Man of Chaldea
Humanity accumulates experience, knowledge, and stories to pave the path they walk from the past to the future, allowing them to mature. A trivial conversation may have taken place in an hour. An invaluable friendship may have formed in a day. Glorious growth may have occurred over the span of a year. But nobody can perfectly recall it all. What remains is only the end result; the process is always forgotten.
In the long run, or even objectively, there was not much difference between the boy and humans. At the end of the day, his memory was updated. It returned to nothingness. White. The boy retained only what he needed. Twenty-three hours and fifty-five minutes lost every day. Any shining event of the day is bleached away. But there's five whole minutes of the boy's conviction....the will to resist the update allowed him to retain memories that should never be lost or forgotten.
And then the boy grew up. He collected only the information required in order to look like a "certain human." It never crossed his mind whether it was genuine or not, because it's simple for one to wish, believe, and vow for something. The one and only Grand Order that makes him close to humankind is the idea that "humans do good things."
