Kwang-Jo Han

Kwang-Jo Han, nicknamed Jo, is a Gemfighter. He is a member of an independent sect of Gemfighters, named Cassie’s Gang. His codename is Cepheus. His armor color is burgundy. His gemstone is titanite. His weapons are several kama, with burgundy handles to match his armor.

Appearance
Jo has a round face with soft features. He has thick, black hair, dark black eyes, and fair-to-peachy skin. He wears thick, black, square-frame glasses. He tends to stand out, being both on the tall side and the round side. When dressing casually, he prefers busy patterns and is fond of the color green.

Personality
Jo has a very self-important attitude. He can be clever, but gives himself way more credit that he deserves. He is also prone to celebrating victories too early, which leads to self-imposed ruin. Jo was diagnosed with an anxiety disorder, which manifests itself in him making many decisions and fallback plans to prevent his main plan from going awry. Most of the time, this method fails him due to shortsightedness.

History
Jo, like the other Gemfighters before being recruited, lived a relatively normal life. He had recently graduated high school and was packing for college. In order to recruit him into Cassie's Gang, The Goddess of the Dark decided to crush his prospective future. So, in order to manipulate him into joining, The Goddess of the Dark destroyed his future college and, as a result, destroyed his future. Jo, weighing his options, decided to join.

Shame Arc
Towards the end of the Shame Arc, Jo is seen on his knees, sobbing. He is just witnessing the news report of his dream college being destroyed by the Goddess of the Dark.

Cassie
Jo and Cassie are on speaking terms. He wouldn't consider her a friend outside of the given situation. Cassie doesn't much care for him either. They occasionally butt heads because of Cassie's harsh leadership clashing with Jo's visionary plan-making.

The Goddess of the Dark
Jo was forced into joining Cassie's Gang by the Goddess of the Dark. His relationship with her is not pleasant.

Morgan
Jo thinks of Morgan as a traitor for defecting to the Gemfighters team, and finds difficulty in forgiving him.
