Haruka Ouma is Shu's sister. She is the Senior Researcher of Sephirah Genomics, (which is apparently within the "GHQ") which was in charge of creating a cure for the Virus.


Haruka is a young beautiful woman with blue eyes and long straight black hair lengthing up to her back. She usually wore a magenta top and blue jeans with lab coat, but her attire varied.

Presently, she wears an office skirt with white shirt and lab coat in her official work. She later switches it with a tight blue suit. Her hair are now longer and fall to her shoulders. She is usually wearing a pair of red earrings along. At home, her attire consists of lavender coloured bra and panties. In an official party, she wore a wine red-violet coloured gown with matching earrings and her hair scrunched up in a bun.


She seems to have two sides of her personality, a serious side and a playful side. At work she is very professional, and usually stays at work for most of the week. At home she only wears her sleepwear, which includes her bra, her panties and a nightgown, even around company. She is willing to answer the door in her sleepwear, and is very playful with Shu. But she is very protective of Shu saying she must protect his future, even willing to have her arm get cut off in order to save him from the king's power. Despite pretty much abandoning Shu, she does love him dearly, and started crying when he regained his powers.


She is seen watching the bright light that shot up through the sky, which was a result of Shu's newly awakened power. However, it is not shown that she knew it was her son who caused that light. She is seen again in a meeting with some of the GHQ members as they talk about defective drug that was developed accidentally during the creation of the Apocalypse Virus vaccine.

She helps Shuichiro's plot to remove Shu's Power of Kings in order to make free him from the "fate of the king". She spoke to Segai Waltz about herself, describing to him that her motherly love was a harsh sort.

It was revealed in episode 19 that Shu and Mana are her stepchildren from their father and in episode 20 that Shuichiro Keido is her older brother.


  • Shu Ouma: Even though she doesn't see him much often, she loves him just as any mother would love her own child and is ready to do anything to keep him safe. She teases him by playfully threatening to come outside of her house in her underwear, to which Shu gets really panicked, as he couldn't see her in such an embarrassing state. It is, however, shown in episode 19 that Shu loves her the same and is thankful to her.
  • Mana Ouma: Haruka loved Mana just as much as she loved Shu before her death during Lost Christmas. Later on, when she discovers the truth of Mana, she stays neutral, and doesn't show any particular feelings towards it except her concerns of Shu's health and safety.
  • Kurosu Ouma: Haruka is shown to fall in love with Kurosu as she discovers more and more about him and explores his personality. She began to cook for him everyday, and blushed when she realized that Kurosu was thankful to her for taking his care. She is seen to be extremely grieved at his death.
  • Shuichiro Keido: She is shown to love her brother like anything and respect him from the bottom of her heart. However, when Shuichiro denies her relationship with Kurosu, she leaves him out of rage, and gradually her love decreases as she progresses her life with Shu. In the last episode, out of anger and rage for what Shuichiro did to her husband and her stepchildren (especially Mana), just because of jealousy that Kurosu had solved genomic theory and she had fallen in love with him, Keido commits suicide.


  • Tsugumi does not refer to Haruka as 'Mama Haruka' in the English dub.
