Description
Marcus Lithos is the user of the Azoth Sword and an original character created for the anime adaptation. He originates from a wealthy and aristocratic background, but his life changed dramatically after being involved in an accident that left him paralyzed. This physical limitation drives his primary motivation: to obtain and wield the Azoth Sword in the hope of curing his condition and restoring his mobility.

Outwardly, Marcus presents himself as calm, composed, and affluent, carrying the demeanor of an aristocrat. However, beneath this polished surface lies a deeply unstable inner world. His past trauma and the betrayal he experienced have left him psychologically fractured. He yearns for genuine human connection, but this longing manifests in a troubling way as he begins to simulate a family life, blurring the boundaries between reality and fantasy. This tendency reveals a fragile grasp on his own identity and circumstances.

In the story, Marcus serves as a supporting figure within the organization known as Shoshidai, which is tasked with collecting and containing cursed weaponry. He is first encountered alongside Miura when they ambush Miki after she acquires the Azoth Sword. Following this confrontation, Miki takes Marcus to Shoshidai headquarters, where he becomes more deeply involved in the organization's operations. He is later sent on covert missions, such as infiltrating a location to retrieve an ancient weapon, demonstrating his role as an active agent despite his personal struggles.

Key relationships include his connection with Miki, who escorts him to Shoshidai, and his partnership with Miura, with whom he initially works to seize the Azoth Sword. Marcus also develops a romantic relationship with a woman named Aya, though he harbors a sense that something is not right even during their time together, hinting at unresolved inner conflict.

Throughout his arc, Marcus grapples with the consequences of his paralysis and the power he gains from the Azoth Sword. His development is marked by a tension between his desire for healing and the unstable psychological effects of his trauma. By the second part of the series, he continues to carry out missions for Shoshidai while confronting the dissonance between his simulated happiness and the reality of his condition.

As a Chrysalis, Marcus possesses the ability to wield the Azoth Sword, a cursed weapon that grants its user significant power. His role as a sword user places him among the individuals who have bonded with such weapons, making him both an asset and a potential threat as he navigates the dangers of losing himself to the weapon's influence.
