ASSASSIN'S CREED⑨
Ubisoft Gensokyo studio news release!（Just kidding）
Backstory: This time the stage has shifted to Gensokyo and reveals the life story of the strongest fairy assassin Cirno.
The straggle between Assassins and Templars also exists in Gensokyo. Hakurei Reimu and her four follow Templars plot to acquire Bad Apple, a relic that has the power to rule over Gensokyo, and rampage around under the name of "incident resolution".
In their outrage, Cirno's friend, Daiyousei of the Misty Lake, was murdered.
To avenge her friend and put a stop to the Templars' bloodshed, Cirno joins the Gensokyo chapter of the Brotherhood and fights the Templars with the help of the great inventor Kawashiro Nitori.
When guards discover the bodies Cirno left, they always scream "Hey, ⑨!"
And so she takes this as her nickname, the strongest assassin "Eijiǔ" (Ezio).
Sorry I cannot make this up any further.
