What Is Onibi? Japanese Ghost Fire & Nioh 2 Explained

Have you ever encountered a mysterious floating flame while playing Nioh 2 and wondered what it was? That eerie little flame is called Onibi, a supernatural fire that has appeared in Japanese folklore for centuries.

Although Onibi is often associated with the spirits of the dead and other mysterious phenomena, its appearance and interpretation have varied across sources and regions. In Nioh 2, Onibi is reimagined as an elemental yokai that attacks the player, giving this traditional mysterious fire a very different role.

In this article, we’ll explore what Onibi is, how it has been described in Japanese folklore, and how Nioh 2 brings this mysterious yokai into the world of video games.

What Is Onibi?

Onibi is a mysterious fire or light found in Japanese folklore. It is often described as a bluish or bluish-white flame that appears at night. It is traditionally associated with places such as graveyards and other dark, isolated areas. However, its appearance and interpretation have varied across sources and regions.

Onibi in Japanese Folklore

Legends of Onibi can be found throughout Japan, but they vary considerably from one region to another. Some describe Onibi as bluish-white flames appearing near graves, while others portray them quite differently.

For example, one folktale from Yamagata Prefecture describes Onibi as a bluish-white flame that appeared near graves on rainy summer nights. However, another old account describes Onibi as something that looked like fire but was not actually fire.

Traditional accounts also do not always clearly distinguish Onibi from other mysterious lights, such as Kitsunebi (fox fire). As a result, the boundaries between these supernatural phenomena are not always clear.

Regional Legends

Stories about Onibi have been passed down throughout Japan, but their details are not always the same. Some accounts describe a bluish flame near graves, while others portray Onibi in different ways. These regional variations make it difficult to give Onibi a single, universal description.

Onibi and Other Mysterious Lights

Traditional accounts do not always clearly distinguish Onibi from other mysterious lights, such as Kitsunebi.

As a result, the boundaries between these supernatural phenomena are not always clear.

Another Meaning of “Onibi”

Interestingly, the word “Onibi” does not always refer to a mysterious supernatural fire.

In parts of Kyushu, “Onibi” or “Onibitaki” is the name of a traditional fire festival held around the New Year.

How Has Onibi Been Explained?

For centuries, people have offered different explanations for Onibi. Some believed it was connected to the spirits of the dead, while others regarded it as a mysterious supernatural phenomenon. Today, some reports of mysterious lights may be explained by natural phenomena, although no single explanation accounts for every traditional account of Onibi.

Spirits of the Dead

One of the most common traditional beliefs was that Onibi was connected to the spirits of the dead.

According to some accounts, these mysterious lights were thought to appear near graves or places associated with death.

Supernatural Explanations

Not every traditional explanation connected Onibi with human spirits. Some stories simply treated it as one of many mysterious supernatural phenomena.

Natural Explanations

Some modern explanations suggest that reports of mysterious lights may be related to natural phenomena, such as gases produced by decaying organic matter or atmospheric and optical effects.

Onibi in Nioh 2

In Nioh 2, Onibi appear in different elemental forms, including fire, water, and lightning. They can attack the player with elemental abilities, making them more than just mysterious floating flames. Inspired by traditional Japanese folklore, these in-game Onibi are designed to create fast-paced and strategic combat encounters. Rather than simply appearing as mysterious lights, they actively attack the player, making them memorable enemies despite their small size.

Inspired by Folklore, Reimagined for Gameplay

Traditional Onibi is usually described as a mysterious supernatural flame, but Nioh 2 reimagines it as an enemy that directly challenges the player. Although the design takes inspiration from Japanese folklore, its combat abilities and aggressive behavior were adapted to suit the game’s action-focused gameplay.

Fighting Onibi

Although Onibi is not one of the strongest yokai in Nioh 2, it can quickly become troublesome if ignored. Because it can attack the player with elemental abilities, it is often worth dealing with before focusing on larger enemies.

My Experience

Personally, I usually defeat Onibi with arrows rather than cannon fire. Since Onibi is a relatively small enemy, I’d rather save my cannon ammunition for larger and more dangerous opponents.

Final Thoughts about Onibi

Although Onibi is often portrayed as a frightening supernatural flame, its meaning has changed across different regions, traditions, and even modern video games. From mysterious folklore to action games like Nioh 2, Onibi continues to capture people’s imagination and offers a fascinating glimpse into Japan’s rich cultural heritage.

If you first encountered Onibi through Nioh 2, I hope this article has given you a glimpse into the fascinating folklore behind this mysterious yokai.
