Shukaku had been temporarily sealed.
The moment it was sealed, the remaining monsters flew into a frenzy and tried to come to its rescue. However, Kikyo wiped them out with several high-output Purification Arrows. The surviving monsters were frightened and had no choice but to retreat for the time being.
However, knowing the nature of monsters, Kikyo understood that they had not given up; they had merely withdrawn temporarily.
As long as Shukaku was not dead, the monsters would try every possible means to rescue their king.
Basically, the moment Kikyo and the ninjas withdrew, the monsters would come swarming back and try to break Shukaku's seal.
Thus, Kikyo had prepared another "safety lock."
Kikyo stepped forward and took out five arrows, handing them to the ninjas and instructing them to plant them at five locations around Shukaku. The positions had already been marked, and a spell caused the five spots where the arrows were to be placed to glow faintly.
Clearly, Kikyo intended to construct a barrier.
The barrier's purpose was to isolate Shukaku from outside interference, and given Kikyo's abilities, it was clearly intended to target those monsters.
Once the ninjas had planted the five arrows in their designated locations as Kikyo instructed, she immediately began constructing the barrier.
In an instant, as Kikyo formed hand seals and cast her spell, her sacred, pure white spiritual power surged forth, flowing from her feet into the earth before merging with the arrow in front of her.
When that arrow activated, its power spread outward in arcs, extending left and right toward the other two arrows before ultimately connecting with them.
Then, it extended again, eventually forming a circular ring of connections. The lines then all stretched inward and converged midway.
In the end, a massive pentagram magic circle appeared.
