From what I remember, they're both the all-powerful final big bads of two of Shonen Jump's most popular manga. Both lived thousands of years ago and were credited with being the originator of one of the series' most important concepts, with Kaguya being the first person with chakra, and Yhwach being the first Quincy. However, they ended up getting sealed away by one of the big goods of their respective series, though they would be restored to their full powers many years later by one of their henchmen. Also, they both absorbed incredibly powerful beings into themselves to gain even more power, the God Tree for Kaguya and the Soul King for Yhwach.
