After Tsunade and the others entered the Flame Mountains, they sensed that something was wrong, but Hinata used her Tenseigan to check their surroundings for anything unusual. Tsunade frowned. "That can't be right. Ever since we entered the Flame Mountains, I've felt like someone was watching us, but the White Eye hasn't detected anything. How strange."
Although Tsunade was not a sensory ninja, she did have some Uzumaki blood. The Uzumaki Clan's senses far surpassed those of ordinary people, so she had always trusted her instincts.

Tsunade shook her head. "Impossible. My instincts have always been accurate."
"But Hinata hasn't found anyone watching us," Rin said, puzzled.
