Ninjas Stick Together. (Randy Cunningham X Reader)

(I got this entire idea from a picture, I am stupid af.)
"Uh...hey...you know me. (Y/N) (L/N), but there's two things you don't know. But...you need to promise me...you will never tell anybody."
"I promise."
"Good, now, listen, I...I'm a Neko as people call me... I just wear this hat to keep my ears hidden...a-and...well, I'm...I'm a ninja."
"WHAT!?"
"Mhm, a ninja, just like that other guy...I don't know who he is...but we're both ninjas. I thought there was only supposed to be one...but somebody clearly has other plans."
"The book?"
"Yeah, how did you know?"
"Uh...lucky guess."
"But can you promise me...please promise, you won't tell anybody I'm a ninja?"
"I promise."
"And you promise not to tell anybody I'm a Neko?"
"I promise."
"Thanks Randy. That's why your my best friend."
"Your my best friend too (Y/N)!"
"Oh shut up!"
