Mochizuki, Jirou

望月ジロー

An ancient blood vampire who allied with humans to combat the Kowloon children during the Kowloon Shock. Jirou was turned into a vampire in 19th-century London. He formerly served as a lieutenant in the Imperial Japanese Navy until he sustained severe injuries while protecting Alice in battle. In addition to being an Old Blood, he belongs to a unique lineage: the blood of the Sage. He wields a long katana with a silver blade. During the war, after defeating most of the Kowloon children, he earned the title of the Silver Blade. He is vulnerable to sunlight and water. He is depicted as being burned to the bone from remaining in the ocean for too long and emitting smoke under sunlight, despite carrying an umbrella. He has a younger brother, Kotarou, who is the only other vampire sharing his bloodline. He is regarded as the chosen Guardian.
