A Calculated Surprise
Just as Rebecca's dark and icy attack hurtled towards the Thundering Reaper, the air around Anna vibrated with a palpable tension as a guttural cry escaped from her throat,
"Yaarrgh!"
*KRAAAKKKSH!*
Suddenly, a dark yellow burst of explosive lightning erupted from Anna's being in every direction.
The sheer force of the explosion sent shockwaves ripping through the landscape, hurling Grace, Rebecca, Emiko, and Yui backward until they crashed to the ground with tremendous force.
Grace and Rebecca, being closest to the Thundering Reaper, bore the brunt of the lightning blast.
They coughed up blood, their bodies splayed out on the rough terrain, too injured to move. Emiko and Yui, although they had been standing farther away, were also severely injured.
Their power levels of low-level A Rankers and correspondingly weaker defensive powers left them particularly vulnerable to the peak Soul Devourer's explosive attack.
