Identifying the secondary characters in the first image is too easy, the girl's name is Vegas and the boy's name is Altair. Even without reading the prologue or any of the characters routes, it' seamy to tell who's who!
I mean Vega
Yeah, but only if you know about the Japanese Star festival and it's story. I only know it because there was the Stargazing Event in the Gree version of BMP and there they told the whole Star Crossed Love Story...
"there are other gods you haven't met yet..." Omg, are we gonna see MORE gods being added ? Maybe in a second season ? Oh wow, so much possibility ! xD
Yeah, there are a lot of other Gods actually, but I guess the Main Characters are the 12 zodiac Gods. I made a "other Characters" Page where I added the other Gods too, if you want to take a look ;) -> http://otomeotakugirl.blogspot.com/2015/02/star-crossed-myth-other-characters.htmlI think they will be added later, maybe like you said in Season 2.
