Chapter 47: Challenging the Demon King
"What?! I literally neutralized the enemy without killing them and eliminated a man-eating monster."
Sanguinius didn't appreciate Faker's decision, the individual he suspects of being EMIYA Shirou.
A man filled with good intentions, who unfortunately didn't have a... heroic ending.
Why this assumption?
The quest description literally describes an altruistic and tragic hero.
He only knows one person combining the trait of a Faker and a tragic hero.
[The no-divine seat "Faker" finds your methods too similar to his own.]
[He specifies that you choose efficiency at the expense of heart.]
Involuntarily, Sanguinius was left speechless by Archer Emiya's words.
Deep down, he knew his methods had become increasingly warlike.
He had promised efficiency over the subtleties of "acceptance."
