Mizu has seen and felt how Mirage Edge can be used. For much of it, she would not recommend being on the receiving end, a statement true about any decent sword. She takes those observations, including its use in hand and out, to inspect its form. The longer she has the sword, the more surprised Mizu is still to hold it. So she treats it seriously, a connection of form to function. It may be more enjoyable to wield the blade herself, at least through a series of exercises, but most people are protective of their swords, and Mizu has learned better than to need that. Besides, it's easier to see what decisions were made or how those decisions were manifested this close (this close while not being stabbed). It's never crossed her mind mid-combat to excuse herself with his sword for close inspection.

"Impossible," Mizu repeats, her eyes on the sword but nearly laughing. It hurts too much to laugh. "Arrogance like that will only set the foundation for my victory."

She looks up for a moment, a challenging gleam in her eye. "Some day you will exhaust the supply of surprises you have in store I have not seen yet. Each time you are forced to reveal one, you lose."

Sorry, humility is not among Mizu's skills.
