normally u shudnt buy 2 shots, but shes a trader role that specializes in making money. i could easily see her having a passive that allows her to buy an item twice, or simply buy one last night and one today
none else nearly had enough gold to buy it, and its not only the buying that's incriminating, its the fact that both shots were super. if someone else bought the item and used it, it wud appear as kagura doing the super kill and someone else doing a regular kill
