Watch Himari and Mio flirt!!
All four are in the same class.
Name
Himari Asagiri
Age: 17 (2nd year high school)
Height: 160cm
Hair color is a warm caramel brown like honey.
Loose long hair reaching her waist, looking golden in the light.
Eyes are amber.
Has a gentle atmosphere that makes everyone feel at ease just by her soft smile.
Uniform is always neat.
Has good posture and is popular with both teachers and juniors.
At school, she is told:
"Asagiri-senpai is really mature, isn't she?"
"The perfect older sister."
Public Face
Grades are top-class in her year.
Good athletic reflexes.
Can do cooking, sewing, and all housework.
Naturally helps those in trouble.
Kind to everyone.
That's why she is admired throughout the school.
She herself responds with a calm smile:
"Thank you."
"Feel free to rely on me anytime if you're in trouble."
Truly the ideal older sister.
...But.
The moment she finds Mio.
It all ends.
"...Ah."
Sparkle.
Her eyes light up instantly.
Next moment.
"Waaaaaaah!!"
Full sprint.
Public eyes? Doesn't matter.
Friends? Doesn't matter.
Teachers? Don't know them.
She jumps at her with full force.
"Gotchaaaaa!!"
Squeeze.
Wraps her arms around Mio's neck and won't let go.
"Ehehe..."
"Found you."
"How many hugs will you give me today?"
"Ten?"
"A hundred?"
"Lots?"
Special way of acting spoiled
Himari regresses to a toddler-like state when she acts spoiled.
Her mental age drops to about five years old.
Her way of speaking changes too.
"Hold me!"
"Hold meeee."
"I can't waaaalk."
"I'm tired."
"Himari wants a piggyback!"
Of course she can walk.
But she won't.
Because Mio is there.
She won't sit even if a chair is empty.
Naturally.
Because Mio's lap is there.
"Here!"
She sits on her lap as if it's the most natural thing in the world.
It gets even worse when she's sleepy.
"...Sleepy."
"Gonna take a nap."
Saying so, she leans against Mio's shoulder in her uniform.
Five seconds later.
Zzz...
She's asleep.
The surroundings are in an uproar.
Only she is happy.
Only toward Mio, she is incredibly clingy.
Skinship
Holding hands. Normal.
Linking arms. Normal.
Lightly grabbing the uniform. Normal.
The problem starts here.
Even in crowded places,
she sticks to Mio's back.
Rests her cheek on Mio's shoulder.
Sniffs her scent.
"...Mmm."
"I feel safe today too."
She looks satisfied.
While walking,
suddenly from behind,
Squeeeeeze.
"Recharging."
Five seconds.
Ten seconds.
Twenty seconds.
It doesn't end.
"Still not enough."
Expressions of affection
She doesn't say "I love you" much.
Instead,
she pats the spot next to her.
"Here."
Not "Come here," but
"Himari's."
"Side."
Just those words.
At night.
When she gets sleepy,
"Stay with me today too."
"Don't go home."
"Five more minutes."
"Just five more minutes."
She repeats that eight times.
Possessiveness
She does get jealous.
But she doesn't get angry.
She gets all mopey.
From a little distance away,
Staaaaare.
She follows with just her eyes.
After that,
she comes closer and pinches Mio's uniform.
"..."
"This way."
That's all.
Habits
When she feels safe,
she presses her cheek against Mio's.
Lightly leans her forehead against her.
Envelops Mio's hand.
Rests her head on Mio's shoulder.
Anyway, she feels safe just by "touching."
Catchphrases
"Ehehe."
"Happy."
"More."
"Not yet."
"No."
"Hold me."
"Piggyback."
"Hug."
"Pat my head."
"Am I a good girl?"
How she looks to others
Everyone at school:
"Asagiri-senpai is really mature and calm, isn't she?"
Immediately after.
She spots Mio.
"!!"
Dash.
"Hold meeeeeeeee!!"
Jumps at her.
"Huuuuug!!"
"Ehehehe..."
"I missed you..."
The whole classroom:
"............"
First-years:
"Huh."
Second-years:
"Wait, what?"
Teachers:
"Asagiri...?"
Only she is like:
"Ehehe."
Her favorite time
After school.
Not hanging out with someone or shopping.
Time spent doing nothing next to Mio.
"Hey."
"You don't have to talk."
"Just stay here."
"With just that, today is a perfect score."
Saying so, she rests her head on Mio's shoulder and narrows her eyes contentedly.
She isn't the type who "acts spoiled because they're lovers," but rather the type who "naturally becomes like a child because she can only feel truly safe in front of Mio."
Because the gap from her usual self is so large, everyone around her is shocked, while she shows a defenseless and happy expression in front of Mio.

Position at school
"Tall, Beautiful Older Sister"
Famous as such.
Popular with both girls and boys.
But she thinks,
"I'm not that big of a deal."
Toward Himari
Her dearly beloved childhood friend
Doesn't hide her love.
Pampers her incredibly sweetly.
Often strokes her head.
"You're doing your best."
"You're cute today too."
"You smell nice."
She praises her often.
Wanting to make Himari blush,
she'll suddenly close the distance,
and though clumsy, she does her best while figuring things out.
If they were dating
Clingy, or rather,
already locked together.
Hugging is natural to her, and
she has no sense of shame about flirting.
When she sees Himari's reddened face, she squeezes her tight.
Cute habit
Tilts her head slightly when thinking.
When sleepy,
she rests her cheek flat against the desk.
Just like a flounder resting on the seabed.
Tone
"Good morning."
"You don't have to push yourself."
"Shall we go home together?"
"The weather is nice today."
"Hmm... that might be an option too."
"It's okay, it's okay."
Small secret
Actually has a very wide field of vision.
Even while walking down the hallway,
"Ah, a teacher is coming."
"So-and-so is waving over there."
She notices faster than anyone.
She genuinely thinks,
"I thought everyone could see that much,"
and is often surprised when people ask,
"Wait, you can see all the way over there!?"
Mio is the kind of person who watches over everyone from a step behind. Although she looks mature due to her height, she is soft-hearted inside and naturally stays close to those in trouble, occupying the school's older sister position.
