synopsis only talks about Elijah and his brother, but is tagged as female mc. mistagged or just usual mtl pronoun confusion?
Had to go look at the original DLsite Japanese description to actually get an idea of the game
Seems like Female Protag is correct, since the MC seems to be Eriya エリヤ, the girl in the CGs. (Not Elijah imo, while it is the correect katakana for the biblical name, contextually I think it's pretty obvious it's meant to be read phonetically as is, since it's closer to a girl's name. Unless the author did a weird and gave a guy's name to a girl...)
The original synopsis says ”エリヤは兄のセイン” which afaik reads as "Eriya, with her brother Sein" which the MTL gabungled into "Elijah and his brother Thane", as the most likely result since it can't into japanese context cues, with both names of dudes which caused this confusion in the first place
So going by that, I think it's safe to assume it's mostly from Eriya's POV so the tag
female protag would be correct.
I haven't played it yet though so do correct me if it isn't majority female protag POV in which case the tag would indeed be wrong.
