your hc on the tiaras being the eyes of serenity makes me wonder if you have any hc about the planetary symbols on the foreheads aside from it being the natural state

Mmh, let’s see. Not particularly I guess, if anything I think I’d take away stuff from canon.

Like in canon is implied that the symbol appears when a senshi “needs help” or “is willing to help”, I don’t have that, cause that would imply the symbols inherently being tied to the team rather than to the individual, or it could mean that the senshis are inherently born to be tied in a connection where they would need this type of almost instinctual communication engrained into their being in the first place.

The ladder isn’t an inherently bad idea and I think you could go very interesting places with it, but I just haven’t gotten that far.

That really cuts to the question of: what is a senshi? Why do they exit and what is their purpose? And I know we have an answer in canon, but I don’t particularly love it, so I’m reworking the whole structure from the ground up.

In the general sense though, the symbols just stand as a way of identifying if one is a senshi or not. A weird analogy I have for it is like the red markings on a black widow, tho in the senshis’ case it doesn’t necessarily mean they’re a threat and the symbols is a warning. The symbol just is, as far as we know, and it’s prob not as easy to understand as the red markings on a spider.
