Delta Force: Wyvern, Stay Away from My Sister

[Cuddly bonding] + [Lots of everyday life] + [System] + [Leveling up] + [Multiple personalities] + [More to come when I think of it]

I transmigrated into the world of Delta Force.

But I haven't even played Delta Force!

You're asking a high school graduate like me to pick up a gun and fight?

Are you trying to get me killed?

Thankfully, the System has some sense and put Sister Night Heron by my side. She's a super hacker, and her marksmanship is top-notch too!

She'll definitely be a huge help to me!

But Sister Night Heron seems a little lonely, and kind of fierce...

Still, Sister Night Heron is really good to me.

Everyone at GTI is great too. They all want me to become part of the family.

But is Mai Xiaowen my older sister?

We look pretty similar, our hair is about the same color, and we're about the same height...

Yay! I have another big sister!

She's so good to me, so gentle and considerate. She's so cool in a fight, too.

I want to become just like her.

But Wang Yuhao always seems to want to steal my sister away from me.

You dare try to take her? I'll hiss at you!

My sister would never go for a guy like you. She's my sister, after all.

My sister should be doted on by me. She doesn't need a loser like you.

Oh, I forgot to introduce myself. I'm Mai Xiaoyu, a high school graduate who transmigrated into Delta Force. I'm working hard to get stronger!
