Therese Alexanderite, also known as Terisu Arekisandoraito, is a member of the Jewel (Shoujin) race, distinguished by gemstones integrated into their bodies. Her most prominent feature is a gemstone set on her forehead, usually hidden beneath a tiara when she travels beyond her home world. She possesses light blue or aqua-green braided hair and light blue eyes; both hair and eyes shift color during spellcasting, often turning red when she employs jewel-based magic. Her skin is white and ivory-like, and she commonly wears large gemstone-studded bangles on both wrists. Her personality is typically graceful, gentle, and courteous, displaying deference in most situations. However, encountering finely crafted jewelry or accessories triggers intense excitement and passionate behavior. This fascination extends to admiration for expertly made items, leading to unconventional actions like attempting to sway enemy Jewel race individuals by displaying accessories. She holds deep reverence for skilled artisans, especially Naofumi Iwatani, whom she addresses as "Master Craftsman" after witnessing his work. This devotion sometimes causes friction with her companion, L'Arc Berg, who perceives potential rivalry. Her abilities focus on harnessing magic through gemstones and jewelry. As part of the Jewel race, she communicates with gemstones to access their energy, with refined accessories significantly amplifying her power. When equipped with three accessories crafted by Naofumi Iwatani, her magic reportedly reaches levels comparable to a Legendary Hero. Her repertoire, primarily "Shining Stone" techniques, includes: * **Elemental Attacks:** "Ball of Flame" (targeted fire projectiles), "Showering Thunder" (lightning strikes), "Shooting Star Rain of Fire" (meteor showers), "Karma Fire" (lava waves), and "Blizzard" (ice tornados). * **Support Magic:** "Protection Shatter" (reduces enemy defense), "Hardened Protection" (boosts ally defense), "Paralysis Wing" (immobilizing butterflies), "Slumber Smoke" (induces sleep), and "Silent Ocean" (neutralizes oceanic vortices). * **Utility Spells:** Unnamed illusion magic for disguise and verbal translation magic facilitated through L'Arc's scythe. She also possesses notable physical strength, evidenced when managing an intoxicated L'Arc. Her capabilities extend to combination techniques like "Thunder Rain Flying Circle" (electrified scythe disc with L'Arc), "Burning Disc" (fire wheel with L'Arc), and "Reverse Burning Snow Moon Flower" (flame squall with Glass). Key relationships define her narrative role. L'Arc Berg is her primary companion; their bond exceeds friendship though remains unacknowledged as romantic. Tension arises when her enthusiasm for Naofumi's craftsmanship surfaces, prompting L'Arc's concern about abandonment. Her interaction with Naofumi Iwatani centers on mutual craftsmanship respect; she actively seeks his creations and provides strategic support in battle. She establishes cooperative alliances with Raphtalia and other members of Naofumi's party during interdimensional conflicts. Her background involves traveling across dimensions with L'Arc Berg. Initial engagements position her against Naofumi's group to protect her world, employing subterfuge like appearance-altering illusions. Conflict shifts during confrontations with Kyo Ethnina, where shared threats forge an alliance with Naofumi. Post-collaboration, she reconciles with Naofumi's faction and participates in joint operations, financing escapes by selling concealed gems. Narrative continuities diverge: web novel iterations conclude with her demise during Wave assaults, while light novel adaptations attribute her survival to protective accessories crafted by Naofumi. Her jewelry expertise serves tactical functions, including appeasing hostile Jewel race entities.
