This is the most debated piece of evidence in the conspiracy. During Pain’s invasion, Tsunade summoned Katsuyu to protect citizens and heal wounded shinobi. She then expended her Byakugou no Jutsu (Strength of a Hundred Seal) to save the entire village.
I notice the phrase — this seems to reference Tsunade from Naruto combined with gaming slang “sus” (short for “suspicious,” popularized by Among Us ).
Tsunade owned a necklace that belonged to the First Hokage, which was said to be worth enough to buy three mountains. But it gained a "sus" reputation because everyone who wore it—other than Tsunade—ended up dead.
"Because when he hears that, he'll know I'm serious. And when I'm serious, people end up in the hospital." She smiled, and it was the most terrifying thing any of them had ever seen. "Now, let's go find out who has been living a lie in my office. Because somebody... is sus."
She turned, her eyes blazing. "Someone is in my head, Shizune. Or close to it. They have my memories, my mannerisms, my gambling debts... but not my taste in sake, not my efficiency with village funds, and certainly not my ability to crush a man's skull with two fingers for questioning my judgment."
"Naruto is an unreliable witness," Tsunade declared. "He thinks ramen is a food group. He probably saw a training exercise. A very shiny, rhythmic training exercise."
