Looking for a particular Anime

[Rapidsom]

I know this is next to nothing to go on but does anybody know the name and the episode of an anime I'm about to describe a scene out of. There are 2 girls 1 of them has a gun/rocket launcher thing and shoots the other with it. it shoots out like a bandage which wraps them both up. some spark switches both the characters into each others bodies. I know it's a massive long shot but if anybody knows I would be super grateful

"Massive long shot". Was that an unintentional pun? Also, I have no idea what that anime is.
