From Johou Battle:

While she is Byakuren's most loyal disciple and right hand woman, Shou Toramaru is actually the current avatar of Bishamonten himself. Her devotion has proved invaluable to Byakuren and Bishamonten! Shou is honest and straightforward, and in public she presents herself with dignity and grace as fitting of her status but in private...

She can be a pretty heavy drinker, known to go on drunken rampages! She's also rather clumsy: She loses important items like#Bishamonten's Pagoda of Prosperity more than she's willing to admit.

She cares about her image, so let's keep all this a secret, okay?
