the Earth vacation episode and a much needed breather. Seina back home surrounded by his family is charming precisely because you see how much has changed from his perspective while everything at home is exactly the same. the comedy of his family being completely unfazed by whatever chaos follows him is very funny and the warmth of the home setting provides a genuine emotional anchor. the girls visiting Earth and reacting to normal human domestic life creates great fish-out-of-water comedy without being condescending about it.
