Fanon:Quietus of Tricou

The Tricou; a family so rarely regarded and even forgotten by many, few people query their death. The demise of this family is mysterious, and its background, even more mysterious. I've been pondering about their deaths for sometime, and with information I acquired from this wikia, this fanon will reveal the true story of their doom. Stay in tune.

Background
According to the Tricou Family's wikia page, at the beginning of the story they're rich. However, many of the story elements (relationships, order in which the Tricou are killed, etc.) will contradict to the family's actual memories.
