Mail follows a paranormal detective and occult specialist Akiba as he finds himself investigating lost souls. His primary purpose is to give these souls a proper send off so that they can enter the cycle of reincarnation or simply be damned for eternity. Each chapter is stand alone in its story telling though in the later half of the series we are given a bit more lore so to speak and Akiba is given a sidekick and his background is explored more thoroughly though I suppose thoroughly is a pretty generous term here given each instance of this is rather brief though satisfying. Each chapter begins the same way and ends the same way though each time there is slight deviation and changes suited for the story at hand in each chapter. The author has a very good way of telling you just enough to keep you interestedthis sounds like an insult as if hes doing the bare minimum but I assure you its not. So little is said but the story is so satisfying to read it executes just what it wants to do very well. Its very succinct and its better off for that. This story is kind of unique in the regard that it is exactly what you would expect from it and it doesnt ever deviate from that narrative. Its about a dude who does exorcisms and always arrives just in time to save the soul and the person being haunted. I think the art is much like the story telling very basic but so intrinsic and detailed but beautiful. There really isnt anything special at all about the style but its just so charming and compliments the story so well. I think that if the story telling was slightly different or perhaps the art was done by someone else this series just wouldnt work at all. It just seems so right? I dont really know how to put it but I just like it a lot it isnt the best thing in the world or anything but I was just very satisfied by what I read. Atmosphere art writing the settings the people the lore the set ups it was all just very solid and I think its the perfect example of all of these things that arent all that impressive in their own right building up a very satisfactory story. I feel like the ending was rather abrupt it leaves a lot of things left neglected that I feel like were going to be touched on. Like more about the society of priestly detectives as well as the companionship of Akiba and you know who. I hope that the Corpse Delivery Service delivered on that but from what it seems this was a very nice story cut short hence the addition of a sidekick before the abrupt end. All of that said and done though I really did enjoy this and I would recommend it to anyone into horror manga and light mystery as well as episodic stories
