In stark contrast to previous entrant Rosalie, we have the same type of character with better execution.

Amelia is the justice loving princess of Saillune, raised by her father who instilled in her the righteous path of justice.
What that means in laymans terms is that the King and by extension Amelia, are the main defence for their kingdom.
While Rosalie's troops come down with a bad case of death, Amelia actively makes sure that all her troops survive any ordeal that comes their way even if it's sometimes from her own ally Lina Inverse herself.
Having returned to playing Dynasty Warriors recently where these fancy buzz words are thrown around all the time, it's refreshing to find a character who can live up to their boasting for once, even if you do get sick of it by the end of her debut episode.
