Those ghosts are lucky Nanika didn't eat their ectoplasm.
That's so boring...Yeah...Sorry about Nanika.Nanika, we're going home.That cat-like thing was scary.So that black mist was Nanika-chan.Okay, let's go home.I'm scared it might come again, so let's move on to the next life.Thank goodness it wasn't a ghost...Mmm... I don't know.By the way, I wonder why Nanika-chan was here.
