Let The System Talk

Kafan, Luan, and Sister Orb looked at them. Every time Rean and Roan started to exchange elements, their hair would change into a mix of Black and White Colors. Those moments were when you could truly tell they were twins since even their hair colors became the same, not only their bodies and faces. Right now, their merged form is exactly the same as when they were exchanging elements. This Rean...Roan...Reoan...Roean... or whatever had that mixed hair color. The only difference was that their merged form was slightly taller than when they were separated.
