This show is thoroughly inoffensive. It has a good opening, its female characters are fairly cute and charming, and it has a main character that loves pharmaceuticals, much like one of my favorite manga, Akagami no Shirayukihime.
But unlike one of my favorites, which features politics, conflicts of interest, intriguing events and goals, and well written, complex characters... this show seems wholeheartedly dedicated to being about as bland as imaginable.
The prime offenders are in the secondary cast. The protagonist herself seeks out interesting things fairly often and is comprehensible, and is about as flavorless as a protagonist might be expected to be. However, every person she comes across is more tasteless than the last. The other summon, Aira, is placed in a perfect position for excellent storytelling, but she is completely marginalized in the show. The love interest for Sei, commander Hawke, is possibly more bland than prince charming himself, a tool to tell the wilting love story the main character needs to use her powers. The institute's director is the most interesting character in terms of complex motivations plays a sort of guardian role for Sei, but even he fades over time as she leans on the commander more and more.
As for the rest... it's safe, and totally forgettable. Somehow making potions and learning magic is instantaneously boring. They just put leaves in water and boil it and put magic in it. The topic that Sei cares most about is simmered down to the complete bare minimum by the writers, lending precisely zero intrigue to the objectives she seeks out every episode, both as an alchemist and even as the saint.
Don't bother. If you want to fall asleep watching an anime, this one might be the ticket. Otherwise, I would say that even the overused isekai genre tag is wasted on this show.
