I see people really liked Ralsei's appearance here! This is how he'll appear in the Light World. Because his power is weaker here, they're unable to use their scarf for movement. Instead, he uses an umbrella (parasol?) for combat. He also uses it to block out the sun when outside.
There is a LOT that is WIP about this, but... Party Swap mechanic!!! You're able to swap between party members that fit into the same slot. It also works in battle, too! (video in reply)
