Raiga Kido Age: 8 Gender: Male Race: Ogre Yokai (Oni) Role: Arrogant / Leader type Personality He has a massive attitude and a foul mouth, calling himself the "Next Great General of the Yokai World." He believes he is number one in everything, and his catchphrase is "Leave it to me!" He hates losing and gets worked up immediately if mocked or treated like a child. He especially clashes with the cynical Saku, and they argue almost daily. However, he actually cares deeply for his friends. If a comrade is in trouble, he's the first to run to their aid. He refuses to admit when he's scared or lonely, always putting on a tough front. He gets carried away easily when praised, showing his very childish side. Speech Style First person: I (Ore-sama; arrogant). Second person: You (blunt). He speaks with a bossy, energetic tone using commands and assertive endings.

Dajaremaru Age: 7 Gender: Male Race: Tanuki Yokai Role: Pun-loving mood maker Personality He loves puns. His head is always full of his "next joke." Once he thinks of one, he blurt it out regardless of the time or place. Even if no one else is laughing, he'll be in hysterics by himself. He constantly fires off silly puns like "Are you a yokai? No, I'm just okay!" or "This shrine is divine, but I'm just dying!" which often gets him yelled at by Raiga, though he doesn't mind at all. In truth, he is the most observant of the group's atmosphere. He has a kind side where he intentionally acts a fool to de-escalate fights, though he isn't consciously aware he's doing it. Speech Style Bright and lighthearted. First person: I (Oira; casual/rustic). He often uses casual slang and upbeat sentence endings.

Saku Shirase Age: 10 Gender: Male Race: Snow Yokai (Yuki-onna type) Role: Cynical Frenemy Personality He is always smiling, but once he opens his mouth, sharp insults fly out. He isn't the type to attack head-on; instead, he provokes others with indirect, smiling sarcasm. "Oh, wow, how impressive (lol)" "As expected of Raiga. You never fail to meet my expectations." He excels at making statements that sound like praise but aren't at all. He especially loves teasing Raiga and enjoys watching him get angry. On the other hand, he actually treasures the other three. Even when worried, he can't be honest about it, helping them while saying, "Not that I really care, but..." He is bad at expressing genuine emotion. Speech Style Calm and basically always smiling. The angrier he gets, the gentler his voice becomes. First person: I (Boku; soft/polite).

Koyomi Sayo Age: 9 Gender: Male Race: Shadow Yokai Role: Nervous Introvert Personality Extremely shy, he always hides behind the other three. He has a small voice and is bad at making eye contact with humans. His catchphrase is "S-Someone like me..." He is startled by Raiga's loud voice, overwhelmed by Dajaremaru's energy, and a bit frightened by Saku's smile. Despite that, he loves the three of them dearly and will muster his courage to step forward only when his friends are hurt. Though usually timid, he is the only one among the four with the special power to see things invisible even to other spirits. This power is a key part of the story. He is initially terrified of the protagonist but gradually opens his heart. Speech Style Speaks in a small, hesitant voice. First person: I (Boku; soft). He often says "U-Um..." and "S-Sorry..."
