I love how Alto Yukimura's manga emphasizes how Challe and Anne despite being different species, having completely different life experiences, one being a young teenage girl and the other a 100 year old enslaved warrior fairy, feel the same solitude and are completely alone in the world, and have suffered great loss in their lives.
In vol one, we see Challe emphatizing with Anne and even rooting for her, he wanted her to win the medal because he knew that she would come apart if she didn't.
An overwhelming loneliness that permeated the body like an abyss. Challe was familiar with the feeling. He knew Anne probably expected it to vanish once she entered the Royal Candy Fair and became a Silver Sugar Master. Of course, if she failed to achieve the goal she’d set for herself, she might have a total breakdown. Challe figured it would probably be the latter. If those are the options, I hope she can do it.
I love how they understand this feelings in each other and are similar in this way despite their differences. I mean, Anne belongs to the human race who enslave and opresses fairies for their benefit, but she's just a lonely girl. Challe has been abused for decades, he's sick of humanity, and yet he understands her. They're kindred spirits in this way. What's most beautiful is that they become friends and aren't lonely anymore.
