Kanon Ozu (小津歌音, Ozu Kanon) is the twin sibling of Shion Ozu and the eldest of the Ozu sisters. She is a third-year student, and a member of the Coppelion Clean-up Crew, alongside her sister and Haruto Kurosawa.Kanon is a slim teenage girl, with blonde hair and amber eyes. She wears a white blouse, a blue ribbon bow tie, and a orange cardigan. She also wears a blue skirt with brown high heel boots. During the winter, she would wear a brown coat, dark red mittens, and a red plaid scarf.Kanon's personality is a bit of a paradox, really. She harbors a well-polished dislike of humanity that teeters on the brink of mistrust. Whilst the more subdued, of the two Ozu sisters, below that seemingly calm facade lies a psychotic young woman, prone to fits of insane laughter that once provoked, possesses little regard for human life, often displaying a wicked, vile grin - something that's shared between her and her sibling. She has little time for failure - should she not complete a task, she becomes akin to a wolf and it's prey, hunting down her target without relent until the deed is done. But alas, Kanon isn't completely 'broken', so to speak. Despite her actions, she genuinely cares for her twin sister, Shion, and will destroy anyone who would try to harm her in any way. This mainly stems from the horrific experiments carried out on her sister whilst at the academy. It is that perception of how heartless humans are that fuels the good majority of Kanon's hatred and cold persona. Her hatred from humanity has quelled in recent times though - of course, she still despises them for their shortcomings; though on rare occasions, she displays a touch of mercy towards them, however subtle it may be. Her respect for following JGSDF orders is simply non-existent, which results in her carrying out a mission her own way - most often rather violently, unless the likes of Ibara Naruse are there to coax her first - even then, the violent approach often prevails. It should go without saying that Kanon has a great fear of water, given her electrical powers. If a body of liquid is nearby, she can often become virtually paralyzed on the spot - not willing to risk the chance of harming herself. Arguably, one of her other greatest weaknesses is her fear of death. While she possesses no qualms about ending a human life herself, Kanon lives in a state of constant fear of dying. Coppelion do not age like normal humans - sure, while they are undeniably hard to kill, their natural death can happen at any given time: being completely spontaneous. As such, she harbors a grudge against humans that borders envy for their mortality. Aside from this, Kanon is highly intelligent, despite having not paid any attention in the slightest to her classes whilst training. Her main areas of interest include Nuclear Reactions, computer technology and just about anything science-related. Naturally, she is quite headstrong and stubborn - which often leads to a clash of opinion with others, most notably Naruse.
