 The story in the OVA differs slightly from the manga plot.A pyramid appears in London which causes Inaho's heirloom earring to glow, she emotionally blackmails Mosquiton into helping her get to London from Shanghai despite his cautioning about the dangers and that immortality is not what she thinks it is like.Meanwhile, in London, Count St Germaine influences the army to investigate the pyramid regardless of the cost in man power to the pyramids defenses (traps and animated mummies).
