Cyborg Epsilon (サイボーグ･イプシロン) aka Shun Kazami （風見瞬); Shun meaning twinkle, or in a flash, and Kazami, meaning wind watcher.
The second newest member of the Custos. Was shown with a tragic past related to his younger sister before he became a cyborg. His real name is Shun Kazami (風見瞬). In the third part, he found out his sister and he are Larvaes. However, he accidently killed his sister due to lack of control over his powers. Since he was deeply traumatized of killing his sister, he ends up joining Custos after repressing his memories. His ability is to generate and manipulate fire at will. In part 4, he initiated Larvae Burst and gained full control over his powers and his body without the use of his power limiter. His powers also integrate with his cyborg enhancements and armor, making him stronger. He defected from Custos and joined the Attractors, even though most of them hate him. However, their view eventually changed after he saved Tei and Kiri. It was thought Shun also had feelings for Tei, but it was declined by Toshihiro Kawamoto and Makoto Watanabe during a Sokoani interview. Throughout Chapter 5-[[[The Eternity of Eternity|6]], he starts to develop a personality.
PersonalityEditOriginally, before he became a cyborg, Shun was a very kind and caring person, especially towards his younger sister, Lisa. During his time in Custos, he was just like any other cyborg; cold and near emotionless, carrying an intense hatred towards the attractors, calling them monsters. From chapter 4, he eventually starts to change his nature, and while in the process, it is possible that he became somewhat of a tsundere.
Finally, in chapters 5 and 6, although it is unclear, it can be said that Shun reforms a personality, being generally a pure-hearted, shy and sweet person like he used to be in the past, and on the other hand, being somewhat innocent, child like, and naive for his actual age. It is also very notable that Shun knows what is right and wrong, and will definitely try to avoid committing anything wrong. This personality is hinted at after his gentle smile shown in chapter 5.
Shun is 21 years old. He has a curly silver-blue hair with yellow-golden eyes. Shun's face is notably androgynous and considerably handsome; having a delicate face build and a somewhat feminine look. He is 181 cm tall, with blood type O, and weighing 70 kg.
Before he became a cyborg, Shun had purple-grey eyes, and a charcoal grey hair.
Basically, Shun has the ability to control and manipulate fire. After he went full power on chapter 5, he became able to incinerate or create large lasers with his powers.
