Chapter 286: Dancing in the Rain - The Fastest Hashira’s Bankai!!! (II)
How does one resonate the demon slayer marks with each other? Kai had asked Shinobu one evening.
The Insect Hashira had already chosen to impart Kai with all the secrets.
Even then, she had taken a deep breath before divulging the said information.
The appearance of Demon Slayer Marks opens the doors to two concepts, she had replied. Those two are — Transparent World and Selfless State.
Then she had imparted the knowledge about these concepts in detail to Kai.
According to Shinobu, the Transparent World was a special form of ocular extrasensory perception that altered demon slayers' visions, allowing them to perceive other living beings as if they were transparent.
The users could perceive the flow of blood, breathing, muscular contractions, and joint movements of the creature they were looking at.
It allowed one to see inside an enemy's body, letting them predict and evade their opponent's attacks and find openings for their own strikes. Not to mention, it also allowed one to perceive the surrounding world in slow-motion, thus skyrocketing their movement speed and reflexes.
The more the demon slayer marks, the better grasp over the Transparent World, Shinobu had added. When one truly attains mastery over the Transparent World, it causes the demon slayer marks to resonate with each other and hence allowing them to use Bankai.
On the other hand, the Selfless State is quite mysterious and demon slayer marks' presence doesn't mean one can attain mastery over it automatically.
Her explanation had cleared Kai's doubt but had also made him seriously contemplate a higher realm from his previous life.
