Axel von Ordelia's Links
He cares deeply for his little sister despite their parents' clear favoritism. Especially as the twins felt it was their responsibility to protect her while their parents fought.
Whenever his precious sister got hurt during the hard lessons she was forced to endure, he was close by ready to offer her emotional support. He couldn't do much in terms of logistics, but he could at least cook her favorite meal for her.
She would have likely given up many times if it weren't for Axel. Turning sharply from skating through life to suddenly trudging trough the trenches made every task seem impossible.
