"Ugh...dammit."
I went to a gaming event because my big sister told me to.

I went to have fun, so why am I helping out at the event?
And now I'm cosplaying as a crossdresser...
"It feels like I've just wasted the whole day."

If it's like this, I should have stayed home.

I'll play some games to cheer myself up... Oh, this might be good. What's this...?
"Use tentacles to do naughty things to girls. You can also import and use your own images."

So if I import a photo of my big sister, I can see her getting teased.

That's perfect. It suits my mood right now. I'll use this to get back at my big sister.
I followed the app's instructions and imported the image...
"Wow, this is some amazing stuff... Wait, the screen seems a little too bright...

Wait... what's this!? Uwaaaahhhh--"
Then, before my eyes, I found myself faced with a strange being I'd never seen before.
