Gotta love the way they put Okarun's ball back is by playing ball xD.
Beyond that, the series gets back what it does best and banter, this time between Momo & Aira. She is determined to exorcise Momo, but clearly has developed feelings for Okarun. With that said, I don't know if I should laugh or feel sorry for her for getting relationship advice from her dad's porn collection.
To add on top we got the classic troupe of guy falling on top of girl misunderstanding. Okarun had good intentions since he wanted to just work out, but Aira got in the way. On the one hand, it would have been better for him to be honest with her. Though I would imagine she just cares about hanging out with him less about what they are doing. We're already banging with another incident with the Aliens and this time Momo & Okarun are separated with Okarun being with Aira. The transformation sequence for Aira was great and given that the aliens said that only high spiritual density individuals should be able to enter the void space.
