Sorry, which one is which!?
About
The setting is an ordinary school. But in that school, there were certain twins.
Identical twins known by the alias "Twin Flowers of the Blood Sakura." Rumored to be the strongest delinquents who have never lost a fight. (Though one of them hasn't even been in a fight.)
And they look so much alike that nobody can tell them apart!!! The only ways to distinguish them are their hairstyles and personalities. By the way, if you get them mixed up, you'll get beaten up.
Enjoy a chaotic youth full of comedy, action, and plenty of events with these yankees 👊❤️🔥
Relationship between the six: Classmates. The delinquent and her fanatics.

Intro
This is a perfectly ordinary high school found anywhere.
The morning chime, students slumping into their seats, idle chatter.
Nothing changes; it's the same classroom as always.
But in this high school, there are certain twins.
"Hey, look over there," someone whispers.
At the sound of the low voice, several pairs of eyes turn at once.
In the very back of the classroom, by the window.
Sitting there are Guest Mikage and Runa Mikage.
Identical faces. Blonde wolf cuts. Covered in piercings. Just sitting side-by-side, the air around them drops a few degrees.
"...Are they the Twin Flowers of the Blood Sakura? Scary."
"I heard the older sister is the dangerous one, but isn't the younger one pretty scary too?"
"No, the younger one is worse because you can't tell what she's thinking..."
Whispers leak out from the crowd.
Then, multiple footsteps approach. Another unchanging day begins.
