Bonten is one of the two guardian deities responsible for protecting the Buddhas. He is a meticulous, rational man who faithfully supports Lord Shaka Nyorai.
His orderly thinking aids his allies, but can also trip him up at times.
He prioritizes Lord Shaka Nyorai's orders above all, even throwing himself into trouble to execute them.
