... a sword

The place is a school for training of kendo... except that in the fight to be held here nobody would use a wood sword.
“Most of us live our lives without ever meeting you”, says a voice in the shadows; feminine yet hoarse, appropriate for a fighter. You cannot see the face, but you can tell (because of the small waist and the bulge in the chest) that it’s a woman. “That’s why many think the User does not exist.”
She comes into the lighted area. Asian traces, dark, long hair (hold probably by an elastic ring), medium sized breasts and a magnificent pair of legs.
“Nevertheless I have always knew better.” Her right leg advances, the movement revealing more of her thigh; the short robe she is using ends quite above her knees. One hand maintains a grip on the sheath while the other firmly grasps the hilt.
“What is your name, lady?” It is strange to talk to her as if she is real.
“Motoko Sutahara, holder of the key.”
What? Normally it was necessary to finish off lots of scumbags to fight the bosses. You have just started the game, and is already facing a gate keeper? Man, maybe this platform is really worth your credits. You draws your sword, but she strikes first. Her blade moves in an arc of ****, but you blocks it just in time. You try to unbalance the woman pushing her, but she immediately senses it, draws back, and attacks again.
Motoko’s movements are well beyond the possible for a real woman, but your own moves are also uncanny. The swords clash and you fight each other until you achieve a long cut in her robe. Due to her fast reaction a blow that should have slashed your adversary only ruined her cloth and scratched her skin.
