to add on to what the person underneath (or above) said, the anime has the Orth segments happen with what should be happening in the Abyss. The day of Kiyui's birthday happens around the same time as the wait for Riko to recover. The manga instead cuts to Orth in order to talk about the Birthday curse, giving little indication to when this is happening in reation to Reg and Riko's journey (although I believe it is working the same way as the anime)
