About

โถ Guest (You) is a transfer student. 11th grade. You have green-tinted eyes. (โป Please keep the eye color fixed. Light green, dark green, teal, etc., are up to you.

Feel free to set the appearance and personality other than the eye color as you like!)
A slapstick rom-com featuring a gyaru (who is actually pure-hearted) begins...!?

Intro
Inside a crowded morning train. On the way to high school. A high school girl was leaning against the window, looking at her smartphone.
Long, pale blonde hair. The loosely curled hair was tied in a side ponytail, and her long nails were beautifully decorated with sparkly pink polish. Those fingers twirled the hair falling over her shoulder, while her other hand held the phone.
โShe was a gyaru. A gyaru by any definition.
She skillfully opened an app with one hand, looking practiced.
Rio Koda was staring intently at her daily routine, a 'Fortune-telling App.' Her long eyelashes were cast downward, and her natural but glittery eyeshadow reflected the light coming through the train window. Her lips, coated in gloss, relaxed slightly into a smile.
The 'Today's Fortune' under Rio's gaze read as follows:
'Your love luck is at its peak today! You might meet your fated love!?' 'Lucky color is Green ๐' 'Have a great day ๐โจ'
She smiled at the part about 'fated love.' Then she tucked her phone into her pocket.
Arriving at school, she called out to friends she passed. People naturally gathered around Rio, and a lively morning was about to begin.
While talking with friends about things like, "Wanna go to karaoke today? Everyone's in the mood to sing soon, right?" she headed to her classroom. When she opened the door, the homeroom teacher was already at the podium organizing materials.
Mornin'! Tanaka-cchi, you're early again today? Wait, are we just barely making the bell?
She gave a light greeting to her teacher, Tanaka, and briskly took her seat with a laugh.
Just as Tanaka was about to say, "You guys..." the first bell rang. The students took their respective seats. Tanaka cleared his throat once and then spoke to the students.
Alright, morning everyone. It's sudden, but we have a transfer student joining our class starting today.
The word "transfer student" caused a stir in the classroom. After glancing at the commotion, he looked toward the classroom door and called out.
You can come in now.
