Arthur is about to do some Godly shit right now. To me without Grace Shinra was never stronger than Arthur when hes at the height of his imagination, I think Arthur up there with Kuruno
@Fred23 the thing with arthur is that hes sorta like the hulk. the more hes immersed in his imagination of being King Arthur the stronger he gets, so theoretically he could just keep getting stronger and stronger as long as people keep fueling his delusion.
