After that, Rahu repeatedly tested Ketu's powers. And he was astonished, although they still weren't on his level.
Ketu was in a league of his own, aside from the prime Yveline. It was safe to say that he was the strongest.
Not just that, in a mere few days, his intelligence also rapidly increased, making him suddenly aware and conscious of his existence and his master.
Aside from the core powers of his physique, such as the Dimensional Devour…Ketu could use the dimensional energy to the fullest. The death energy, even more like Rahu, had become the perfect undead. Aka, he couldn't be killed.
Ketu didn't have a soul to be truly dead; his body itself was his soul. And the soul his body.
Now, the question of his race arises. What was he exactly…was he an Undead or a Dimensional entity?
The answer to this question is…both. Yes, one of a kind. Now this raises another question…what was Rahu? Was he a perfect undead like Ketu?
