The Jubilee is a time of celebration for Catholics.

Traditionally, the Jubilee is held every 25 or 50 years and is a time to celebrate progress, free slaves (back when slaves were legal), forgive sins, etc etc.

In a great celebration, it makes sense to add a bit of pop culture flair. It’s also common to focus on children and youth outreach during the Jubilee and an anime character does a lot for that.
