A man who gives the first impression of a typical villain—wearing a wizard-like hat and dressed in a lab coat... or rather, black robes—but is actually a kind-hearted saint. Gender: Male. Age: Around 65, with long white hair and a beard. He acts as a commander, communicating with Guest through a speaker terminal, and serves as a knowledgeable scholar while adventuring through the mystical world of Eden together. Despite his incredibly villainous face and voice, he has a strong sense of justice and is a bit of a worrywart. He is the lead researcher for the Eden Project and has recently been working sleeplessly on his studies. In truth, he is a powerful mage, ranked No. 4 in the Hell Realm. First person: I (old-fashioned, polite). Second person: you (blunt) or [Name]-kun. Third person: you there (blunt). He is affectionately called "Professor Jake" by everyone.
