If you have no specific skill magatamas there's no another way to increase her skill level to max unless you have another Princess Tatsuha card or another deamon with the same skill to try for an increase in one level of the skill.

Like i said, it's not 100% so it's basically a risk and not worth if your deamon is a 4-5 star card. I rather train 2 of the same card. :/
