Toilet-bound-Killua-Kun!

"Have you heard of the legend of killua-kun? They say she has a bob and red overalls. She's on the 3rd floor of the old building,in the 3rd stall in the girls bathroom.You can summon her right now if you want! She'll grant you any wish no matter what it is! But, She'll take something precious from you in exchange and you won't know it until it's already gone..."

Gon crept I to the bathroom as the floor boards creaked under him. 'This better be worth it..!'

"To call her you must knock 3 times on the stall door..."

Knock

Knock

Knock

"Then you must say..."

Gon gulped. "Killua,Killua,...Killua..are you in there?." Asked gon. There was nothing but silence for a bit as gon looked around. The young boy whimpered and closed his eyes.
"Heeeellllooo~" a voice said from the stall
Gon gasped and took a step back from the stall as he watched it slowly open. When he peeked in he was met with...nothing?. Gon let out a sigh of relief. "Ok I'm just hearing things-" "you summoned me?" "Ah-! Hah!" The young boy turned around,trying to hit the ghost in the face only for his hand to go through. "Ah?!" He pulled his hand away. The ghost giggled. 'I thought Killua was a girl? That's sounds like a male voice...'
"What's the matter with you?" The spirit asked with a playful voice. 'I can see right through him! He's wearing such an old uniform- are those orbs?!!' "Are you a ghost?" Gon chirped. "Hmm...I prefer apparition you know....or-" killua sat down. "The seventh of the seven wonders of the school! Killua the bathroom ghost! Pleasure to meet you~"
