While Shiro was undergoing Danzel's training on the basics of fighting against others, being through the ropes of necromancy and what dead mana is capable of in more detail.
Shiro was showing astonishing learning capabilities.
However, Danzel couldn't tell if Shiro was particularly talented in fighting or not, as he never really taught anyone else before her.
He was still surprised at how easy it was for Shiro to understand and implement new knowledge. By the fourth day, she managed to form a small amount of miasma around her hands without actually harming herself with decay.
Unlike dead mana, which miasma was extremely closely related to. It was extremely difficult for someone of the living to manifest.
Essentially the life force of the living together with their 'living' mana was tempering with the miasma.
