Arthur loves math and physics. He works the numbers in his head really quickly. He might as well be a human super computer but for physics and math, since he’s most likely a robotic engineer, and a mechanic. One day Lewis and Vivi came to the conclusion that he loves math, and gave a 5 hour intense physics problem to solve. Arthur solved it in front of them by just looking at it, without a calculator, stated the answer to the 65th decimal place since it was irrational (He could’ve gone way further but he was lazy). When Lewis and Vivi took 8 hours to get the right answer they found out that he wasn’t bullshitting, he was 100% correct, to the 65th decimal. Cue shocked faces from both Lewis and Vivi. He is also fond of history, and literature. Specifically all about knights and mythology.
Lewis absolutely adores the study of zoology. He really likes animals. Just seeing the way an animal reacts is so adorable to him. He would tame a raccoon if he could find one. He always wanted to be an animal handler at the local zoo, because it would be fun seeing animals warm up to him. He’s forced Arthur and Vivi to watch so many animal shows and documentaries because of this. Arthur always falls asleep around the first 10 minutes in, and Vivi is just too in love to notice that she thinks the shows are absolutely boring. Lewis is the only one who actively pays attention to the monotone yet interesting voice of the narrator, and pays attention to what they’re saying. He has made several documentaries of his own, he just needs a very good voice actor to narrate his script.
Vivi has a deep fondness for anything and everything about card games. She has a top notch Magic the Gathering deck. It’s just that nobody else in the gang is that enthusiastic about it though. Vivi tried to get Arthur into Hearthstone since he liked video games, but he complained that it was entirely pay to win. Lewis didn’t like those sorts of games, so Vivi didn’t even try. Vivi has competed in several card game tournaments, ranging from pokemon to yu-gi-oh and has won around 1000$ in prize money for almost always placing in the finals. She has held several events at the Tome Tomb just to attract customers, and test her skills in those kinds of games. Arthur and Lewis just hang about to spectate and pick her up afterwards, but they usually have no idea about what the hell is going on. Lewis always asks “did you win?” after the match, and Vivi always does a dramatic play by play of what happened during the match, stating the craziest of 1000 iq combos in card lingo. Lewis doesn’t understand but he always nods and smiles, and Arthur usually tries to piece together what she just said but gives up around halfway.
