Has a consensus been reached on Junko's backstory?
None has been reached yet, as far as I know.
I hear a lot of people saying Junko's son was one of the Suns Houyi shot down, but that doesn't sound right to me. Last I heard, Houyi was Junko's husband (and later Chang'e's), and the sun he shot down landed on Junko's child which also doesn't make complete sense.
Adding my 2p:
- I think Junko's story is based on the legendary account of Xuan Qi (Chun Hu) [see gilde's
post]. Evidence in favour:
- Xuan Qi had one child, a son whom Houyi killed, which fits perfectly compared to the notion of him being one of the nine suns shot down.
- Their names share the same characters. In fact, Chun Hu and Junko both mean "pure fox": "fox" for Junko's tails, and "pure" is self-explanatory.
(I admit that the evidence isn't much.)
- With the above said, I think Junko's story has nothing to do with the legend of Houyi shooting down the nine suns---this is where Hecatia comes in.
- Scrutinising their profiles, I'd say that Houyi is Chang'e's husband in Touhou lore.
Can someone please give me the real story (if we even know what it is)?
Houyi and Chang'e legends are messy, so ZUN had a number of different ways to go about it...
Nonetheless, another 2p: as to how Houyi fits with all three legends (i.e, sun-shooting, Xuan Qi, Chang'e with the immortality elixir), there is a variation (and there are a LOT) which allows one to account for all of them and (Reisen ending spoilers)
:
1. Houyi and Chang'e were banished from Heaven (Touhou's Moon) after the former shot down the nine suns.
2. He obtained the elixir, then Chang'e consumed it and floated away.
3. He became a tyrant following his separation from his wife, then presumably wronged Xuan Qi.
4. He was later killed and his spirit ascended to the Sun.
(Having typed all this out, methinks I need to revise my Chang'e-drank-Elixir-then-was-banished theory.)
Edit: Whoops, I've just realised that this doesn't address how Junko knows Chang'e is Houyi's spouse. In which case, swap (2) and (3).
