Is this a checkmate?

Quite a massive amount of mana was gathering on the sword, turning them into magical energies.

He had no idea what she was doing, but he couldn't just wait for her to complete what she was planning. He summoned a chakram on his palm, then fired it to Josie Finn. The chakram traverses the space between them in a split second.

But he gawked at the result; that chakram had disappeared like smoke upon reaching her vicinity.

Yman couldn't hide his surprise. 'That fearsome chakram disappeared just like that?' It was truly unbelievable.

"Quite troublesome," he mumbled while squinting his eyes. He sent another chakram, but the result was still the same as the other one. "As expected, those energies are too much for my chakrams," he frowned and exercised his fingers which turned stiff.

He couldn't risk charging in without knowing what she was planning. He had a suspicion that she was planning a super-powerful offensive strike.
