Désir Lyrics - Fate/Apocrypha

Désir Lyrics - Fate/Apocrypha belongs to the anime Fate/Apocrypha, take a look at the argument:

The Holy Grail, a transcendent and coveted relic, holds unimaginable power capable of fulfilling any heartfelt desire. To seize this profound force, a select group of magi, known as "masters," summon legendary Heroic Spirits, referred to as "servants," into a momentous clash called the Holy Grail War. Only through this perilous battle royale can the last master and servant standing claim the Holy Grail as their own. Unfortunately, the third Holy Grail War ended inconclusively, shrouding the whereabouts of the Grail in profound mystery.
After countless years, the enigmatic magi clan Yggdmillennia boldly proclaims its possession of the Holy Grail, subsequently severing ties with the esteemed Mage's Association. Responding to this audacious declaration, the Association dispatches a team of 50 elite magi to retrieve the Grail. Tragically, all but one valiant individual succumb to an unidentified, formidable servant. The lone survivor is then employed as a messenger to convey the resolute message from Yggdmillennia: war has been declared upon the Mage's Association.
In this singularly gripping conflict with just two factions involved, the Holy Grail War adopts an unprecedented form. Both Yggdmillennia and the Mage's Association marshal their forces, each consisting of seven master-servant pairs. The side that tragically loses all their combatants first shall relinquish their claim to the precious artifact. As the 14 acclaimed masters summon their extraordinary servants and converge on the battlefield, the mystical realm trembles with anticipation, bearing witness to the triumphant emergence of the Great Holy Grail War.
