Mii Cast

The Mii Cast (Japanese: 配役Mii図鑑 Haiyaku Mii Zukan; Mii Cast Encyclopedia) is a Journal catalogue of non-playable characters in Miitopia. The player can recast any role already unlocked from this menu with the exception of the Dark Curse, which requires defeating the Darker Lord and picking the "Save him" option again.

Description
Miitopia offers 45 roles, not counting the Travelers' Hub visitors, that Mii characters can be cast as. Roles range from plot-related individuals to mere town residents. To unlock a role to be recast, the player has to already have assigned a Mii to it at least once. Non-playable characters of significance in the story like the Dark Lord, the Royal Court, etc. require input from the player in both the Nintendo 3DS and the Nintendo Switch versions. In the Nintendo 3DS version, for smaller roles like the travelers (for example, the Roving Photographer) and town residents, when they appear for the first time, the game will automatically populate the roles using either the preset "world Mii characters" or, if the player's Nintendo 3DS has SpotPass activated and is connected to the internet, random Mii characters uploaded by other players. In the Nintendo Switch version, the player has to manually cast them like with the major story characters, though the Travelers' Hub visitors retain the automatic casting using either the preset Mii characters, the player's Mii bank as long as the Mii characters are not cast in any role yet, or Mii characters from the Nintendo 3DS version's online database via enabling the "Popular" setting on the "Mii characters" menu on the title screen (requires Nintendo Switch Online subscription).

Casting or recasting roles can be done either one by one or, if the roles are grouped in a category, simultaneously. The steps for casting are as follows:
 * 1) Open the X button menu, then go to Records > Journal > Mii Cast. This step is only applicable for recasting.
 * 2) Pick an individual role that the player wanted to change.
 * 3) Select a Mii to take the role. The Nintendo Switch version requires Nintendo Switch Online subscription to use Mii characters from online sources. Aside from creating from scratch or selecting from the player's system or Friend's Mii list, the Nintendo 3DS version also supports Tomodachi Life save file, Autoassign, and QR codes for deciding Mii characters. Other methods specific to this version include:
 * 4) Mii Central: The player may download a Mii stored in the Mii Central server through SpotPass.
 * 5) Search: The player may search for a Mii uploaded on the internet by name.
 * 6) Confirm the Mii's name. This step does not apply in the Nintendo Switch version.

In the Nintendo 3DS version, the Autoassign option is available if the player has SpotPass activated and connected to the internet. This allows the player to switch the role's Mii into any random Mii uploaded online depending on other players' casting data and player votes from the questionnaire. In the Nintendo Switch version, the option to use Mii characters from outside the player's system is done through the "Receive all Mii characters" button, which requires Nintendo Switch Online subscription. Certain roles like the Dark Lord have an option called "Default" when casting them for the first time. This automatically sets the Mii to the default Mii defined by the game, so for example, the Dark Lord will be cast with a male Mii named Stan if "Default" is used.

Certain roles can also end up having their faces stolen and attached to boss monsters. Monsters with these characters' faces can be re-viewed in the Journal. Changing the corresponding Mii via Mii Cast will also change the monster's face on the Journal. However, this cannot be overwritten by encountering the similar monster bearing the face of a Travelers' Hub visitor or his/her friend.

In the Nintendo Switch version, it is possible to delete a Mii already cast in a role. This is done via the "Mii characters" menu and deleting that Mii there. Doing this results in a default Mii being used in his/her place. This is the only way to see the Dark Curse's default Mii (a male default Mii named "Mii") as there is no "Default" option for him.

Also, in the Nintendo Switch version, an individual Mii can only occupy one role, including as a party member. If the player attempts to use the same Mii for another role, the game will warn the player of this and will create a duplicate of the Mii if the player proceeds anyway and there is still enough space in the player's Mii bank.
