Menu Themes

Scattered throughout the spirit world are a number of Menu Themes that players can use to change the look of in-game menus. The selected menu theme will also change the appearance of the YNO website where Collective Unconscious is played. Most notably, a player's username (in the game's text chat) and nameplate (in the game's user list) will be colored according to that player's selected menu theme.

Menu themes can be selected in the 5 tab of the journal in Minnatsuki's Room. Like Book Covers, menu themes are purely cosmetic and have no effect on gameplay.
