Removing his Zanpak-tou from it's place on his hip and unsheathing the weapon--and thus awakening his shikai, the weapon's blade would become highly animated with seething arcs of electrical current that wrought electromagnetic presence about the area and the blade for the duration of it's release. The Blade was thus turned point down and forced into the ground, where then Aramand would sit indian style, both hands down at his knees while closing his eyes and in a concentrated manner, meditating even.
In truth, this was an practice often taken. A simple practice involving the training of his ability to sense, track, move and effect free flowing electrons in his vicinity however, it was a practice that would have the tendency to avoid attention. As with any time his Shikai is released the spiked Ion Activity and electromagnetic saturation of an area can often give rise to an area of effect that was expansive and large, daunting, as any storm would be.
So he'd have sat there, hands at his knee's, concentrating fully on the task at hand and creating wildly powerful and animated arcs of lightning that would not only move about his weapon but dance around his body as well, yet pale in comparison to the display before him as Ions were being collected and gathered to a single point, a marble sized sphere of ionic energy, now becoming a golf ball, then a tennis ball, and growing and growing. It was just a practice, and exercise done to pass time, but no less extra-ordinary to look at. HIs brows would furrow under the continued effort. His skin becoming slightly shiny under the strain of exercise and heat rising in the area around him.
His breathing was rhythmic, steady rises and falls in his chest that would for the most part go largely unnoticed unless someone was staring that hard to notice.
