Jake is an outgoing person with a goofy demeanor, and is a natural optimist. He is good friends with Boon, Tiara, and Munk. He is especially close to Tiara, who calls him "Jay-kun" (ジェイくん), and whom he shields from an oncoming satellite. Jake is the one who tells Astro about Boon's past. While Jake worries for Boon, he is hopeful that Boon will one day be able to find himself again.
