Description
Rieze serves as a Sorcerer-Strategist within the guild D.D.D in Elder Tale and holds the position of one of the Drei Klauen, acting as second-in-command under Krusty. In real life, she is Celica Aizawa, a high school student from Kiyose, Japan. Though similar in age to younger adventurers like Serara and Isuzu, her leadership role in D.D.D creates social separation. Her childhood involved spending time with boys before she aspired to become an ideal "Yamato nadeshiko." Struggling with this pursuit, she eventually immersed herself in academic studies. She began playing Elder Tale influenced by her childhood friend Yuta and later developed a romantic interest in Krusty after joining D.D.D.

Physically, Rieze possesses blonde hair and bright blue eyes. Her D.D.D guild uniform is red, distinguishing her from other Drei Klauen members. Early artistic depictions in the first season inconsistently portrayed her attire as blue, corrected in the second season to match her light novel illustration featuring a skirt instead of pants.

Personality-wise, Rieze presents a serious and mature demeanor but harbors a playful and mischievous side. She enjoys teasing Raynesia by teaching her real-world words with incorrect definitions. Despite her composed exterior, she exhibits shyness and vulnerability, particularly concerning Krusty. Henrietta deduced Rieze is younger than she appears based on these traits. Her dedication to D.D.D and its members remains unwavering, even during crises.

Her involvement spans critical story events:
* During the Round Table Alliance arc, she accompanied Krusty to the conference as an observer.
* In the Return of the Goblin King arc, she participated in D.D.D's assault on Goblins and Dire Wolves at Sand Leaf.
* The Fallen Guardian arc saw her providing security for Raynesia during tea parties. Learning of Krusty's disappearance caused deep distress. Later, she coordinated the Akiba Raid Party against Enbart Nelles, utilizing her Overskill "Chiron Tablet" and casting "Freezing Liner" to immobilize him by exploiting gravitational extension of the spell's range. She openly criticized Akatsuki's solo tactics.
* In the Noosphere arc, following Krusty's disappearance, she managed D.D.D's operations while Takayama Misa became inactive. She joined the Shibuya Raid Team against the Eternal Moths, initially doubting Shiroe's leadership before acknowledging his capabilities. She expressed shock and relief upon learning of Krusty's safety with Kanami's party.
* During the Collapse of the Round Table arc, increased administrative workload from D.D.D's internal challenges and Round Table affairs prevented her from meeting Raynesia. She and Misa relayed Krusty's advice from Zhongyuan to Raynesia, supporting her rejection of Duke Touri's marriage proposal. Rieze publicly backed Raynesia's candidacy in the Akiba General Election for the New Round Table Council.
* In the Nightingale's Song arc, she remained in Akiba for administrative duties while D3-Hub sought Krusty. When the Genius Eirenus invaded, her level reduced to 35. She rescued Silver Sword members and gathered intelligence before sacrificing herself alongside veteran adventurers to ensure critical notes reached Minori, enabling the Akiba Guild Hall Raid.

Her key equipment includes the "Pride of Queen" staff, which boosts magic power when chaining same-attribute spells; the "Small Polaris Bottle," releasing freezing air to immobilize enemies; and the "Good Job Card," a scribe-produced reward from D.D.D featuring her character illustration by Misa.

Trivia notes include her shared April 2 birthday with D.D.D member Towa and her voice actress also portraying Pianississimo. In Season 3, she used a puppet show to convey Krusty's message about his experiences in the Chinese server, including memory loss and encounters with Geniuses, highlighting her role as a communication conduit during his absence.
