Prologue
As the weakest master in the Holy Grail War, Hiroshi struggles to control mana, the magical energy necessary to summon and sustain his servant. His ineptitude with command seals, the magical tattoos that allow masters to exert control over their servants, further compounds his challenges.The Holy Grail War unfolds in the Royal City, a mysterious and grand location where the fate of the participants will be decided. Traditionally, seven servants are summoned at the outset of the war, each representing a different class of heroic spirit. However, the rules allow for additional servants to be summoned if the master possesses sufficient mana reserves.
