I know you must be thinking it's a bit early to review a show that only has 5 episodes out at the moment, but I think it is a work of art. Usually in iseki shows the protagonist (main character) is fighting with a sword or magic, but in this show it's not like that. Sei (the main character) isn't even on the battle field, and I kind of love that cause it kind of explores what an iseki anime might be like if the protagonist never went into battle. Sei, is instead enjoying her life at a institute that makes potions outof herbs. This show in my opinion is so far the best anime of the season.
