My Rat Is an S-Class Awakener

I got thrown into another dimension, wearing nothing but my pajamas. While everyone gets a Status Window and all these fancy powers, I’m stuck with only a system error. Oh, and my pet rat somehow came with me. Except… he’s not a rat. He’s a beastman, and not just any beastman, but a ridiculously powerful, S-rank Awakened beastman! And now he’s in love with me.
“What can I do to make you like me, Soyul? I’ll do anything! I’ll even crawl inside a cat’s mouth if you tell me to!”
“I’m pretty sure the cat will faint if an S-rank rat of all things did that.”
