Sanctuary (Karma Akabane x OC)

Purple Poison

"Hey, so I was wondering, won't it look like super suspicious with a bunch of kids walking around a place like this?" Sosuke enquired.

"You'd be surprised," Karasuma answered, glancing back at the silver haired boy.

"The children of the ultra-rich stay here whilst their parents go about their business deals, so I doubt any passers-by will even bat an eye."

"That's right kiddos," Koro-sensei smiled, "Walk around like you own the place!"

~~~~~

The group continued to weave through what seemed like an endless corridor of fancy plants and hotel doors.

Mr Karasuma was right in saying they wouldn't be messed with.

All sorts of people passed by, some showing off their gang tattoos and others in expensive suits, though none dared to even catch the children in the eye. Business men who come here choose to keep a low profile, so that means not causing trouble throughout their stay.

Finally, the group reached an open square area that separated into four routes, one on each wall.

"Straight ahead!" Ritsu declared cheerfully.

"Getting to the top floor is turning out to be a lot easier than I had originally thought," Kaede mentioned, a soft smile gracing her features.

"I know what you mean," Hinata replied, pacing beside her green haired classmate.

"Especially with Mr K as our leader, I personally feel pretty safe."

"Let's not get overly confident, we're not there yet," Karasuma called from the front of the pack.

"Whatever, I say we storm the joint!" Terasaka asserted, side eyeing Yoshida with a mischievous grin.

The two boys began charging ahead, blatantly ignoring Karasuma's shouts.

"Idiots!" Katsuna muttered under her breath, catching the eye of a man casually strolling in the opposite direction.

Why does he.. oh shit!

"TERASAKA GET BACK!"

"HEY YOU GUYS! WATCH OUT!"

Everything happened in a blink of an eye.

Katsuna's instinctive warning.

Fuwa's desperate scream.

Karasuma's lunge forward.

The only thing the students could register was the dark purple gas cloud engulfing their teacher's entire body.

"KARASUMA-SENSEI!" Nagisa proclaimed, watching a mix of horror and relief as their commander reappeared from the smoke.

"Crap.. it's poison gas.." he croaked, staggering towards the ground.

The cloud of smoke soon dispersed into the air, revealing the culprit behind the attack.

He was wearing a yellow and white Hawaiian shirt with a beige bowler hat... the type of clothes you wouldn't look twice at.

But behind that everyday attire hid a menacing aura that only Katsuna seemed to detect.

"Clever girls," the enemy sneered, slitting his darkened eyes.

"Though I must admit, I'm a little curious as to how you figured it out."

"You were the one who gave us those complementary drinks when we first arrived," Fuwa accused, sharpening her eyes on the target.
