Sounds like a plan.
However, I'm afraid that the painting might contain some kind of garbage that will cause the character who destroyed it to suffer negative consequences. Of course, a plot is suggested here, where Guion sacrifices himself to save Beata, they cry for a long time and confess their love for each other, and then she grieves and embarks on a path of redemption, but I don't want to eliminate a champion.
And yes, I see Bibu and Bobu as two full-fledged champions, just for such cases, so that if something goes wrong with one champion, there is a backup.
