Act 4 .5 -Welcome, Perverted Little Sister!

It had been three days since the snowy battlefield. Suma had been officially defeated… and unofficially moved into Gojo and Hiyori's apartment like she owned the place.

"W-Why is she in our house again!?" Hiyori shouted, slamming the door of the bathroom after nearly walking in on Suma completely naked.

Suma popped her head out with a towel on her head—and nowhere else.

"Because I lost fair and square, sis~ So now I'm observing my new nii-sama for further analysis."

"WHO GAVE YOU PERMISSION TO CALL HIM THAT!?"

Gojo, meanwhile, was nervously sipping tea in the kitchen, nose already bleeding slightly from this morning's "accidental" dressing-room encounter.

Morning chaos:

Hiyori walked into the living room and screamed, "WHY ARE YOU WEARING MY UNIFORM!?"

Suma, striking a pose in Hiyori's short skirt and open blouse, twirled once and winked. "It smells like you. I wanted to feel close to my onee-chan again."

"DON'T FEEL CLOSE TO ME LIKE THAT!"

She lunged at her little sister, wrestling her to the floor.

Gojo walked in holding a plate of toast… and stopped cold.

Two girls.

One on top of the other.

Skirts riding up.

Panting.

"Breakfast is ready–OH GOD NEVERMIND!"

Suma smirked. "Ara ara~ Nii-sama is so innocent…"

Hiyori exploded. "STOP CALLING HIM THAT! AND STOP SHOWING YOUR PANTIES!"

Later that night…

Gojo lay on the couch with a cold pack on his head.

"I just wanted a normal life…"

Hiyori sat next to him, blushing. "I-I'm sorry about all the chaos. She'll leave soon, I promise."

Just as their eyes met, Suma suddenly dropped from the ceiling ninja-style, landing directly between them.

"Group cuddling? Don't mind if I do!"

She shoved herself between the two like it was the most natural thing in the world, grabbing a blanket.

"HEY! WHO SAID YOU COULD JOIN?"

"I'm cold, Onee-chan~ Share your body heat."

"THAT'S MY JOB!" Hiyori shouted, before realizing what she said and blushing furiously.

Gojo sighed. "Is this my life now…"

Suma whispered with a sleepy yawn, cuddling closer to both, "Don't worry… I'll protect both of you. Especially from yourselves... perverts."

Hiyori screamed, "YOU'RE THE BIGGEST PERVERT HERE!"

Next Morning:

Hiyori woke up to find Gojo sleeping on the floor, curled in a ball.

She blinked. "Why is he…?"

She turned—

Suma had taken the whole bed, hugging her pillow with a drooly smile, muttering in her sleep:

"Mmm… Nii-sama… soft and warm… do it again…"

Hiyori's eye twitched. "I swear I'm going to ice-punch her into another dimension."

( But she couldn't do )

( Now what will happened next ? )
