brothers

This one is a crossover

You know how rin and yukio is the son of Satan the demon king

And meliodas is also so imagine if they met and their like brothers or some thing and meliodas knows but yuikio and rin doesn't

To change things up and not get it confused for a bit the demon king rules over two universe and he was actually planning to clash those two to make him rule and be strong cause in the other universe (sds) there aren't Exorcist so he'll have the upper hand

Meliodas is destined to be the demon king
Rin is the youngest and will also be the demon king on the other half  idk if you understand but yeah
