Pauvina, now two years old, was far larger than Vandalieu when it came to body size. Not horizontally, but vertically.

Not only was she large, but she had high Attribute Values. Her abnormal Strength value in particular wasn’t something that an ordinary person could compete with. If someone were to have a serious arm wrestle with her, it was fairly likely that their bones would be broken or their hand would be crushed.
In regards to her strength, Vandalieu had sacrificed his own body to raise her, so it was apparent that she could do that without any problems.
