I never watched the show since it didn't seem to be important or action like in the route, but as I was waiting for Steins;Gate latest episode. I saw the show's episode 8 and said to myself, why not watch it while I'm waiting since it's just half a regular episode anyways. Finished watching episode 8 and I must say: Tohsaka still got those curves and the animation is so smooth even though it it's not an action Fate. And I noticed something about the whole episode... it was awfully similar to Fate Hollow Ataraxia day events... and boom , it hit me. Is this show secretly and possibly Fate Hollow Ataraxia, because it would make sense if characters that were supposed to be dead are alive and I also saw the pool episode which reminded of that pool event from the visual novel as well in Fate HA! I'm going to start watching it again from Episode 1 to see if the similarities are a miss or hit.
