any headcanons for first? angsty or not?
I don't know if it counts as headcanon, but I'll take advantage of your question to yap about my ideas of Wars and First being a close duo like Rulie and Leg (Bc I'm really excited about the idea but I haven't had a chance to draw anything and I'm about to explode).
To begin with, I know that the idea of Wars and First not getting along is tempting (I was almost tempted by that thought too), but we've already seen that dynamic with other characters, mainly with Legend. And, although I really enjoy those kinds of rivalry dynamics, I think the captain deserves to have an equal with whom he can be silly and do silly things.
He has a brotherly bond with Wind, but the age difference makes him act more like a concerned older brother. Twilight and Sky are also there, but Twilight is closer to Times, and Sky fits in with the whole group. To the rest of the Chain, he continues to strive to present himself as the responsible one.
Now, First seems to be a fairly relaxed and focused character. I get the impression that he would really enjoy listening to Wars' topics of conversation, and his presence could help him calm down and slow things down when necessary (As if they were about to do something stupid, Wars hesitates but sees this super cool and calm guy and says, "Screw it, I'll do it" and they unleash their chaotic nature). He also looks like he's been through a lot of shit in his life, so he won't be far behind when it comes to getting serious.
In short, he seems like the kind of person who can keep up with him and at the same time help him stay grounded when he needs it, like Rulie and Leg but more reserved in their camaraderie.
Then you'd see them on one side of the camp, telling stories and anecdotes, practicing sword techniques, or plotting to convince Wild to prepare a certain dish for dinner. Wars would undoubtedly use First's cool attitude to dissuade the others if necessary.
Furthermore, if there is any kind of rivalry, it would be healthy competition.
And when their journey is over, they will exchange their cloaks.
(I know this is a lot of speculation, and my perception of the Chain is more focused on the fandom's characterization, so I'm just rambling. But I genuinely think they'd make a great duo. Wars deserves a brother of his own to tease and be teased).
