The story starts as Sei Takanashi is isekai'd to kingdom of Slantania. She overhears that the Grand Magus summoned two saints, the prince declares the other girl as the Saint. She decides to stay at the Research Institute to learn herbs and potions.
The plot is basic and predictable, there are no antagonists or shocking events in the story. Sei does magic so effortlessly, you know what's coming next. It lacks a more detailed and engaging plot because similar things happen during the series. That being said, it's still a enjoyable, lighthearted watch. The art and opening is good.
If you like feel good, easy to watch anime with isekai, shoujo and romance, you might enjoy this!
