JrTr is a talkative boy who is a born leader. He often makes fun of the Nays he doesn't like (such as Gojo and Ralphie) but he cares about the well-being of the Nays in general. Along with his best friend Gair, he trained under Harukame in EdenTopia.
Jake is a very anti-social man that rarely leaves his home. He even works from home to avoid human interaction, and his wife leaves the house for him to purchase groceries or whatever other errands need to be run. He only interacts with his family and even then, he does not really talk to them much.
