Description
Suelecia Garcise Analeit, commonly called Sue, is the second princess of the Kingdom of Analeit and younger half-sister of Schlain "Shun" Zagan Analeit. Born in 841 to King Meiges and the queen consort, she grew up alongside Shun in the royal castle. Despite being a native of her world unlike her reincarnated brother and his classmates, Sue displayed prodigious talent from childhood, with stats rivaling reincarnated individuals. This resulted from emulating Shun's rigorous training during infancy, a period of rapid stat growth.

Sue has a petite stature, fair complexion, cyan eyes, and tailbone-length cyan hair styled with bangs and two feelers. Her personality centers on an extreme, unhealthy attachment to Shun, bordering on idolization and developing into romantic feelings. This manifests as yandere tendencies, including intense distrust and jealousy toward females near Shun, particularly Karnatia "Katia" Seri Anabald (reincarnated as Ooshima Kanata). Though Sue gradually warms to Katia superficially and consults her on romance, she privately maintains contempt for her as an obstacle. Her jealousy is toned down in the anime compared to the source material. Academically and martially studious, Sue excels in swordsmanship and magic, driven by her desire to emulate Shun.

Her magical abilities include Water Magic (her strongest affinity), Ice Magic, Wind Magic, and Light Magic. She is skilled enough with Light Magic to mimic Shun's signature affinity, a crucial factor in her later actions. Sue's combat training was overseen by former knight Klevea, whom she never defeated. She possesses Battle Divinity to accelerate reflexes, Magic Power Perception, and Magic Power Operation.

Sue's pivotal development occurs during the 856 coup in Analeit. After her half-brother Julius, the previous Hero, dies, Sue is present when Shun visits the king to discuss becoming the new Hero. Under orders from Shiraori and while seemingly brainwashed by Hugo Renxandt, Sue assassinates her father using Light Magic and frames Shun for the regicide, forcing Shun to flee. Hugo installs Sue's full-blooded brother Cylis as a puppet king, and Sue departs for the Renxandt Empire as Hugo's betrothed.

It is later revealed Sue only pretended to be brainwashed during the assassination. She cooperated with Hugo under her true master Shiraori, whom she first encountered when attempting to assassinate Hugo for targeting Shun during the Academy Arc. Recognizing Shiraori's overwhelming power, Sue submitted and became her subordinate. Sue views Shiraori as an "evil god," obeying out of fear while privately resenting her manipulative methods. Her primary motivation for serving Shiraori is the promise of being rewarded with Shun. She rationalizes that cooperating with Shiraori does not constitute betrayal of Shun, as her end goal remains securing him for herself.

Sue's relationships are defined by her fixation on Shun. She had minimal attachment to other family, including her father and brother Julius, whom she saw as obstacles to her closeness with Shun. Though distraught by Julius's death, she had prior knowledge of his fate due to her allegiance to Shiraori. Her mother entrusted her with political tasks like spying on her half-brothers to secure Cylis's succession. Sue's interactions with Feirune, Shun's familiar and a reincarnated classmate, are marked by chagrin due to Feirune's attachment to Shun.
