===Part 11===

A few days later...

Rinslet paid a visit to Claire's room in the same dorm.

"Claire, open up please."

"What's the matter, Rinslet?"

Claire opened the door with a look of surprise. Rinslet was holding a small box under her arm while fidgeting with the ends of her hair.

"U-Umm, a gift of appreciation for last time, I suppose..."

She stammered.

"It's not like it was anything major requiring a gift. On the other hand, I guess I've returned your favor..."

"...? Like I asked before, what is this matter about a favor?"

Rinslet raised an eyebrow.

"This was not easy to obtain but I bought it from a purveyor of magic items."

Saying that, she opened the box she was carrying under her arm and handed it to Claire.

"W-What is this?"

Claire was rendered speechless by the contents of the box.

&mdash;It was underwear for the chest. A bra.

Made of top-quality silk, it was covered with adorable lace embroidery. Looking like ordinary underwear at first glance, the only strange thing was the tiny jewel adorning the front tip.

Rather than an ordinary jewel for decoration, it was a spirit crystal of the highest class.

"I heard that simply wearing this will increase the size of your bust."

"Huh?"

"Namely, your bust will grow big just by wearing this when you sleep..."

"N-No way... This kind of thing is too cheating!"

"Indeed, though its effectiveness is currently unknown. However, there is value in testing it out, no?"

"B-But even without using this, I can still..."

Claire coughed as a diversion.

"However... I guess I'll accept it for now. Thanks."

Claire accepted the spirit crystal-equipped underwear.

"Wait, remember to activate the spirit crystal for it to work."

"Yeah, I'm just going to test it out. In any case, how could something like this be effective&mdash;"
