That's right.
The tiny soul that appeared in Imu's palm
belonged to Zenon Zogratis from the Black Clover World!
A devil host of the Spade Kingdom, one of the "Dark Triad."
He possessed innate Bone Magic, as well as the Spatial Magic bestowed upon him by Beelzebub.
Because Beelzebub had unexpectedly died at Imu's hands,
he had been unable to raise his "devil power" to one hundred percent during his battle with Yuno, one of the "two protagonists."
In the end, he died beneath Yuno's "Sanctuary Magic: Spirit of Zephyr" sword.
And because Zenon had signed a devil contract with Beelzebub,
after his death, his soul had automatically come to Beelzebub's "hand" under the effects of the contract.
Unfortunately, Beelzebub had only a "heart" left. Zenon's soul had thus fled into the heart, and his consciousness had fallen dormant.
Now that the heart had been absorbed by Imu,
ownership of Zenon had transferred into his hands as well.
What a winding journey that had been.
As for what use Zenon's soul had?
Well, it was certainly useful, but Imu simply put it away.
He had no time to study such matters right now.
The effects of his second awakening and the changes to the Star Map were what mattered most!
So Imu merely greeted Stussy,
telling her to stay here with Teresa and relax for a few days.
Then he directly opened a Small Star Gate and returned to Mary Geoise on Sea Star.
Once again, after so long, he sat upon the true Empty Throne.
He did not summon the Five Elders.
But he could sense Karna, in spirit form, and the invisible Falcon Dragon silently guarding the left and right ends of the second-tier platform.
Imu was very satisfied with this.
That was what the Shichibukai were supposed
