Sister scenarios: Diabolik Lovers

Riddles (ft. Reiji, Ruki & Ayato)

"Ok, how about this. The more you take, the more you leave behind?"
"You are choosing the easiest ones, it's footsteps."
"Fine, let me keep thinking, oh I know maybe there's a riddle book here. I mean, it is a library after all," you stood up from your seat and look around.
You were waiting in the library for Ayato because he had something on and Reiji made you stay because he knew that you didn't want to come. Isn't he a great brother? 
You got bored and stared telling him riddles and is still unbeaten.
"Hello y/n," you turn slightly and see Ruki looking in the bookshelf.
"Hey," is all you say as you see a book called 'Riddles.'
"How much sand is there in a hole with the radius of 22.34m and 12.59m in height?"
"Nothing," you hear two voices say at once. You look up and smirk.
"Looks like another competition."

You sit down on a two person desk with Reiji and Ruki on each side and you in the middle. You found some bells and are using them for the buzzers. So far, it was even.
"Poor people have it. Rich people need it. If you eat it you die."
You here both bells go off. Honestly you're just surprised that Reiji hasn't left yet.
"Ruki." "Nothing." "Correct, again, for the millionth time," you say, your voice getting softer as you talked.
"Ore-Sama is here," you hear Ayato yell.
"Ok," you close the book and look up. "Whoever gets the best answer wins the whole match, agreed?"
Both of the nod.
"How do you make Oreo-Sama shut up about himself?"
"Tie him down to a chair and get Laito to give him a lap dance."
"Turn him into one of Kanatos dolls with a nice pink dress and make up done by Subaru."
"What about make up and Subaru?"
"Nothing," you say while trying to hold in your laughter.
"They were both great answers, it's a draw,"
"What!" They stare at you in disbelief.
"I bet I could've won," Ayato said proudly.
"What gets wetter the more it drys?"
"Um,"
"A towel" Reiji and Ruki said once again at the same time.
"That one was a difficult one."
"It's the easiest in the book you stupid Oreo!"
"Hey!"
