EMIYA Shirou's Self-Centered Holy Grail War

Cornered by Lancer, in desperation, Emiya Shirou ends up summoning Archer EMIYA. And naturally, upon seeing his chance, EMIYA takes full advantage to kill his younger self over and over again, until he's satisfied. However, upon seeing the futility of his attempts, he decides to stop for the moment. At least, until the proper chance to kill Shirou for good finally presents itself.
