Assassination of Cuphead

"Oh no. Trịnh Thị Kim Chánh just made her evil move. A horrible move. Just as Cuphead will die someday... well, not at old age, but only within a matter of weeks or days or earlier, only at young age. Now she's gonna kill him and put us into a bad morale. I have a bad feelin' about this. She'll be reducing him into ceramic shards right now. Without Cuphead, Inkwell Isle's doomed for this, but I hope it's all up to Mugman to avenge his bro now. So, I think the ARVN's responsible for all of their evil intentions now. Even worse than the USRAC. Seriously."

--Su Ji-Hoon, The Cup Shard
