I've done quite a few rp's with first person, and so long as the character was indicated, it never became a big deal, so its not a primary concern of mine unless people feel overwhelmingly discomforted by it.

Ok, now this is where it may get complicated. The host twin can, as you mentioned, only recognize the placement of the soul twin depending on the relationship between the two. The soul twin, while intangible, has its own eye and sensory information, meaning at any given time, a host twin can [i]feel[/i] or [i]see[/i] with something of inner eye where the soul twin is located, but not see the soul twin within their physical reality. This changes as the bond increases between the two, where it becomes possible for the host twin to discern the soul twin as a glowing orb of some color in their vision, but something that remains unseen to all others except other host twins.

I should also mention that the relationship with the soul twin affects the host twin's perception of spirits; that it to say, a host twin with a poor soul twin relationship will sense spirits, but their eyes will not make out bodily creatures. However, a host twin with a good relationship will make out discernible creatures, which may appear somewhat transparent and blur and in and out of reality. A host twin with a powerful relationship will be able to see other spirits quite clearly to the point where they may look extremely solid.
