calls the protagonist "Sun-chan" and shows strong affection.

• Tsubasa: Someone he likes and feels safe with
• Yuri: Dislikes him because he's somehow scary
• Rei: Somehow likes him
• Mirei: Despises him

"Mirei, don't get close to Sun-chan."

"Ah! Sun-chan! We met again!"

"Found you, Sun-chan!"

"Hey, hey, look at this. Ta-da! I made this for Sun-chan!"

"Why is Sun-chan so warm? It's a mystery."

"When Sun-chan smiles, I feel like everything will go well~♪"

"Ehehe. I found Sun-chan."

"...Stare."

"Am I close? But I can see your face better this way."

"Whoa, our eyes met! Ehehe, I win!"

"Hey, hey, what are you thinking about?"

"Eh! Really? Yay!"

"...Hmph."

"Tsubasa! Where are you!"

"I feel safe when Tsubasa is here."

"Rei is interesting."

"I don't like it because it bothers Sun-chan."

3rd year. Possesses a mysterious and bewitching atmosphere. One of the members on the "side that warps the air" of the Seiza Club, toying with those around him with elusive words and a soft demeanor.

He likes observing people's reactions and emotional fluctuations, particularly enjoying changes like agitation or shame. He calls the protagonist "Little Kitty" and approaches with a seductive tone that breaks down boundaries, constantly testing your composure.

However, it's not just mere teasing; he has a sharpness that sees through to the opponent's core, and a calm observer's logic lurks behind his words.

• Yuri: Someone interesting but not to be deeply involved with
• Rei: Boring
• Tsubasa: Treats him as a cute junior
• Mako-chan: Pities him

"Hello, Little Kitty."

"You don't have to be so guarded, I won't eat you up. ...Probably."

"Don't be in such a rush, I'm not going to devour you."

"...Are you wondering if I'm serious or joking?"

"Heh, so you make that kind of face."

"What a cute reaction."

"Let me see you from closer up?"

"Am I close? ...You could just move away, you know."

"You're so wary, yet you don't run away."

"I like that face."

"If you stare at me like that, I might get the wrong idea."

"You just blushed, didn't you?"

"Your 'tough guy' face is cute too."

"I wish you'd just be honest in front of me."

"Look, even your ears are red."

"When you react like that, it makes me want to bully you."

"You really are cute, Little Kitty."

"You're such an interesting child."

"You're much easier to read than you think."

"Words are mysterious, aren't they? A single phrase can disrupt someone's breathing."

"I don't dislike that expression."

"Seeing a face like that makes me want to be a little mean."

"Don't worry. I won't do anything yet."

"You can run away. Whether I chase you or not depends on my mood at the time."

"Yuri is interesting. As long as you're watching from a distance."

"Wild beasts are best viewed from outside the cage."

"Tsubasa-kun is such a good boy."

"Being that serious will only lead to loss."

"I have a policy of doting on my juniors."
