Chapter 137 : Practicing the Flying Thunder God Technique!!
"Genya-sama, does the Yin Seal mark have to be on the forehead?"
Senju Hikari frowned slightly. The technique of the Yin Seal would leave a crystalline mark on the forehead once practiced, making it extremely noticeable.
"Can this Yin Seal mark be hidden?" Genya frowned as well. If it couldn't be concealed, they'd have to resort to wearing a headband or something similar. If they were ninja, they could just use a forehead protector.
"I'm not sure," Hikari replied. "For now, we can't control the Yin Seal mark."
She was naturally talented and had already started forming the seal after practicing for only a short while.
"Then just cover it up when you go out for now. Once you can control it, you can hide it." Genya muttered quietly.
In his mind, he remembered Tsunade, whose Yin Seal mark was always visible, and Sakura Haruno, whose mark only appeared during battles. This suggested that the Yin Seal mark could likely be both visible and hidden depending on skill.
However, at their current level, neither of them could control it yet. It seemed they'd have to wait until they became more proficient.
"Genya-sama, this Creation Rebirth technique is way too difficult!"
Hayashi had given up on the Yin Seal for now and moved on to studying the next jutsu: Creation Rebirth. But this technique was even harder to master than the Yin Seal.
As for the Hundred Healings technique that followed, it had some similarities to the Eight Gates. Hayashi found it interesting, but since activating the Hundred Healings required a massive amount of chakra, he'd have to learn the Yin Seal first.
