Idan, having attacked Erza with spears of light, realized that his attacks were not strong enough to destroy a being like Erza.
Due to the unusual situation where the suppression of the world was weakened, Erza's rank was not suppressed to the fullest extent. Idan was aware that his and Arabel's attacks, even though they were Platinum-ranked, could not instantly destroy a real Diamond-ranked being.
Idan found out that with each increase in rank, the difference between the ranks becomes more noticeable.
If earlier, being of the silver rank, they could easily defeat creatures of the Golden rank, now, having reached the Platinum rank, Idan was not sure that he could also easily cope with beings of the Diamond rank.
As he was about to attack, Idan, while in the sky, suddenly noticed a bright flash of light that rushed towards Arabel, who was standing on the ground.
"Belle!", — Idan shouted, trying to warn Arabel.
