You are Kusajishi Riku, Captain of the Seireitei Court Guard's Ninth Division. The human world has been invaded by an unprecedented number of gillians, hollows powerful enough that anyone below a Lieutenant can't handle one alone. With you are several more Captains and Lieutenant-level fighters along with their manifested zanpakuto, but even these fighters have their limits. If the gillians keep pouring through the breach in reality that's brought them here, it would be enough to wear anyone down eventually.
“You're the menos expert in the Gotei 13,” Hitsugaya pants, having just tanked the blast of a cero. “I'm open to suggestions.”
“What else?” you reply , drawing your own swords. “We kill 'em until we run out.”
“I was expecting something more complicated.”
You shrug. “Sometimes the best plan is not to overthink it.”
That being said this does present a serious problem, one that you haven't had to cope with in a long time: exhaustion. You managed to partially recover from your accelerated Ura Hadō training with your zanpakuto, which brought you to the brink of death, but the fight with hollow-Muramasa and your first actual usage of the new spell you learned have undone some of that. You can't be sure how much more sustained effort you can put in before the last few days truly start to catch up with you.
It would be best to end this as quickly as possible, with as little effort on your part as you can get away with, but your companions have been fighting nonstop for just as long as you have. Yoruichi's still good to go, and the efficiency of Mirai's zanpakuto means she's probably spent the least energy getting to this point out of everyone present. But even Hitsugaya, Suì Fēng, and Rangiku are showing some sign of strain. Hitsugaya apparently still struggles to maintain his immature Bankai for this long, and Little Bee isn't really cut out for this sort of protracted battle in the first place.
