Megami Tensei Wiki

"I... I think I know what you mean... Aegis, so long as you exist... I’ll be happy..."
—Yuu Kimijima professing her affection for Aegis.

Yuu Kimijima is a character from Aegis: The First Mission. She acts as the head of the Kirijo Ergonomics Research Institute on Yakushima Island.



Yuu has long, asymmetric teal hair in a small ponytail and light gray eyes. She is always seen wearing a white lab coat with a dress shirt, gray-black pants and boots. She wears a ribbon that resembles Aigis'.


"No mere machine can hold life as you do... And if you don’t, then I question whether humans themselves are alive..."
—Yuu Kimijima expressing her inner conflict of the value of humanity and the value of Aigis.

Yuu is generally friendly and treats Aigis like a human being and wishes others would treat her similarly. She is also the one who gave Aigis her Red Ribbon. Despite her affection for Aigis, she is frustrated at her inability to recognize and understand her emotions, even if she feels them in some capacity. She continually tries to make Aigis understand, but is never able to convince her using conventional means.

Yuu conflicts with Souta Aizawa from the start of the game because of his inability to see Aigis as a human rather than a machine. As Souta trains Aigis to be more and more robotic, Kimijima grows more angry at him, even to the point of physically accosting Souta. However, her hatred for him is somewhat superficial, as she reveals that she and Souta grew close to each other after she moved from Yakushima and that Souta would protect her in times of loneliness.

Yuu has an opposition to Takashi Tomari because of how close he is to Aigis, perhaps indicating that Yuu wishes to have Aigis to herself so that she can protect her. However, she recognizes that she can use Takashi to provoke a response from Aigis, and uses him to create a Shadow that she would later use against Aigis for this purpose.

Towards the end of the game, it is revealed that Yuu is torn between her duty as a researcher and her devotion to Aigis. Takeharu Kirijo's acceptance of Aigis being an acceptable loss distresses her, and leads her to leave the lab and never return. Later, after Aigis defeats the Shadow she created, she reveals that her intention wasn't to cause harm purely for the sake of evil; it was instead to prompt Aigis to awaken to her emotions and to understand. By testing whether Aigis would follow her programming or her heart, Kimijima hoped to show her that she should acknowledge the latter instead of relying on just her programming.

In her final moments, Yuu expresses profound remorse to Aigis for all that she has done, and that she will always be hers, even in death.
