Manga Deviation Ep 5 (Arthur)

In the anime Obi ordered Arthur to be an escort to Vulcan's team while in the manga Obi didn't order Arthur to escort Vulcan's team because he assumed that they were the first to arrive in Amaterasu. This creates a major deviation for the upcoming episodes since Arthur's long rematch with Dragon started after Charon was shot.

P.S. Arthur is conserving his energy for when Dragon arrives thus his non participation on the defensive fight.
