Strength of a Hundred Sealings Technique was Tsunade's exclusive secret technique, personally taught to her by Uchiha Gin after she successfully cultivated the Yin Seal. It was meant to make up for her lack of a signature killing move.
Combined with the Creation Rebirth Technique she had practiced for years, entering the Strength of a Hundred state would qualitatively enhance both her self-healing ability and ninjutsu. She could even hold her own when sparring against Jiraiya and Orochimaru in Sage Mode.
When black Cursed Scripts completely intertwined across Tsunade's fair skin, streams of almost tangible blue Chakra burst from her body. The terrifying aura radiating from her drew everyone's attention.
"That's... Karma?"
Jigen, who had been overseeing the battle, was drawn by Tsunade's soaring presence. He turned his head, and upon seeing those familiar black markings, his ripple-patterned eyes narrowed slightly.
That unique form was clearly the state an Otsutsuki Clan Vessel entered after being activated. Could this human also be a Vessel left behind by Kaguya?
Remembering Curly, whom he had encountered in the Wind Country years ago, Jigen's brows first furrowed, then relaxed. He realized that the aura radiating from Tsunade in the distance did not possess the fluctuation he recognized.
"Hmph. A clumsy imitation."
That state resembling a released Karma merely had the appearance of one. It had given him quite a scare for nothing.
Still, Jigen was curious how powerful this technique, created by a human imitating the gods, truly was.
Unaware that she had drawn attention, Tsunade was currently clenching her black-marked delicate fist with a regretful expression.
"Ah, what a shame."
What she regretted most now was not storing more Chakra in her Yin Seal. Otherwise, the Strength of a Hundred Sealings Technique might have been even more powerful. But it was too late
