Idan, defending himself with his fiery wings, felt his defense getting weaker with each blow. And the number of tentacles was not decreasing, and if this continued, his defense would soon fall.
"If I'm constantly careful and hold back, I'll never be able to achieve more, — Idan thought, remembering the recent battle with outsiders.
In that battle, he could have won quickly if he had used his Spirit Form. He had a fire source given to him by his master, but fearing that it was his last trump card, Idan did not use it. Even when Erza appeared, he did not have the opportunity to experience this power in action.
"Let's do this," Idan said, and using his summoning ability, he brought Ned back. He then pulled out a sealed box and removed the seal from it.
After removing the seal, a huge amount of fiery energy burst out. Idan instinctively began to absorb it, not letting it go to waste. The absorption process was easy and smooth.
