Well i found this chapter a bit more enjoyable than the previous ones since it did have A-tan (although in her current form she is pretty much as useful as Nagi).
Of course A-tan would be able to see the father, even with powers sealed....its freaking Athena! \o/
Other than that another week wasted for this manga, I would rate this chapter 3/5 but im so helplessly biased towards athena that i'll be generous and give it 4. Seriously Hata, get your shit together.
