Why Yuuka? Mima is being nice and keep Cirno on her seat so she won't bother you, you jelly? But really, that's kinda unnecessary there, Mima. Thank god she didn't do anything else.
She is a spirit, so she might be less affected by a punch than normal (and makes it more plausable for that effect to happen)
Or she's just Mima and a punch coming from Yuuka is nothing for her.
Oh, which reminds me...Hey.Treated Them Well!I treated them to snacks and juices in your place.Okay!Yes, it has!You evil spirits are just plain awful!She is your partner after all, one way or another.I met that ice fairy on the way here.Don't tell me that you-...Quit worrying!...and persuaded them to go back to their seats.Episode 988: That was quite considerate, wasn't it?From the Artist's Pixiv page.Here's a souvenir, the Ray Stinger.Mima...Okay, good girls.Then I told them "Yuuka's busy right now, so bother her later"...Has my face turned into something out of manga?
