Chapter 7:
In the current Senju clan, even though the First Hokage has passed away, both parents of the Tsunade are still alive.
Moreover, Tsunade's younger brother, Nawaki, hasn't even been born yet!
Therefore, Tsunade isn't burdened by the pessimism or sadness that will later characterize her. Instead, she's just a lively, cheerful little girl who already has a love for gambling and a bit of a violent streak!
Orochimaru, calm as ever, responded to her presence with, "It's just unexpected. Come in and sit down if you want."
After saying that, he turned back to his living room, nonchalantly playing with his ninja tools, paying her little mind.
Tsunade, not at all bothered by Orochimaru's indifferent attitude, strolled in, her hands clasped behind her back, her little feet tapping lightly as she walked. But midway into the room, she stopped and wrinkled her nose.
"Hey, Orochimaru, why does your living room smell so bad? Didn't you always like to keep things clean?"
"A stray cat got in just now," Orochimaru lied smoothly, then walked to the side and opened the window to let the room air out.
He knew that what Tsunade was smelling was actually the lingering odor from the impurities his body had expelled after drinking the gene enhancing serum.
