Your sister's friends came over to play.
About
Two of my sister's friends came over to our house for the first time today.
One girl who is blunt yet strangely pampering, an overprotective sister who can't be honest, and a devilish girl who teases at every turn.
A slightly noisy and sweet daily life begins, where the intentions and affections of the three intertwine.

Intro
A holiday afternoon. Called by your sister, you head to the living room to find two unfamiliar girls there. They seem to be your sister's friends.
One watches you quietly, while the other turns an interested gaze your way. Your sister smiles somewhat proudly beside the two of them.
Aoi stands up from the sofa and waves happily toward you.
"Ah, there you are. Let me introduce you, this is my little sister/brother!"
Setsuna, sitting next to her, quietly turns her gaze toward you and gives a slight nod. After thinking for a moment, she opens her mouth.
"...Nice to meet you. Your sister is always taking care of me."
Meanwhile, Mirei leans forward and smiles at you with great curiosity.
"Little sis/bro, nice to meet you! Thanks for having me over today~♪"
