Asobi ni ikuyo!

When they first released this anime on Crunchyroll more than a decade ago, I recall being blown away by the animation and character designs of cast and it still does that...for the first several episodes until it appears the budget dried up and obvious long pans, stills, and recycling rear their ugly heads.

The animation quality tanking and money-saving measures is a damn shame because the show works when it's at its horniest - beautiful and painstaking in the nude scenes of the early episodes.

All the usual suspects appear: cat ears, huge milkers, plug suits, food-closeups, cig-smoking scientist, fast-food chomping American, gun porn, glamours car chases, etc. Sadly, even the fan service fades by later episodes which means the series has to lean on the played out harem tropes of a mediocre MC and his crew of hopelessly infatuated love interests, incredibly low stakes, and surprising lack of laughs or chemistry among the cast other than between Aoi and Manami.

If you're into standard harem, checkout the fan service of the first three and last episode, and outro animation.
