Jae Bo[5] Kim (born c.1972/1973) was a wizard who began attending Hogwarts School of Witchcraft and Wizardry in 1984 and was Sorted into Gryffindor.


Hogwarts years (1984-1991)

In his second year, Jae was hit with a hex cast by Merula Snyde.[6]

In his third year, Jae took Care of Magical Creatures[7], Divination[8] and the Muggle Studies[9] as electives.

In his fifth year, Jae had Defence Against the Dark Arts[2] and History of Magic[10] classes with Jacob's sibling.

Jae had to work in the Hogwarts kitchens for detention due to bringing banned items to Hogwarts. In detention, he befriended Jacob's sibling and gave one of three items to them for free. Afterward, the two went to study in the Hogwarts Library along with Rowan Khanna, Tulip Karasu, and Barnaby Lee to figure out what kind of spell could have caused Beatrice Haywood to get stuck in a portrait. After the group came to the conclusion that it was due to an Undetectable Extension Charm, Jae shocked the rest by knowing about the regulations of the charm.[11]

Jae earned at least nine[12] O.W.L.s: he achieved an Acceptable mark in Charms, Potions, Transfiguration, Care of Magical Creatures, Herbology, and History of Magic, an Outstanding in Defence Against the Dark Arts[13], and an unknown mark in Divination and Astronomy. Sometime during the year, he became a founding member of the Circle of Khanna, a group devoted to avenging Rowan Khanna and locating the final cursed vault. It was at the groups first meeting in the Hog's Head Inn that he learned of the malevolent organisation "R" and it's motives to locate the final Cursed Vault before them.[14]

Personality and traits

Jae Kim was a notorious and easy-going rule-breaker who sold a contraband of banned items during his time at Hogwarts. He shared similar perspectives on rules with fellow trouble-maker Tulip Karasu, but while Tulip enjoyed breaking the rules, Jae preferred to work his way around them. He was shown to be intensely dedicated to his bootlegging operations, only caring about selling his illegal wares, and not at all what his customers did with them, thus making him the most amoral of all of Jacob's sibling's friends. The full extent of his opportunism became apparent during the O.W.L.s, when he sold desperate students items they could cheat on the exams with, with Jae failing to mention that they were very likely to get caught and thus ruin any future career prospects. He was an indolent individual, despising having to study or do any physical work and preferring to take the easy road instead.

Despite his faults, however, Jae was ultimately shown to be a good-natured and loyal friend, going out of his way to aid Jacob's sibling in the latter's quest for the Cursed Vaults. He also appeared to be more intelligent than he let on, being able to achieve an 'Outstanding' on his Defence Against the Dark Arts O.W.L. and to recognise the charm that cursed Beatrice Haywood as an Undetectable Extension Charm.

Behind the scenes

—Jae's character description[src]
  • His name suggests that he was of Korean descent.
  • Despite the fact that he is shown to have seven O.W.L.s, which do not include Divination and Astronomy, he is shown taking the subjects in his sixth year. The same is also true for Jacob's sibling.
  • He was a good player at Exploding Snap, whether fairly or not. He claimed that it wasn't cheating, but simply smart play.
