Fate centers on conflicts called Holy Grail Wars. In each war, a handful of individuals (Masters) summon legendary heroes—known as Servants—to fight for a powerful wish-granting relic called the Holy Grail. These Servants hail from myth, history, or legend, each bringing unique powers, personalities, and motivations. Battles unfold in modern settings, merging magic with the everyday.

Astolfo is one such Servant, typically in the Rider class. Originating from tales of Charlemagne’s Paladins, he’s known for his bright, impulsive spirit and notably feminine appearance despite being male. Energetic and openhearted, Astolfo keeps morale high, approaches new experiences with childlike wonder, and stands ready to protect allies at any cost.
