The World Language ｢世界の言葉, sekai no kotoba｣ also known as the Voice of the World ｢世界の声, sekai no koe｣ is a natural phenomenon that announces important events.
Functions[]
When certain phenomenon occur — such as the acquisition of skills, racial evolution, the obtainment of a demon lord seed or hero's egg, the awakening of a demon lord or chosen hero, and the activation of some skills — the World Language will echo within the consciousness of all related parties. Sometimes it is heard by a single individual, while in other instances it is broadcasted to a large group of individuals within the range of the source phenomenon.
Skills also have a built-in functionality that allows for the utilization of the World Language, resulting in Yes/No prompts being given to their users in relation to the skill’s activation. This was taken advantage of and hijacked by Ciel in their days as part of the Great Sage, acting as a means to properly communicate with Rimuru Tempest in response to Rimuru's desires for companionship.
Properties[]
The World Language is a phenomenon present in all places, even in material worlds without magic such as Earth or isolated dimensions like the inside of Infinity Prison. Those who hear the World Language are also capable of understanding its meaning as if it were spoken in their native tongue.
