Lancer is a is a fierce but balanced warrior who enjoys combating a worthy opponent. He has a playful attitude and takes a very carefree approach to life, but is quick to work himself into a frenzy during a heated battle. Lancers are hailed as the "Most Agile" of Servant classes.

He is quite amiable, chatting with many of the former Holy Grail War participants, and is well liked. He makes no attempt to combat the Shadow Wolf Beasts during the Fuyuki eclipse, instead quietly presiding over Avenger's ascent into Heaven's Feel from a distance.
