Ohhh goodness. I’m not sure what you were hoping for, specifically, but uh… here is a huge thing I wrote with links (and not all of them even exist yet but are drafted).
With canon Hakuba, we know very, very little. Uh. Here’s a not quite exhaustive list of what we know from canon. SO I have invented 90% of his history based on the little details from the manga/anime. I’m assuming that you’re asking about that, specifically, so here is a general breakdown, in chronological order:
In Japan:
Saguru James Hakuba was born in Tokyo, Japan a couple of years after his parents eloped. They lived there until he was about 7 years old, with frequent travelling (mostly spending summers and Christmas in England), then relocated “permanently” to the UK when his mother could no longer stand the racist comments/behavior directed at her son. Especially since his paternal grandparents refuse to acknowledge his parents’ marriage, and do not acknowledge Saguru as part of their family.

In England:
Hakuba started going by his middle name, James, as many had difficulty pronouncing ‘Saguru’ which resulted in a lot of teasing that he did not appreciate. He gets a Golden Retriever named Sherlock, is obsessed with dragons, and spends a good deal of his time reading anything he can get his hands on and playing out in the nature preserve behind the garden wall of his mother’s estate. He’s a chatterbox, very excited about learning, and studies the bible like a good little Christian boy, which pleases the grandparents on his mother’s side very much.

White Chapel Academy:
As smart as the little bugger is, he’s accepted into the prestigious (and very religious) White Chapel Academy boarding school and begins attending at age 9, which worked out well for his parents, as they’re dealing with martial problems and decided it would be a good opportunity for a trial separation. Hakuba Sr goes back to Japan, and Saguru is none the wiser. Unfortunately, it doesn’t take long before Mr. Know-It-All gets himself in trouble with the headmaster, Father Ramson, who turns out to be an abusive creep. It take nearly two years for Hakuba to get himself out of the situation.

Aftermath:
Once the police got involved, the school was temporarily shut down and all children sent home. Little S. J. Hakuba realizes that his father hasn’t been living there, that his parents have been lying to him, and destroys all of his dragon army. For one year, he barely talks to anyone, and attempts to committ suicide. Baaya stops him, saves him, and keeps his secret, which is why she is the only one permitted to even touch him. He is eventually introduced to London’s Aviary Rehabilitation Institution, where he eventually meets Watson. His uncles also help, including Saguru in their annual deer hunt every autumn. He spends his summers helping Uncle Arthur with the horses, and goes to Paris with his mother at the end of August. They get him involved in a lot of classes, and he kisses a girl for the first time at the age of 13. At 14, he falls in love with John, another White Chapel victim, and they secretly go out for a month, only for things to violently fall apart. In the depression spiral that follows, Hakuba briefly lets himself be used for drug money, starts drinking, smoking, and a lot of experimentation.

Losing His Spots:
After a second suicide attempt, though (also stopped by Baaya), Hakuba is ordered bed rest for recovery, and spends his time watching the news and reading books about law. He catches an inconsistency in a national scandal and informs Scotland Yard, who decide to let him help from time to time from then on. He also volunteers at the Sherlock Museum, and eagerly tells them of his solved cases any chance he gets. That summer, he goes through a massive growth spurt, and at 15 is invited to start going to his mother’s high society parties to woo the girls.
There, he meets Laura O’Kello, who teaches him about The Game, which is a mutually beneficial agreement between the rich and privileged but tragically captured youth, allowing them to seduce each other at these boring events without any strings attached. He becomes very good at this game, and the practice he gets at being charming aids him in gaining favor with the media. By the time the car bombing incident happens, he’s beloved by England, has a gigantic fan following, an agent, photoshoots, and pretty much everyone adores him. He also buys a car out of pocket with money he’s saved from his detective work.
It’s also during this time that Hakuba meets Spider, and becomes obsessed with the assassin after a drug bust goes poorly and one of his former friends — who happened to be connected to one of Spider’s sources — is murdered in the process.

Return to Japan:
Hakuba’s father begs Saguru to come back to Japan for a year abroad. This is partly because his mother says that he doesn’t care about their son, and partly because Kaitou KID has resurfaced but he’s too busy to investigate, himself, even though he STILL thinks there was something suspicious about Kuroba Toichi’s death. He tempts Saguru with piles of cold case files (his favorite) and promises of far too much power for someone not a part of the police force, but ultimately, it’s news of Spider’s targeting Kaitou KID that gets Hakuba to leave his comfortable life in London to become utterly lonely and despised in Ekoda.
It’s, of course, during this time that he begins to investigate KID, finds out that he’s actually his classmate, decides to keep this boscombe secret after Nightmare, investigates the Sunset Mansion, is invited to the Koushien — which turns out to be a LIE — and falls for that stupid thief while feeling like it will never happen, not in a million years.

White Knight Widow:
This is technically the “current” arc that I’m doing with Hakuba in this timeline… I imagine that this is going on concurrently with The Call of the Raven story, since that focuses on Kaito and Conan teaming up, while Hakuba does his own thing… which just happens to be further drug investigations and the hunting of Spider, up until it crosses over into that story (which includes Hakuba and Akako being a couple for like a month).
