I meant "an alphabet which does not has a meaning", such as a and b. But looking at your conversion to single letters, it seems to sufficiently help people to understand. I just could not imagine that single letters such as I, X, and V, can work as shorthands in that way. They look good.

緋 is kind of red, and is a portion of the name of her skill. It pronounces in the same way as 非, and her skills includes both strings 非想 and 緋想. Since 緋 has a "richer" shape than 非, 緋想 looks greater than 非想 for us.

幻 means "illusion" or "looks as if it existed", and 妄 means "imaginary" or "existing only in minds". 夢 means "dream", and also means "non-existing" or "was believed to exist but the possibility has vanished".

亜 means "quasi-", "semi-", or "near", but is frequently used to express sience (fictional) stuffs. For example, 亜 space means something like a unreal place, 亜 light speed means a high-speed approximated to light speed, which apears when we talk rockets or quantums. I used it to express Phi_1(0) (the least omega fixed point) because it frequently plays a role as a collapse of the weakly inaccessible cardinal. (Namely, it is a "nearly inaccessible").
