Thunder Striking in Blue Sky was an extremely powerful lightning elemental move. But instead of this being a lightning elemental technique, it was actually a sword technique that was using the lightning element. The power of this move was insane but after using it Tomoe would be out of her MP so she will not be even able to move her body properly after executing this move.
The lightning that covered the whole field did not last for too long and soon everyone was able to see the arena again. In the middle of the two of the combatants were standing in the after attack posture. It looked like when Katerina felt that Tomoe was about to unleash her strongest move, instead of defending against the attack or dodging it, she did what she was best at and attacked her back with her own strongest move.
