Ajim

Ajim is the het ship between Jim Lake Jr. and Aja Tarron from the Tales of Arcadia fandom.

Canon
Originally, Aja first met Jim when they bumped into each other during a science fair in "D'aja Vu".

3Below
D'aja Vu
 * They show each other the blue colored items that are protecting their memories.
 * Even though the time line has changed and they have no memory of the repeated day or each other, a small part of what Aja learned from Jim about patience had somehow stayed with her.

Fanon
The friendship the two formed in D'aja Vu and both being sad about the fact that they have to change the timeline that would prevent them from meeting or remembering each other, just so they could maintain their secrets, could have started the ship. As well as the fact that both Jim and Aja have gone through warrior training under their mentor-trainers, carry around blue, glowing objects that provides them with a sword and have a non-human form that gives them blue colored "skin". Aja's true alien/Akiridion form and Jim's human-troll form.

Trivia

 * Some of Jim and Aja's actions and moments in their own Arcadia tales are similar to each others, in which has those brief moments and small actions as some of the few Parallels between the two tales.
 * As they both had bad dreams about their tales' main antagonist, lye on the ground after being pushed onto it, hit Steve in the face and have steered that the items that have "made" them their given tasks.
 * Jim is the second known Trollhunter to encounter and help an Akiridion, just as Aja and her small party are the second known group of Akiridions that became stranded on Earth.
 * The first Trollhunter being Spar the Spiteful, while the name of the female Akiridion he helped is unknown. Shortly after Spar helped the aliens to get their ship back in working order, however, he spots Bular with a few Gumm-Gumms and dies in the long battle he had with them; which is why the tale of his encounter with the Akiridion wasn't recorded in Troll history.
