this'll be a bit uncharacteristically gushy, so listen closely.
i'm honestly not sure what i can say here what i haven't said a million times already. anyone who knows me personally knows how much i love sol and how much he means to me, yadda yadda. i'll do my best, though.
i've known about guilty gear since at least 2020 by virtue of proximity to friends who liked it, and even then i found myself a bit magnetized to sol, even if it was mainly because i thought he was hot. which hasn't changed over the years, i assure you.
on that note, i properly got into the series around august 2021, and in the months following i could rather definitively say sol was my favorite character out of the cast. the fact i did, bluntly, think he was hot did help with this, but i came to love him for much more than just that.
sol has a deep and inherent sadness to him, i think. he is a man who was changed irreversibly by the selfish actions of those around him, particularly those of one certain asuka r. kreutz, who sol put his full trust into as a friend. being deeply traumatized by these changes, he shields himself from the rest of the world with a bitter and uncaring demeanor. it's all a facade, of course: behind that shell, sol both hurts and loves deeply. his self-loathing is so deep that he couldn't recognize himself as human at all for over a hundred years, despite being loved by so many by the end of the series. all of this makes his arc of being able to reconnect with his own humanity and accept the love others have for him so deeply touching.
something about sol and his story simply spoke very deeply to me and continues to do so today. he is a deeply, perhaps even uniquely special character in my heart and i love him more than i could ever express in words alone.
