Oh, hey, it's the manga version of the second half of the third OVA. Damn, really running out of those anime adaptations of manga chapters, aren't we?
And I remember when I watched this, I wondered why the hell Ruri didn't double-check that a geyser wasn't under where the clothes bundle was sitting before she secured it together.
And Marika continues to disturb me with her expressions and behavior in general. There's just something seriously twisted with that girl.
I don't really blame her that much for final smashing him out of there, though, unlike another commenter. It's a high-stress situation and she lost her cool in the only way it can be expected at this point for a tsundere. This is also an extra story, so it's not like this is meant to be reflective of anything all that canon, anyway. It shouldn't be taken all that seriously.
