Hmm 🤔 Well, even though human can freely pass through the gate and god's envoy were also sent to the underworld several times, I guess they couldn't go too deep into devil's territory. At most, they can only acquire a surface level of intelligence about the devils' force and that where SYX's mission this time was very important. So, that mean, she can only returned to Radiant Continent when she fully unlocked her devil seal (and use her human form to pass the gate) or when the seal on the gate was collapsed.
