Puppet Butler

Puppet Butler is the fifth mysterious dark butler who bribes Kirika Kuzuha with sweets to let him attack Hayate. He wears a mask, top hat, and a black cloak. He looks like Kimihiro Watanuki from xxxHolic and has hypnotism powers as well as a personality resembling that of Lelouch Lamperouge from Code Geass. With it, he (loosely) controls Nagi to bring Hayate to him. (Source: Wikipedia)
