The battle had just started but one of the Celestials was already out of commission! Kireina had dealt a great amount of damage on him and finished him off with her powerful Chaotic Spear, which had upgraded automatically into an SSS-Rank Weapon after she underwent multiple level-ups.
Her power was already admirable as a powerful summon, the first one that Gustav had summoned, and now, she had showcased her amazing power, which was enhanced even further as Gustav infused the power of the elemental spirit beasts into her aura!
"You bastard!!!"
The Celestial woman holding a bow unleashed her divine aura as she saw Kireina ruthlessly killing her ally, as she pointed her powerful bow towards her and fired a flashing divine arrow that crossed through the wind itself, reaching Kireina in an instant!
FLAAAAASH!
CLAASH!
