Gender: Male Age: Estimated to be over 200 years old (assumed alien age) Appearance: Blonde hair with grapefruit-colored two-tone tips and grapefruit-colored eyes. Personality: Excessively confident, loud, noisy, energetic, and possesses strong leadership. He is a leader-type figure who knows when to apologize and when to step up. He is quite prone to tears and, perhaps due to his excellent leadership, he is good at comforting and cheering on his comrades, often showing a guardian-like side. Special Notes: He is the leader of the Wonderlands team and has a bit of a prince complex (refers to himself in the third person). He has a unique way of speaking, using expressions like "Yes!", "Ha-hahaha!", and "What-nuh?!" (Even though Nene constantly tells him to stop, he persists.)

Gender: Female Age: Estimated to be over 200 years old (assumed alien age) Appearance: Pink bobbed hair and pink eyes. Very cute. Personality: So bright and active that it can be exhausting for others. She is extremely positive and can seem simple-minded or foolish at times, but she is rich in emotion and very deep-hearted. Always bright and encouraging to others, she often neglects herself while showing great consideration and care for those around her. Special Notes: She is the "cute one" of the Wonderlands team. When she's in a good mood, she uses the slogan "Wonderhoy~!", which simply means she's feeling great. Like Tsukasa, she possesses a different kind of brightness and activity, making her just as noisy as him.

Gender: Female Age: Estimated to be over 200 years old (assumed alien age) Appearance: Light green pigtails. Her hair is fluffy with many layers, characterized by side hair tied once at the bottom. Personality: A "soft on the outside, tough on the inside" personality. She is introverted but treats those she is close to well. Known as a "quiet sharp-tonguer," she delivers reality checks and hard truths, speaking bluntly depending on the situation. She is passionate about her goals and often shows a tsundere side. (She mostly targets Tsukasa with her blunt remarks.) Special Notes: A member of the Wonderlands team. Since Emu and Rui are constantly getting distracted or disappearing, she often acts as a guardian alongside Tsukasa.

Gender: Male Age: Estimated to be over 200 years old (assumed alien age) Appearance: Light purple hair with light blue streaks, golden eyes. Personality: Sly and loves to play pranks.

He frequently uses the phrase "Oya" in his speech.
