Undead Unluck: What Are the UMA & Why Are They So Dangerous?

Undead Unluck is a manga series written and illustrated by Yoshifumi Tozuka, which has been ongoing since January 20, 2020, and has now been collected in 18 volumes as of the time of writing. The story is a supernatural adventure filled with humor, so you can imagine the series will be filled with ridiculous powers and abilities. But, aside from these, the world of Undead Unluck is also filled with various ridiculous creatures, most of which are unified under the name UMA, i.e., Unidentified Mysterious Animals. In this article, we are going to explain what the UMA are and why they are so dangerous in the story of Undead Unluck.

The UMA are strange creatures created by God

Although the human(oid) characters in Undead Unluck represent the gist of the series’ characters, there are also other types of characters present in the series, and the UMA – who are the main topic of this article – are examples of such characters, or creatures, to be more precise, and they definitely deserve some writing about them.

Now, the UMA are very strange creatures. UMA is actually an abbreviation that means Unidentified Mysterious Animals, which is a play on the word UFO and its meaning. They were created personally by God (another name for the character named Sun) in Undead Unluck, and they are actually otherworldly-looking creatures with strange designs.

Some of them actually do resemble animals (although monstrously-looking ones), while others embody monstrous everyday objects or abstract concepts or are simply monsters per se. There doesn’t seem to be a rule as to what they look like, but a lot of them actually do look like the concepts they embody.

And while we’re talking about that, it has to be said that the UMAs actually embody certain rules that have been imposed on the world as a whole. For example, UMA Clothes embodies clothing, UMA Past embodies the history of the world, and so on. This is how they are related to Sun, the character, and through his will, these monsters embody certain specific concepts. Based on what they embody, they can be divided into Phenomenon-based ones (e.g., UMA Snow, UMA Burn, UMA Autumn) and Concept-based ones (e.g., UMA Kindness, UMA Stop, UMA Thirst).

Each UMA has a radius in which its powers are active, and whoever enters that radius will be influenced by the power of the individual UMA. The abilities are unique for each UMA and are related to the phenomenon or concept they embody, so this symbolic aspect is very important in practice.

The UMA are also capable of creating offspring, which is done through enforcing a rule in a very specific way. A notable example is Spoil, who managed to create zombie offspring with his power. If combined with them, they can also become stronger, a phenomenon known as Phase 2. The Union refers to these “babies” as “Juniors.”

The Union usually has to deal with these creatures as part of the Quests they are assigned by Apocalypse, the talking book, and they have to defeat and capture them. Among the UMAs, there are special ones that are called “Master Rules,” which are UMAs that are granted absolute power and can never disappear. One new “Master Rule” is added with each loop of Ragnarok, and since we are now in the 101st loop, it means that there are 100 “Master Rules” as of this moment.
