The Story of Emiya Shirou from a Parallel World

An inexplicable sense of fear spread through people's hearts.

The information Aizen had revealed, and everything it implied, made people tremble.

At that moment, many felt that reality had become incomparably illusory and false, sending them into an existential crisis.
