Illya loves her family. Everyone in the Emiya Household was precious to her and she'd do anything to be with them longer. However, that wasn't something that her dying body would allow. So instead, Illyasviel's last wish was to at least play a certain game with Shirou, Sakura, and Rin – her favorite game – Elder Tale... So why are they waking up in the ruined streets of Akihabara?

To a soldier, death is the end. Though, to a certain someone, that's just an excuse for him to do whatever he wants with them. And for that, those soldiers start their new adventures in a completely different plane of existence: Gensokyo.

Several of the girls from Gensokyo find themselves in what appears to be the outside world, but since when is the outside full of costumed superheroes and supervillains? This is the story I've been building up all this time.
