the only thing these trials showed me so far is that the priestess has a good nose and that MC has enough ability so far to take care of and remain successful regardless of carrying around a burden. Bet she'll still get in the way somewhere down the line.
The dude can fight, use magic AND heal... what would he need her for? That's clearly the path of the solo player... obviously shes just foil and fanservice material... who didn't think how is her underwear to be able to use that dress? If she is using it... and I can't even begin to imagine how uncomfortable her and that goddess clothes are... just the risk of a boobflash would keep her on alert all the time... that's in no way a priestess nor a fighters clothes... man's fantasy of women's clothing is downright ridiculous... (╯°Д °)╯╧╧
Those trials are exactly why romance and harem ficks up most fantasy stories... liking or not those women end up as a burden cuz they don't know how to make relationships between equals... ┑(￣Д ￣)┍
