Pacific Ocean, northwest.
Beneath the sea east of Honshu Island lay a trench 890 kilometers long and 100 kilometers wide, with an average depth exceeding 6,000 meters. Its deepest point was southeast of the Izu Islands, reaching a depth of 10,374 meters.
It was one of the deepest trenches in the world, connected southward to the Ryukyu Trench and the Mariana Trench, the deepest known place on Earth.
The deepest section of this trench, east of Kashima-nada on Honshu Island, exceeded 8,000 meters, reaching a full 8,412 meters.
Above this trench, over the churning sea, a figure silently stepped out of a semicircular Gate of Darkness. He walked through the air as if treading on solid ground and arrived above the ocean.
"Is this the place?"
Looking down at the turbulent ocean below, Riezel sighed inwardly.
"I never thought Kengso would place the Prison Realm sealing Gojo Satoru inside this trench and throw it onto the seafloor more than 8,000 meters down."
"Just how wary is that Kengso of Gojo?"
Thinking of that, Riezel actually felt somewhat fortunate that the one who had been sealed was Gojo Satoru rather than himself.
Though both of them had been feared and targeted, Riezel was undoubtedly far luckier than Gojo Satoru. He had merely been excluded from the Culling Game rather than sealed away.
If he had been the one sealed, perhaps he would now have been sunk into a trench over 8,000 meters deep as well.
"Of course, it would be impossible to seal me in the first place."
With the Development Ability Unrestricted, Riezel could not be restrained or sealed.
Kengso was lucky not to have chosen him as the target of the sealing.
Boom!
Riezel suddenly shot straight into the sea like a torpedo, plunging toward the seabed at astonishing
