"Demon Spell: Burning Abode!"
Altashia's flames that had spread all over the battlefield due to her flying slashes started converging in the airspace of the battle ring. They quickly closed in on Eren as he was getting closer to Altashia.
Altashia had dispersed her black wings because she couldn't have maintained them for a long time anyway. The second reason was that she wanted to cast this spell.
She wanted to create a space between him and the approaching Eren while he came close to the ground. This was so that she could control her stray flames in the vicinity. Her Demon spell was fueled by the existence of her stray flames in the vicinity after all.
The flames changed their shade to a golden hue as they converged around the falling Eren. Their temperature also seemed to have shot up due to the demon spell's amplifying effects.
