Yuzuriha Akiha couldn't believe her eyes for a moment, the little guy in front of her seemed to be younger than 15 years old, in fact, he looked more like 12 or 13 years old.
The most surprising thing in her eyes though was that she could easily feel that he was strong, there was inner energy inside his body, and it wasn't just a little sign of it.
The little kid in front of her clearly had surpassed the 3rd level of origin refining body, as he was still 12 to 13 years old.
Her shock became even bigger as she remembered his words though, as she clearly heard him say sister-in-law, despite her own age.
Her husband Takeshiba Tomiyasu didn't have a brother that was so young, so that left the only other option available, this kid was sent there by Eric.
She still was able to remember that when she had made a deal with Eric about the formulae that day, he had asked her body, her daughters, and a few others.
