Ranna what the fuck was that?
She's getting way too little face time.
This is what eventually has to happen to a completely overpowered character when a series starts getting more dramatic.
Think about Dragon Ball. The more serious the situations got, the less screentime Gokuu got fighting. He had to come late to the Saiyan Saga because he had the strength to oneshot Nappa. He didn't even meet Frieza until the final form was already unleashed and had already fucked Vegeta up. In Super, they had to introduce more and more insanely overpowered characters just so he wouldn't curb-stomp them.
This is the type of manga where no one will ever be stronger than Ranna. So if they want serious plotlines, at all, they need to make situations where Ranna's psychlims will make her not do most of the fighting herself.
