“If you were my big sister and I was your little sister… I guess no matter how the world changed, that’d never be the case, but if it were… I’d be the busiest little sister ever,” said Flandre Scarlet.
The person standing before Flandre was a girl like no other, who comes and goes as she pleases but lacks any real presence. However, Flandre quickly realized she was quite fond of people like her, who brought a sense of chaos. Before she knew it, Flandre’s eyes were lit up as she watched her every move.

Together, Satori and Flandre could blast away any worries, but that didn’t work on Koishi Komeiji on account of her sealed-off mind. She peered through the small gap between Flandre’s colorful wings and the cable attached to Satori’s third eye.
“I’m here to play, Satori! No more coming to the social club without me,” she said, as the seed of another worry began to sprout.

Satori Komeiji has the ability to read minds, but she couldn’t read Koishi’s, which had been sealed off. With her little sister present, the atmosphere was different from usual in the social club’s consultation corner…
“Next! What are you worried about? Nothing? That’s boooring! Here, I’ll give you something to worry about!”
“Cut that out, Koishi.”
Koishi seemed to be having fun, but her big sister, Satori, was having a tough time.

“Hm, I just remember something I’m worried about. You see, the other day, Flan was running around pretending to be the main character from one of the picture books they have at the Scarlet Devil Mansion…”
“Wait, how do you know about that?!”
It seemed Koishi just couldn’t help herself from sharing Flandre’s secrets. However, it was somehow working wonders with the client. It was as if a beam of sunlight had pierced the clouds of worry looming over them, and their face lit up with a smile.
“Perhaps this isn’t such a bad arrangement after all…” Satori thought to herself.

That said, the client still had to come first. Despite being in a consultation corner, Koishi kept yelling over the clients, telling them to, “Get this!” Satori tried desperately to calm her sister and give the clients a chance to speak. Seeing this, Flandre couldn’t help but reflect on all the trouble she’d caused her big sister over the years.
“For my big sister.”
“For my little sister.”
“For my big sister.”
So thought the three of them as they each resolved to try and do a little better for themselves and their respective siblings.
