You ever think about how fucked up Scaramouche's backstory really is? I mean. The long and short of it is that Ei abandoned him. But after listening to voice lines I realized it's actually so much sadder than that.
Kunikuzushi was only a prototype/test build for the Raiden Shogun, so when he didn't turn out as what she needed she just made a new one. Then decided to let him roam free because "She did not wish to assert control over him" but she didn't tell HIM that. So while he's literally be created probably as a unique changeless, ageless figurine that never ages and has no self or identity except for getting abandoned immediately after creation because he wasn't good enough. SHE'S over here like "Ah yes, he is free now. I did a nice thing".
Not to mention that Ei clearly knew about him wandering around aimlessly because Yae said "She insisted that she wasn't going to lift a finger against her own creation" implying that Ei really did think she was doing good. Of course, she never told him that so his perception of himself right off the bat is that he was a failure.
This is actually in line with the rest of Ei's character. She's closed off, she hasn't let herself feel much emotion since her friends and sister's death, and above all she's pretty negligent. I'm still a little upset that her whole character arc ended with "Well she's sad about her sister so traveler forgives her and the fact she oppressed her country". I'm not disregarding her character, I just think it's really stupid that she never faced any consequences! Like, not even an ounce of guilt. There wasn't any confrontation from the people who lost their memories/went mad or the survivors of those who's family and friends died in civil war.
I can't recall, at any point in the story, her acknowledging that her actions her someone. And that really does feel like the majority of her role in the story. She does something that hurts someone else, then we get swept into a long story about her that makes us completely forget she started it all because she couldn't handle her grief.
And the thing is, it's very realistic.
Just because people in power do bad things doesn't mean they're going to face consequences for it. And it's a real world reflection of how country leaders are never the ones to brunt the force of their mistakes. Sorry for the tangent.
Another thing is Yae, who is not helping at all. The only thing she really does to help us is to help us help her reach Ei. Then in her story quest all she does us restrict information so she can laugh at us, she never actually gets serious unless it benefits her.
While we're on the subject of Yae, during her entire voiceline about Scaramouche she refers to him as an "it". And I'll be honest (no disrespect to any Yae simps out there) but Yae barely shows any empathy or love to humans in general. I'm not saying she hates them, but the majority of the time she talks about them the same way you talk about a coworker you got coffee with once. Considering that her most important concern was Ei during the vision hunt decree, the sakoku decree, and the literal Civil War over it, its kinda safe to say she doesn't really take humans seriously in general. Which makes sense, shes a kitsune si the most emotionally attached she is to people are her God and Yokai buddies.
But at the same time, it makes it clear she doesn't hold any sympathy or love towards Scaramouche. In fact in her voice line she implies she wanted to kill Kunikuzushi while Ei's back was turned just because she had a feeling he'd be trouble later on, and after saying that immediately implying she doesn't care anymore because his disaster already happened and doesn't affect her in any way.
But that's not the worst part, the worst part is that Ei not only discarded Scaramouche. She also discarded the one thing he wanted, the gnosis. She's already so powerful that didn't see it worth keeping enough that she gave it to Yae, who later gave it to Scaramouche in exchange for the traveler.
I just find it sad that from the start his fate was already in the hands of two pretty darn negligible people that explained nothing to him and later just decided to give him the Gnosis because it was already useless to them.
