Hmm.. no (legal) romantic relationship between Kanba and Masako? That's a bit of a shame. The OP suddenly makes sense now, with each of the three penguins standing separately, but the black one siding much closer with #1.

And then we've got the bandaid on #1 as well..

The doctor's been very good about playing with words to bend their meaning yet remain truthful - but did he at any point promise that the medication would save Himari? If he did.. that's a pretty big breach there.

I can't remember the surnames of everybody, but is it possible for our pink haired friend to be Kanba's biological father?

I wouldn't say I totally dislike the new direction of the show, but we've all but completely diverged from our original goal of obtaining the Penguin Drum now. Medicine aside, wasn't that supposed to be the all-powerful cure for Himari? This show took a pretty hard left around the middle and turned itself from a survival show to one about people with dead/shitty parents/caretakers.
