UN-GO has always been an anime about mysteries, and in this prequel movie we deal with an important one; just how did Shinjuuro and Inga meet, and what were those events we saw in the very first scene of the series? The story does not start with the meeting, but with Shinjuuro's back story. I really appreciated the depth it gave him as a character, shedding some unexpected light on him, and explaining some of his traits which you would have noticed in the main series. Strangely, the film decides to deal with a separate mystery dealing with a religious cult as well as the encounter.Whilst the characters involved all have relevancy to Shinjuuro and the meeting, I thought the mystery was unnecessary, and the time could have been better spent on looking at the events leading up to the fateful encounter. This encounter is the most interesting and important part of this entry, as it develops the relationship between Shinjuuro and the members of the travelling group of singers, in particular Yuuko, who is of painful significance.

Despite the fact I said the time could have been better spent, the mystery isn't bad (although if you've watched the series you'll know what's going on from the very start) and it is does give some context to the relationship between Inga and Shinjuuro and the deal they have. Because of our prior knowledge of Bentenmaru there is no mystery for us which is a little disappointing, but the way Shinjuuro solves the mystery is still interesting, and the climax had a lot of tension. So although I dislike the side plot being there in the first place, at least it was executed well.

Despite the fact this is marketed as a film, it is more of a double length episode, so don't go expecting a massive improvement in the art or a whole new soundtrack. A movie level budget would have been nice, but given the already high production quality of Production IG, it isn't much of a comprimise.

UN-GO episode:0 Inga-ron is enjoyable and has a lot of intrigue, and is a must watch if you have watched the original series; the mystery was decent and it did a good job of explaining and revealing things regarding the original series. It also gives quite an amusing look at some of the characters of the original series before they knew each other properly, which brought a smile to my face at several points. It could have been better, but it was still a solid movie that should be watched.
