Also known as October 20th. Apparently, this is the day when a major part of Twitter decided to change their profile pictures to a random picture of Shirou Emiya. Caused by a person who is a friend with another person who used the same profile picture, then changed to another. Then, they decided to try and succeed in using the Shirou profile picture, knowing it was too much power to handle. A massive wave of hero of justice energy affected any affiliated Twitter user, having them change to a Shirou profile picture as well. It proceeded to become a massive chain of users adopting Shirou profile pictures, and eventually, an army of heroes of justice was made.
