Guy Crimson

Guy Crimson (ギィ・クリムゾン), also known as Rouge (原初の赤) is known as the first of the Primordials and the first seat of the Octagram. He resides in the Ice Continent.

Appearance
Guy is portrayed as handsome man with blood red eyes as "stars of gold and silver dancing in them". His wavy, burning hair is a deep shade of rouge. He's about as tall as Leon and his beauty is prideful and distant. He looks like someone born to lead and conquer. He has his clothes draped over himself, revealing a lot of skin.

Personality
He is typically characterized as prideful and relaxed. He doesn't usually pay much attention to others, but if someone catches his interest, he will attempt to get closer to them. He displays a forward approach in his relationships, often making suggestive and openly sexual advances towards Leon Cromwell while in his male form, despite Leon's clear preference for women. In response to Leon's rejection, Guy repeatedly offers to transform into a woman, only to be turned down.

However, Guy can also exhibit a caring side towards individuals he recognizes and acknowledges. For example, he continues to engage with Rudra in order to prevent his friend from falling apart emotionally, and he even threatens to become Leon's enemy if Leon harms Ramiris. Additionally, Guy demonstrates a level of respect for those who show no fear towards him, becoming more casual in their interactions. He takes his role as a mediator seriously, and he displays noticeable anger when Rimuru disrupts the balance of power that Guy had maintained for thousands of years. Guy is particularly interested in strong individuals, especially those who possess Ultimate Skills.

Background
Guy was born during the dawn of time, before the creation of heaven and earth. He was one of the demonic counterparts to the Seven Angels of Origin, having split from the Great Holy Spirit of Darkness. As the first among them to be born, he ruled the Daemon Realm as its king and commanded the daemons at will. From his perspective, even the other primordials were mere dependents. However, when Bleu and Vert challenged him in a bid for supremacy, he easily defeated them but discovered that the primordials were immortal. No matter how crushed they were, they would resurrect under the victor's command. This realization led to a stalemate among the remaining four primordials.

Among the daemons, the Black Primordial Noir persistently troubled Guy. They fought for supremacy, resulting in a draw. Recognizing Noir's strength, Guy acknowledged him as a rival.

With the passage of time, Guy was summoned to the Central World by High Human Emperor Jahil of the Super-Magic Empire. He was summoned as an Arch Daemon and tasked with destroying an enemy nation. Using a million corpses, Guy successfully incarnated and ascended to the rank of True Demon Lord, acquiring the souls of numerous people. In addition to destroying the enemy nation, he summoned Primordial Vert and Blue, ordering them to slaughter Jahil and all the residents of the Super-Magic Empire while avoiding mass destruction magic to prolong their suffering.

As Guy crushed his enemies, he relished in their doomed pleas and found it to be a pleasant sound. He named himself Guy, realizing his awakened state was needless since he already considered himself the strongest. He named his companions Misery and Rain, reflecting the misery of mankind and the blood that fell wherever he went.

Guy and his maids traveled from place to place, enjoying the world. Eventually, he encountered Veldanava and challenged him to a fight but was easily defeated. Instead of becoming Veldanava's servant, he was given the role of Mediator. It was at this moment that Guy's heart materialized, and he gained the Unique Skill Pride. To alleviate his boredom, he monitored human civilization and destroyed any country engaged in warfare.

Guy joined forces with the Seven Angels of Origin in a three-month assault against the World-destroying Dragon, Ivarage. However, Ivarage managed to escape to the otherworld, leaving substantial damage in its wake.

After the battle, Guy surveyed the continent from above and spotted the Imperial Castle of the Super-Magic Empire, where he had been summoned. He decided to make the castle his home, believing it to be fate. The White Ice Dragon, Velzard, appeared and attacked Guy out of jealousy for his interaction with her brother. Their battle ended in a draw, and during the fight, Guy's power evolved further, granting him the Ultimate Skill Lord of Pride, Lucifer. Intrigued by Guy, Velzard decided to observe him from that day forward.

Thousands of years passed, and Guy, bored to the core, received visitors: Rudra, Velgrynd, and Lucia. Rudra, dropping any pretense of an honorable duel, demanded Guy to hand over all his valuables. Amused by the request, Guy accepted the challenge. Despite Rudra's immense swordsmanship and the support of his sister's Holy Field and Holy Blade spells, Guy analyzed and replicated his every move, becoming stronger as the fight continued. However, Rudra halted the challenge and named Guy, as he didn't want to fight a Demon Lord with a funny name. Thus, Guy was renamed Guy Crimson based on his red hair color. From that point on, the two engaged in daily fights with no clear winner emerging.

One day, Rudra proposed a change in their matches. Realizing that their direct battles would never lead to a resolution, Rudra suggested using their subordinates as proxies, with the winner claiming dominion over the entire world. Unfortunately, this ideal was not meant to last. Tragedies unfolded since the inception of the game between Guy and Rudra. Shortly after Veldanava and Lucia had their child, Milim, a terrorist attack occurred in the Nasca Kingdom, taking advantage of Rudra's absence. The attack, orchestrated by a warring enemy, resulted in the deaths of Lucia and Veldanava. Another tragedy befell Milim when her pet dragon was killed by a foolish kingdom. Enraged, Milim destroyed the country and awakened in the process. Guy intervened and battled Milim for seven days and nights, turning the once-bountiful fields into a wasteland. In the end, there was no clear winner, but with Ramiris' assistance, Guy managed to calm Milim down. These events plunged Rudra into deep depression, forcing Guy to continue the game to keep his friend from falling apart.
