This was the first time Rea unleashed this power on the battlefield. Theo once showed her that she could actually merge her embodiment, creating a new form of embodiment.
And she had been working on it the whole time. This was the answer that could allow her to reach her father's level despite being less talented.
However, it was still too early for her. Every time she used it, her Magic Power would be drained and her condition would deteriorate quickly.
This looked like when Theo first had his Alter Ego.
'I have been training this ability the whole time. To combine two embodiments at once is to merge the existing temperament and power. They are different, so the two embodiments will clash in my body.
'I've been using my energy and Magic Power to suppress them, but I don't think I will be able to use them for too long.
