Shinji Matou states, "Have you been inside of the Arena yet? Interesting place, isn't it? I thought it was amazing at first, but it's really pretty primitive. It's like an ocean pulled from a story. I even saw a Master who managed to summon Armstrong. Sorry, I was just messing with you. I dig the sea theme. Overall the game's pretty well done."
Fate/EXTRA Last Encore
