I was hoping that they abridged that part, where he buys isekai viagra... but eh, the whole ED arc was the author writing himself in a corner, writing a horny-as-fuck protag and trying to prevent him from fucking everything that moves.
Although to be honest I loved the episode. Ariel was big here - she's clearly furthering her own agenda, but doing it in a transparent way, while helping the ones that she cares about to further their own goals. In a single stroke she helped a friend and got a powerful ally.
