First, I'd like to know if Nero generally starts with Yamato, or only does so some of the time.
Second, I'll bring some information from the previous thread.
She generally fights by casting magic from a distance and, while she may not take things too seriously, in a fight to the death she will fight to the best of her ability, she isn't a close range fighter so moving away or casting a spell right away is fairly likely. She isn't likely to go melee range and if she is forced into it will likely back away or cast a spell that holds Nero still. She uses her summons quite a bit, guardians can be used as melee weapons if neccesary, but also as projectiles that cause explosions and a means of flight. Normin just drop on the enemy en masse and cause numerous explosions. Practically all of her spells are AoE. If Nero gets into melee range, it would be in character for her to cast a gravity spell to hold him in place while she gains distance. As mentioned below, her spells have statistics amping/reducing properties on nearly all of them, so Nero will be getting weaker as the fight goes on as she only grows stronger.
Some relevant abilities:
Gravity Manipulation: It's the type that holds you opponent in place while you're free to do things, she can set traps that do this too, with Gravity Mine.
Life Manipulation: A property of many artes in general, she gets healed while fighting
Summoning: She can summon the spirits of 49 normin (A type of malak, comparable to her) and rain them down on the opponent, she can also summon Guardians, a type of paper creature that she can also fly around on like a hoverboard, they can also change sizes
Stat Amping/Reduction: It's at least 50%, I believe it can go up further, it's a property of most of her attacks, it works on enemies when hit and on herself when she casts, she can slow down the opponent fairly significantly (About 4x)
Poison Manip: It's there I guess, a property of some artes, it damages over time.
