If I knew the kanji, I would. But thanks for your constructive input.
yukio's kanji is 雪男 which literally translates into snow and man for the respective characters. I did some searching and it says it's a name for people born during December and lo and behold yukio and rin were born on 27th of dec.
Just found out the kanji for Rin’s name is the kanji for phosphorus...and phosphorus is Greek for lucifer. Not sure if there’s any additional meaning behind that, but I found it interesting. I wonder what Yukio’s kanji is.
