Sunny and Outgoing Big Girl [Infinite]

The first player's identity is mysterious. They seem like a powerful veteran who's here to carry the team.

The second player is an invisible nobody whose hobby is showing off.

The third player is always coughing up blood, but when it comes to using a gun, he's better than anyone.

Finally, everyone turns to me and asks what role I'm playing.

I look at my identity and say, "I'm a sunny, cheerful girl."

My only special skill is smiling. Look at the corners of my mouth turning up.

Please note:

A comedy-style unlimited-flow story. The heroine really is a sunny, cheerful girl. She clears stages by slacking off and gets carried the whole way.

As always, it's a harem Mary Sue story. The three powerful male leads argue over who gets to carry her.
