Discord

 is a weapon in SINoALICE.

Weapon Story
Ever since the "massive, ominous jewel" was excavated from the mine,

people have been inflicted with a strange illness.

It's extremely fatal, and there seems to be no cure.

The illness spread across the land over several months and took the lives of many workers. Those who survived fought over resources and dismissed the tragedy as a natural phenomenon.

The sound of a violin floated over the conflict.

Those who heard its sweet song are said to have stopped fighting.

Dissonance destroys a person's heart.

The musician played as he walked amongst the corpses. The violin and its

"massive jewel" amplified said dissonance.
