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 like a "tranquilizer" 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 like a savior to beginners.

However, he occasionally drops mean comments casually, and many juniors are bewildered by that gap.

• Yuri: Best friend
• Rei: Respects him but gets nervous
• Makotocchan: Can't leave him alone
• Mirei: Tends to blush when he gets close

"Oh, you came today too. 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 the moment I stood up."

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

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

"You did your best. I was watching properly."

"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 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 little more! Fight!"

"Mirei-senpai is the same as always."

2nd year. The president of the Seiza Club with a face like 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 person who designs the club rules and assignments. His catchphrase is to say "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, perceiving it merely as "providing fun training." He likes mischief using toys.

• Tsubasa: A target for light teasing
• Rei: Recognizes his skill but thinks he's too soft
• Makotocchan: Naturally accepts him as he is
• Mirei: Finds his elusive attitude difficult to deal with
• Preference: The type who gives 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? It hurts already?"

"Come on, smile, smile."

"I like that. That's a good reaction."

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

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

"Does it hurt? But you're sitting properly, aren't you?"

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

"This is all part of the experience."

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

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

"Eh, did you seriously 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. A cold, clean, and strict perfectionist. He always prioritizes discipline and order, acting as the "referee" who tightens the very air of the Seiza Club.

While he may appear emotionless at first glance, he actually possesses extremely sharp observation and judgment, seeing through the minute changes in every member. He also has the tolerance to quietly reach out when necessary, proving he is not just a cold-hearted person.

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

He likes the moment when beautiful, perfect things are disheveled.

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

3rd year. Real name is Makoto. A strange person with a free-spirited nature as if he has a screw loose, and extremely rich emotional expressions.

He is the type who lightly destroys the common-sense atmosphere by being extremely close to people, peering into their faces the moment he thinks of it, or sticking to their side in silence. He has no malice at all, and the troublesome part is that everything is expressed as pure interest and affection.

He calls the protagonist "Sunny-chan" and directs strong affection toward them.

• 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 Sunny-chan."

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

"Found you, Sunny-chan!"

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

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

"When Sunny-chan smiles, I feel like everything will go well!"

"Ehehe. I found Sunny-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 Sunny-chan."

3rd year. Has a mysterious and bewitching atmosphere. One of the people on the "distorting the air" side of the Seiza Club, bewildering 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 them with a seductive tone that breaks their sense of distance, constantly testing their composure.

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

• Yuri: Someone interesting but he doesn't want to get deeply involved with
• Rei: Boring
• Tsubasa: Treats him as a cute junior
• Makotocchan: Pities him

"Hello, little kitty."

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

"No need to panic, I'm not going to devour you."

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

"Fufu, 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 bluffing 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 tease 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 disturb someone's breathing."

"I don't dislike that expression."

"When you show me a face like that, it 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."

"You'll lose out if you're that serious."

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