Background / History

Chen Mu was recognized as an unprecedented young genius at sixteen: his intellect was considered comparable to Herta's despite having neither de-aged nor possessed a connection to the Aeon of Erudition. At Herta's recommendation, he met the Erudition and was personally admitted into the Genius Club. 1

Before his combat capabilities became known, Chen Mu was widely regarded as an ordinary human with no Aeon powers and was even considered weak in battle. His scientific accomplishments and unusual ability to meet Aeons nevertheless made him a major figure across the universe. 21 23

Chen Mu later joined the interdimensional Chat Group as a researcher. He initially described himself as an “ordinary person,” but quickly gained the members' trust by helping Kochou Kanae and explaining that his knowledge of their worlds came from novels, manga, anime, and games in his own world. He rejects the idea that they are merely fictional, instead calling it an exchange of information between worlds. 3 5 11

Although he has encountered several Aeons, Chen Mu has neither received a Path nor gained an Aeon's favor. He has also stated that he has no desire to become an Aeon himself. 44 98

Appearance

Chen Mu is a tall, exceptionally handsome young man whose calm bearing and distinctive aura cause others to overlook his youth. A photo of him at twenty-seven or twenty-eight was described as more mature, while his present appearance is considered more boyish. 110 133 143 193

• Possesses a composed, refined demeanor despite his age. 143 193
• Frequently draws attention for his appearance before others learn of his achievements. 80 193 211
• His presence has been described as both ordinary and dangerous by Athena. 118

Personality

Chen Mu is modest to the point of repeatedly insisting that he is an ordinary person, even when his inventions and combat feats make that claim difficult for others to accept. He is patient with the Chat Group's teasing and often redirects conversations rather than indulging the attention directed at him. 3 5 11 173

He is direct when honesty is necessary. Rather than conceal his foreknowledge indefinitely, he told the group how he knew of their worlds and stressed that future events could change through outside interference. 11

Despite his immense capabilities, Chen Mu is not indiscriminately self-sacrificing. He considers himself a good person rather than a saint, chooses whom he will go to great lengths to help, and respects boundaries such as refusing to enter Xianzhou territory without permission. 179 184

Formal social situations exhaust him, but he remains courteous and approachable in professional settings. He is also prone to teasing people he knows well, particularly Asta and Yor. 8 110 132 142
