Hey guys I'm back with another kaito x Len fanfic. Hope you enjoy it.
-------------------------------------------------
"Leeeeeennnnn" rin shouted as she made her way up the stairs up towards her brothers room. " ugh, what now? If it's another maid outfit you want me to try out then it's not happening!" Len furiously spoke to which his sister just smiled   Innocently. "Drink this!" She pushed a small bottle onto lens face. Len snatched it from her hands and examined it.

It was a clear glass bottle with somewhat sparkly yellow liquid and a yellow ribbon tied to the opening. "What is this?" Len asked out of curiosity. "It's an energy drink. I bought it especially for Len." Rin smiled. Len sighed and opened the bottle not wanting to let his sister feel bad.

He took a slight sip and was almost surprised at how good the taste was. Then, before he knew it, the whole bottle was finished. "How was it?" Rin asked excited. Len rubbed his eyes in sleepiness " surprisingly good. But I suddenly feel...sleepy..." Len spoke feeling himself growing tired and week. "then  sleep silly!"  Rin joyfully spoke leaving the room for her brother sleep.

LEN'S POV:

" ugh! For how long was I asleep!?" I yawned and stretched. Hmm. Something doesn't feel right. I looked to my side to find a tail...my tail...! Why in the world is that there!? I ran my hands through my hair finding out that somehow I had developed cat ears as well. Right. This definitely has something to do with the drink that rin gave me.

" nyaa!!" I shouted. Wait..." Nya?" W-what's wrong with my speech? "Nya! Nya!" I was speaking fine a second ago. Why can't I speak!?
I quickly climbed out of bed and particularly stumbled towards rins room. What in the world is happening to me!? I need an explanation!!
