Reality Codes

From HoYoverse Multiverse Index

Realities, characters and worlds can be identified with the help of reality codes. These follow a standardised format.

Reality codes and nicknames are made by fans, and not official miHoYo lore. It's main purpose is to help us sort the characters and distinguish between different versions, whilst recognising they're related. The codes are not representative of any sort of clear cut indexing system miHoYo uses for their stories.


The first game or related medium the reality was a part of.


Identifying Trait: A letter code pointing to a trait that allows you to identify the reality. For instance: In a reality characterised by the romance of the three kingdoms, the code is 3K.

By necessity, these may be extended. For example, if Chloé's Theater is CT, and Houkai Gakuen 4-Koma's mainline is 4K, then a version of Chloé's Theater in the 4-Koma may be written as 4KCT.

Era: When a world has multiple eras, the era is denoted by number. The base number is 0. If an era is identified before 0, there will be a minus placed after the number. A number only needs to be included if multiple eras are identified.

Extra letter

If two realities are extremely similar, but still in some way different, you may use a single added letter to denote them being separate. Example: B3-3K-A and B3-3K-B

Nested realities are shown with a slash. Realities can be given a nickname to identify them.

If a character's reality of origin is unknown, then their associated reality will be used to identify them.
Alternatively, they may be registered as (Unknown)

Reality codes pertaining to real life organisations or staff members related to miHoYo do not need to be included. Instead, if they have different iterations, those may be included on their page.
