Yuuri recognizes Fatcatfish as the one who murdered her family, apparently he murdered her parents and her younger sister. That is why she goes crazy and tries killing him.
Her sister's name is Mei.
Anyway her Dad was in the same Anti-Mafia division that Yuuri is currenttly in. At 10 years old, Yuuri went to visit her family and that is when the murder of her parents and Mei happened.
