Kiryuo Hikifune's inspiration to merge the "Temporary Soul" into herself had come from Soul Reapers and Zanpakuto.
Being unable to use Bankai inevitably meant a reduction in the captains' strength.
A tenfold increase in spiritual pressure and a fivefold increase might seem to differ by only twice as much, but the actual strength they could exert was far beyond anything that could be measured by a mere factor of two.
