Regulus Decided Not to Be a Saint Anymore

Regulus: I'm going to Kariya's world to fight bugs. Is anyone going in a group? Black Cat: Big Thigh, please take me! I want to see my king! Mordred: Brother Lion, please take me! I want to see my father... Ugh! Watch Arthur and Lancelot fight! Saiki K: Brother Lion, can you come and help save the Earth first?
