Mugenri (无現里, Mugenri) is the primary setting of the Len'en Project games. It's unclear of what the region is, but it's suppose to be a forgotten land that is sealed away from the outside world by the Mugenri Barrier. Yabusame Houlen and their acquaintances are spirited away there by the priest Tsurubami Senri, starting their adventures in this strange land.

The world of Mugenri is based on Gensokyo of the Touhou Project, thus having many similarities.

General Information[edit]

The name "Mugenri" is a wordplay on mugen no en (無限の縁, lit. "limitless relations"), mugen no ri ("illusionary laws"), and Mugenri (无現里, lit. "Unreal Land"). Entrance into and exiting out of the realm is highly restrictive, largely due to the Mugenri Barrier's complexity. The process can be compared to "making a deal" or a "trade".[2] The dimension that Mugenri is located in has rules that allow flight, which is why many of the characters seen are capable of flight, although the specific mechanisms behind flight are not yet revealed.[3] Mugenri is said to be alive[4] and has a soul of its own, although both Yaorochi and Sukune agree that it will never be able to reincarnate.[5]

Geography and People[edit]

The land of Mugenri was sealed away long ago, so it is not well known in the Outside World. Its culture vaguely resembles that of feudal Japan, with a lot of folktale elements added on.

The region mostly appears to only have human and youkai creatures, with rare exceptions such as Kurohebi (and probably Taira no Fumikado). It has been shown that it has a barrier that separates it from the Outside World. It's also known that humans from the Outside World can be spirited away into Mugenri, as shown in Evanescent Existence.

Five major areas of Mugenri are currently known, they are:

While the distances between areas are unknown, it is known that the distance between the Senri Shrine and Devanagara is greater than those from the shrine to the Dragonfly Castle and the length of the Shrine Road taken in Brilliant Pagoda or Haze Castle. While it is known that the Netherworld and Makai exist within Mugenri, not much else is known about the locations. It is also known that a "Spirit World" exists, although it is unclear whether this refers to the Netherworld and, if it doesn't, whether it is within Mugenri in the first place.

Mugenri does not have a unified currency, and what is used depends on the region that you are in. Devanagara is seemingly the most advanced, using coins and banknotes under the modern Japanese yen () system, while the Sanctuary uses the older Japanese mon () currency and system, with Yen starting to catch on as well. However, bartering is accepted as a form of trade all over Mugenri, with alcohol being a popular item to barter with.[6]
Mugenri has its own calendar system called Ruri (流離), which means "exile" or "to wander". It's similar to Japan's old lunisolar calendar, with Mugenri's birth as the starting point of its first era. However, the current year is unknown.
As for religions, while Shintoism and Buddhism are Mugenri's main religions, JynX has stated that at the very least Christianity exists within Mugenri as well.


Little is known about the far past of the world of Mugenri, since more of the characters travelled from far away or were spirited away there. What is known is that the first-generation Shinto priest of the Senri Shrine was the one who created Mugenri,[1] and the second priest of the shrine was the one who introduced the spell card system.[7]

Tsurubami Senri, the current official priest of the Senri Shrine, had tyrannically ruled Mugenri with an iron fist for a long time, oppressing its people and youkai. Because of this, many youkai hide away during the day, fearful of them. Ever since after the events of Evanescent Existence, Tsurubami has not appeared in Mugenri because they are having a holiday in the Outside World, replacing themself with Yabusame Houlen and Tsubakura Enraku to take care of the job of being the youkai exterminators of Mugenri.


Homeologues (同祖体, Dōsōtai, Lit. "Common Ancestor Lifeforms"), a term apparently coined by Tsubakura, refers to similar people across different dimensions, who share several common factors, although not necessarily appearance-wise. Suzumi Kuzu has noted that Mugenri has a lot of homeologues from their perspective, likely having from rewinded time to experience multiple timelines.[8]

Additional Information[edit]

  • According to JynX, the movements of celestial bodies in Mugenri differ from that of "our universe".
  • The famous Hokkaido Japanese breed of cantaloupe, the Yubari King melon, which are a favourite of Tenkai Zuifeng can be found within Mugenri as well.[9]
  • Curiously, the stage 3 theme of Earthen Miraculous Sword, Though the Way Home Is Lost ~ KEEP IN, is modelled after the image of Mugenri itself.[10]
  • It is likely that the "Country of Non-Humans" (人外の国, Jingai no Kuni) that Tsubakura was looking into prior to the events of Evanescent Existence, mentioned in A World That Isn't Fantasy, is in fact Mugenri.
