Description
Prince Lumen is the twelve-year-old prince of Arachna and the leader of the Spider Riders. As the young ruler of the entire kingdom, he carries duties that include signing official documents, a task he finds far from enjoyable. Despite his age, he holds genuine authority over Arachna, and whenever issues involving the Invectids arise, he prefers to handle them through negotiation rather than force.

In personality, Lumen is bright, talkative, and fond of cute girls. He has a sensible head on his shoulders and often uses common sense when weighing the ideas and suggestions of Hunter Steele and the other Spider Riders. He is careful to think matters through, partly because he has no wish to hurt anyone. This cautious outlook shapes his style of rule, as he comes across as a somewhat lazy leader who would much rather talk out a conflict than fight, even against the Invectids. Some believe this reluctance to do battle stems from the extraordinary power of his spider, Ebony, whose full strength he may be afraid to unleash. He only fights when it is truly necessary.

His bond with Ebony is one of his defining traits. Ebony is just as chatty as her master and constantly offers Lumen advice on ruling Arachna, refining his battle technique, and even dating. Their relationship is that of a close, talkative partnership, with Ebony acting as both his mount and his counselor. In combat, Lumen wields a sword, sometimes described as a chain sword, and relies on Ebony, who is noted as an exceptionally powerful spider even though Lumen holds her back from fighting at full capacity.

His romantic side comes to the forefront in the episode centered on his love life. When the Invectid warrior Beerain disguises herself as his childhood friend, Lumen eventually discovers the truth but still willingly gives her the Oracle Key. After Beerain is blown away and his real childhood friend arrives, Lumen keeps searching for Beerain and calls her his true love. This shows that beneath his easygoing and diplomatic exterior, he is sincere, trusting, and deeply affected by matters of the heart.

Overall, Lumen is a careful, peace-loving, and warm-hearted prince whose leadership is defined more by reason, conversation, and loyalty than by aggression. His development over the story highlights his growth from a passive and somewhat lazy ruler into someone willing to make personal sacrifices for those he cares about, while his abilities as a sword fighter and rider are complemented by the wisdom and counsel of his spider partner.
