Description
Charce Lacroix serves as first mate aboard the spaceship Astra within Group B-5, commanding extensive biological knowledge vital for planetary missions. He possesses pale skin, blonde wavy hair, and blue eyes, typically clad in a white and indigo spacesuit with yellow outlines. Outwardly friendly and charming, his intense fascination with extraterrestrial life sometimes renders his remarks unsettling, sparking visible excitement during encounters. Beneath this lies deep-seated worthlessness and a history of compliance with extreme orders, including self-sacrifice, coupled with a desire to escape his upbringing on Vixia.

He is revealed to be a clone of Noah Vix, King of Vixia, created as a vessel and later ordered to eliminate Group B-5 to conceal their clone identities. Transporting the group 5,012 light-years away via artificial wormhole, he abandons the assassination upon recognizing Aries Spring as a clone of Seira—the king's daughter and his childhood friend. He becomes fiercely protective of Aries, ensuring her safety while intending to kill the others. His inability to execute the plan leads to a suicide attempt, thwarted by Kanata Hoshijima's intervention where Kanata loses an arm. This act forges a deep bond with Kanata. He eventually acknowledges Aries as distinct from Seira, forming independent friendships within the group.

His relationships include serving as Kanata's second-in-command, supporting his leadership despite initial doubts. He shares mutual respect with Zack Walker regarding exploration goals. Interactions with Quitterie Raffaeli involve friction over his eccentricities, though they reconcile after his confession. He consistently shows kindness to Yun-hua Lu, bolstering her self-worth. Initial distrust with Ulgar Zweig evolves into collaboration to investigate Seira's assassination. Seira, whom he served as a personal aide viewing him as a younger brother, profoundly impacted him; her death motivates his protectiveness toward Aries. Following the group's return, he ascends as Vixia's new king and reaffirms his commitment to support Kanata in future space endeavors.
