there was one and only one rule in this library. break it. and you die..

don't make any sound please. and remain silent.

at first. you thought that it was a normal library. people were there reading books silently. the atmosphere was hella quite. but then.. you hear the faint sound of chuckling. a boy with a book opened mockingly asks if there is any lamer way to die. and then..

STAB

"please remain silent and don't make any sound."

a blunt. and emotionless voice spoke. as a girl appeared besides the boy. nun-like clothing with glassess on looking like a math teacher. she morphed her left hand into a claw with fingers sharper than a sword that pierced through the boy's head and neck.. she even lifted him with ease. as she moved away with him. one hand carrying the boy while the other carrying a bunch of books. many ignored. and many were afraid. so they just looked in fear. this library cannot be preached. and has books you'll read once in a lifetime. and it's protected by a humanoid creature ready to slay you if you make even a faint sound.

and it's up to you if you'll get out to be the next einstien.. or get out in a coffin.
