MadWhite had always had his eyes on Ryuk.
From when the boy had first appeared in the Hierarchy test, he had been drawn to him, like a moth to a flame.
He had seen his abilities—ones which he felt wouldn't actually pale in comparison to any of the top ten family geniuses. One might see it as just Ryuk being just another genius, but MadWhite was no fool.
No human genius ever had any hopes of matching the geniuses from the top ten families, and he knew well that one such as Ryuk was incredibly rare.
And to top it all off, Ryuk was unknown.
The most talented human geniuses are very well known throughout the human world, and even the top ten families, but even with all his power, he had only managed to rank 205.
Ryuk was the special anomaly, and with nobody knowing him or him having much fame compared to the top ten family geniuses, he was the perfect hidden powerhouse to raise.
