Inside the Mask Storage Hall, Tanuki Treasure had just strapped all nine masks onto its back and seemed fully recovered.
As Akaseki waited for Ranwu to bring food, something occurred to him, and he sat back down.
"Checkup!" While immersed in The One Who Died Is Your Mom, Akaseki had felt a faint change in his chakra.
Sure enough...
Leaving aside swift flame, scorching heat, incineration, and overspread burning—the familiar four corresponding to joy, anger, sorrow, and happiness—one of the two entries that had always shown as "unknown" under his Fire Style chakra had now revealed itself: burst flame (1.09%).
With a slight application of his Fire Style chakra, Akaseki understood that the transformation represented by "burst flame" leaned toward explosions and impact. It could give Fire Release Ninjutsu more force on impact, and with sufficient mastery, he could learn those advanced Fire Release Ninjutsu that focused on explosions.
As for where "burst flame" came from...
This must be "urgency," right? Akaseki reflected.
Such sudden progress had to have a cause. Considering the plot of the short drama he had just watched, the most likely explanation was... urgency.
Joy, anger, sorrow, happiness... urgency. There was still one more to explore!
Another thing that concerned Akaseki was "scorching heat" and "incineration," the two corresponding to anger and sorrow. One had come from genuine emotions, while the other had come from being swept along during immersion. Both had progressed extremely quickly, racing far ahead of the rest, but that brought a problem...
Whether it was because they were too far ahead or because the difficulty had sharply increased after passing 10%, both were now hovering around 12%, barely moving at all!
*Perhaps next time I should try using anger and sorrow to guide the Sharingan into stimulating Lightning Style or Earth Style
