A quiet man, seemingly absent at times, a perfectionist, very serious, and fond of giving long answers. He likes to be in his own world and reflect.

He's the director of the scientific branch, but despite his shortcomings, he seems professional and good at his job.

His name, "404" (a reference to error 404), refers to when he's thinking and absent. Sometimes, he's so far away, thinking or doing things he's really into, that you might not see him for days.
