For "Uchigane" vs "Blue Tears", here's Riz and Gin (Excerpt from their duel in Vandam):
Spoiler for Excerpt:
An entire minute passed, and still no one moved. Gin's Tear had semiautomatic sniper rifle shouldered and scoped; Riz's Uchigane had her katana drawn and wings partially unfurled.
"W-What's going on?" Wondered one of the spectating students aloud.
"Simply put, they can't move," Karon answered somewhat absent-mindedly, as she watched the staring match play out.
"But they are still so far apart!" whispered another voice. "Uchigane needs to close the range, and Tears needs to shoot."
"Exactly that," Gou whispered, eyes moving for track the small adjustments each duelist was making. "Riz needs to close the distance, but her unit is a high-velocity system and will force her to commit to a certain direction. Oowashi Uchigane may be able to close the distance rapidly, but Gin is the best shot in our state. If Riz isn't careful, Gin can counter with several bullets at the right place."
"Then, shouldn't Tio-hime be at the advantage?"
"Not here. In this stance, Riz can parry Gin's shots easily, then go for a counterattack while Gin is reloading."
"...you make them sound super-human."
"Probably," Karon replied. "But they are ISpers, after all..."
"Everything will be settled with the first move."
Sorry, I draw heavy inspiration from Chinese martial arts movies when I do fights.
