It's kind of funny how literal some of the demons names are. Byakkomaru literally means white tiger, Raimeiki literally means thunder demon, and Kiseki-o literally means "King of the Demon Box." But this also brings up other questions, like why their names before they were vampires are what they are. Apparently, people name their children Raimei and Kiseki, but Byakko is technically a surname and if you are familiar with some East Asian mythology you've probably heard of the White Tiger of the West, or Byakko, in Japanese.
Out of all the demons, Byakkomaru is the most loyal to his name, manifesting as white tigers and even wearing a tiger cloak in his more humanoid form. This kind of makes me wonder if he (and Raimeiki, Kiseki-o, and Gekkouin) was something else before he was a demon/vampire.
When ancient Yuu, Ashera, Krul, and Noya go to see winged Mika way back when, Noya mentions something about how Mika is what all of them were supposed to be. In other words, perfect Michaelas, whatever that means. Michaela, or Mikaela, means "who resembles/is like God." The Michaela in Ancient Greece is said to be Sika Madu's son, but for whatever reason, he attempts to make others, and there are characters who have the "Michaela trait" (Mika, Crowley, and Ferid). Krul, Ashera, and Noya are known to be human before they become vampires, but what about the others? Demons don't have to be vampires before they turned, though those who aren't are all human, rather than something else.
Sika Madu is someone who I'm not entirely sure of being a vampire before becoming a demon, at least not completely. He's able to manifest wings, for example, which are very seraph-like in appearance and he's also the first vampire, and how he came to be so when all vampires apparently have to be turned by others is unknown.
There must have been something special about those Shikama Doji had chosen, especially considering how he didn't choose Krul and Ky Luc, who are also both third progenitors, or even Rigr and Urd, who were/are second progenitors and technically would have more powerful than the thirds. Actually, I'm curious. All the sixth progenitors and above were sired by Sika Madu, but for what reason do they have more/less capabilities? Is the amount of power they gain random, or is the sire able to choose the amount of power bestowed upon them?
But I digress. No one would name their child "Byakko," so I'm wondering if this hints at some sort of different pre-demon existence. It's also possible that this could just be a chosen name or a nickname and I'm looking into it too much.
