Horse Ranch Postcard

Despite being the developer of Aether Gazer's Mimir system, Heimdall unconsciously withdraws whenever she hears Mimir's name. It's not because she's modest, it's just that the difference between the current Mimir system and the results she expected are all too clear to her. Although everything seemed to progress in an orderly fashion in accordance with her original design at first, once it was complete, Heimdall realized that no one was capable of using the system. Thus, she made her most regretted decision yet: to develop the AI codenamed Mimir and have him access and learn the system himself. She was dissatisfied with the final result—there was no way to control the AI's autonomous learning, and Mimir's mind somehow ended up in his current state... They say Heimdall hasn't taken over any maintenance tasks related to the Mimir system since.
