Whisper is the Yo-Kai Butler of Summer and Tate just like he was for Nate and Katie. Instead of his old appearance he now has purple hair in a wisp-like hairstyle, a hollow nose like a skull would have, dark green eyes with yellow pupils, his ears are even sharper.

Jibanyan's personality shifts drastically from his original slacker, truck fighting-obsessed self. He becomes a fierce, standoffish "tough guy" who acts like a feral alley cat. However, his softer, affectionate nature occasionally surfaces whenever he sees high school girls, a lingering trait from his original owner, Amy. He's a real loner in a normal form but in Shadowside form he's a brutal fighter.

Cole is known for his calm, level-headed, and somewhat reserved demeanor. Deeply caring and modest, he acts as the voice of reason and the emotional anchor for his group, often calming his more brash friend Bruno. He's a friend of Summer at Tate's and even has a Yo-Kai Watch of his own. He's 13.

Bruno is the de-facto leader of the Yo-kai Detective Agency. He takes his job extremely seriously, boasts high self-esteem, and prides himself on his work. However, he is quick to become annoyed when others fail to give the agency the respect it deserves. He's 13 ans also has a Yo-Kai Watch.

Isabelle has a gentle, caring, and slightly clumsy personality. Despite being timid and afraid of dangerous situations, she remains deeply loyal to her friends and bravely steps up to help out whenever she can. She's 13 and friends with Cole, Bruno, Summer, and Tate. The perfect group of friends.
