His sword detects any evil aura and sure enough whenever Kuroboshi is around his sword detects it. He proclaims himself Kiyo039s bodyguard when he learns that Kuroboshi is a vampire. He fights Kuroboshi during the Romeo and Juliet play and he still claims his position as bodyguard because he claims that Kuroboshi is weak.
