Ramshackle[]
MC[]
During Book 3, Jack was helping MC with trying to fulfill the contract MC made with Azul despite Jack feeling displeased with the fact that MC made a deal with Azul, knowing the housewarden must be scheming something. He also offered MC to stay over at Savanaclaw after their eviction from Ramshackle Dorm, and asked Leona to let MC (and Grim) stay over at their dorm.
Heartslabyul[]
Riddle Rosehearts[]
Jack respect Riddle for his achivements in school, his magical skills and efforts as a housewarden.[1]
Savanaclaw[]
Leona Kingscholar[]
Jack was intitially impressed by Leona's strength and performance during a Spelldrive tournament, playing a role in Jack's decision to come to Night Raven College. But when he found out that Leona was using dirty methods trying to secure victory, Jack was disapproving of his actions. He believes Leona is capable of doing better, and win fairly.
When Jack was being picked on by his upperclassmen during spelldrive practice, Leona came to his rescue, which confused Jack. Though he's slightly displeased by Leona's treatment of him, Jack also appreciates his help and apologizes for the trouble. After witnessing Leona's showcase of his magical abilities and leadership skill, Jack begins to consider him an incredible housewarden. He also wants to have a match against Leona at his strongest one day.[2]
Ruggie Bucchi[]
Despite disapproving Ruggie's actions before the Spelldrive tournament, Jack developed a strong admiration towards Ruggie, as he finds Ruggie's loyalty towards Leona impressive and worthy of respect. He wants to prove himself to Ruggie to earn his respect and help him in any way he can.
One time Jack overheard Ruggie's conversation about how he couldn't find one of Leona's necklaces as it was snatched by a crow, and Jack decided he would help Ruggie to find it. He ended up climbing every tree to check crow's nests, and successfully found the necklace, saving Ruggie from possible trouble. Ruggie asked if there's anything Jack would like in turn, to which Jack asked Ruggie to take him under his wing and mentor him. However, Ruggie refused it, but told Jack that he would accept him as an underling.[3]
Pomefiore[]
Vil Schoenheit[]
They're from the same hometown, and Jack used to greet Vil whenever they met in public. The two seem to share a friendly relationship, and they often go on morning jogs together. They went to the same middle school for a few years and played together before Vil attended Night Raven College. [4]
It is revealed in Book 5 that they met as kids when Vil had just moved to the same town as Jack. Jack saved Vil from some bullies who associated Vil with the terrible villain he played on a TV drama claiming they were going to punish Vil on behalf of the hero of said show; a feat they claimed would be simple since Vil looked frail and easy to overpower. Before they got close enough to him, however, Jack lunged at the bullies who ran away frightened after seeing it's Jack. Jack asked Vil if he's okay, to which Vil replied that he takes boxing and fencing and did not need to be rescued. Jack apologizes, but Vil thanks him for what he did regardless, claiming he is used to "stupid kids that cannot separate fiction from reality". Jack tells him he doesn't have a TV so he doesn't quite get it, but the fact that he moved some kids into hating him this much must mean Vil is a pretty good actor. This seems to cheer Vil up, who tells him next time he'll make sure to play the lead so he can move those kids to tears with his performance instead.
Epel Felmier[]
Jack And Epel are classmates in the same homeroom 1-B. The two have a mutual respect to one another as they would say only positive things about each other to their classmates and seniors. Among all the first years, they are able to get along without yelling at each other, instead speaking respectfully and hold a regular conversation. Jack and Epel are commonly walking together like during the freshman day to pick clubs, and Jack only followed the other freshmen to tour the sports clubs on Epel's suggestion. [5] Despite their camaraderie, they will tease each other like all the freshmen do with each other, such as Jack telling MC to pass a message to Epel to not mess up at the SDC as he was given a ticket by his homeroom classmate to see the show. [6] The only disagreement the two have been seen to have is whether apples or pears are better, Epel having grown up on an apple farm and Jack raised on pear compote since he was little. They will be saddened when MC picks one over the other during Port Fest at their waffle stand. [7]
Diasomnia[]
Malleus Draconia[]
Much like the other students in Night Raven College, Jack is cautious of Malleus for his power and reputation, but he also respects Malleus as a powerful Spelldrive player.
