Karma_198
Good author of the chapter, and this Issei, along with his Kantusa, and Boosted Gear (not to mention that this line of Fate is an AU), he managed to summon with 100% certainty two servants: Altria (Demon Sword + Dragon Power) and Artoria (for the same reason). It would be quite interesting the reactions of Gilgamesh, and this Shirou, as they would act like Scott and Logan, when they disputed for the love of Jean Grey.
