Switching: Hatate to Chronoire Schwarz VI

[Ezrihel]

Oceanic Blades

At maximum, how many swords can she summon at once, and how many can she actively wield/launch at any one time? Does her concentration become increasingly strained as she summons more swords, active or not? Do the swords despawn on their own after a given amount of time/if they fall out of her range? How tiring is summoning these swords/keeping them summoned? Is it possible for the move to be interrupted by something (ex. an attack from an opponent)?

Also, first paragraph last sentence you have an extra "cutting" thrown in there, just thought I'd point that out :P
