Its a bit of a drag at first being an episodic show. Each episode deals with Fumika our protagonist delivering the titular shigofumi to someone. The episodes will typically deal with the circumstances around that shigofumi are after all letters from the dead. However with each episode there are slight plot teases which work to build up the idea that something is going to happen. The mystery is introduced fairly on and mentioned in the AniList synopsis: Fumika is the only Shigofumi postman who ages. I think this is first brought up in episode 2. Guesses can be made at why around episode 5 or so and its outright stated in episode 8 or so. However the mystery Id say is only one small part of the show and its appeal. Once the mystery is solved the viewers investment shifts immediately to all the circumstances around it. The series really kicks it into overdrive in the second half with all the plot teases finally coming together to form something strong and coherent. I went from taking the series somewhat casually to actually deeply enjoying it in the second half. The plot progression and the fallout so to speak of said progression was a lot of fun to follow and really elevated the series from that point forward. One thing that I really appreciated was that the series turned out to be something different than I expected. While it wasnt a complete tonal shift like something such as meta it definitely went in a direction that appealed to my personal tastes. The feeling was more akin to not caring all that much about something because of the perception it gives off and then being pleasantly surprised when it catches you off guard. Shigofumis characters are fairly solid. While theyre not strong enough to be the driving force behind the show they certainly arent weak enough to drag it down either. Fumika has a certain attitude that makes one go ugh of course at first which shifts to an oh I see as the story plays out. Her talking staff Kanaka and the running gag of her desire to be human is a humourous pleasant distraction from some of the more somber tones and themes of Shigofumi. Conclusively I dont think that Shigofumi really does anything outstanding. Theres nothing awe inspiring or breathtaking about the series. Conversely however it achieves what it sets out to do and it does it well. Rather than the feeling of having stumbled upon a new favourite Shigofumi leaves the viewer with a feeling of satisfaction. It invokes that happy sigh that comes after finishing a great novel theres no need to spread it around nothing in your life has changed but at the same time youre still glad you did it.
