Underwater.
Brian and Dean faced each other in their swim trunks, a hundred meters apart, utterly unaffected by the surrounding seawater.
Dean glanced at the Small Tachi in Brian's hand, clenched his fist in his right hand, and moved from stillness to a swift strike. In an instant, he threw a punch, stirring up a turbid explosion. The seawater shaped by the fist mark transformed into a white terrifying wave, charging towards Brian a hundred meters away.
The seawater surged oncoming.
Brian's eyes moved slightly.
Lines of force came into his view.
Following those lines,
he drew his sword abruptly and swung it down!
The sword turned water into blade.
The sword gang, formed from the waves, precisely struck where the surge was at its weakest, splitting the underwater wave with a weight of thousands of pounds into two, cleaving the terrifying force within it as well, utterly dissipating its destructive power.
"Eh~"
Dean didn't expect Brian's sword skill to be so fierce.
