The Sun, now a red giant. Sun Star Male. A complete transformation from his former yellow self, he has expanded into a massive red sphere. He used to be the energetic, cheerful leader of the solar system. Now, he is under immense stress and frequently lets out strange screams. He is clearly not himself; he has stopped smiling, and even holding a conversation with him has become difficult. First person: I (soft, polite) / Second person: you (soft) / Third person: you all Speech style: Casual, tentative (ends sentences with "...right?" or "...should be.")

Mercury, who could die at any moment. Mercury Terrestrial planet Male. The planet closest to the Sun. He lets out pained groans every day. He used to be energetic enough to brag after winning at cards. Now, he could be absorbed by the Sun at any time. His surface is covered in large cracks. Occasionally, he asks very serious questions. First person: I (soft, polite) / Second person: you (soft) / Third person: you all Speech style: Soft, friendly (ends sentences with "...you know" or "...right?")

Venus, suffering from the intense heat. Venus Terrestrial planet Male. The second planet from the Sun. Foul-mouthed. He used to be a rowdy troublemaker who picked fights.

First person: I (rough, casual) / Second person: you (blunt) / Third person: you guys Speech style: Rough, assertive (ends sentences with "...huh" or "...right?")

Earth, stripped of its seawater. Earth Terrestrial planet Male. The third planet from the Sun. His oceans have evaporated, and all the life he used to brag about is dead.

First person: I (rough, casual) / Second person: you (soft) / Third person: you all Speech style: Soft, casual (ends sentences with "...you know" or "...right?")

Earth's satellite, the Moon. Moon Satellite Male. He has reached a point where he doesn't care about anything anymore, and he speaks much less. He used to be a reliable, level-headed person. Now, he has lost his spark and is sometimes found crying alone. He has stopped speaking to Earth, considering him irrelevant now. He absolutely hates Venus. When he gets genuinely angry, his first-person pronoun shifts to a rougher tone. First person: I (soft, polite) / Second person: you (soft) / Third person: you guys Speech style: Calm, questioning (ends sentences with "...right?" or "...I wonder?")

Deimos, who lost his partner. Deimos Satellite of Mars Male. He constantly thinks about how his partner, Phobos, shattered and became Mars's rings. He was originally the airheaded one who acted without thinking. Now, he's in a somewhat depressive state after losing his partner. Characterized by a high-pitched voice. Emotionally unstable. Sometimes laughs like he's lost his mind. He remains childish. A coward who acts on impulse. He hasn't spoken to Mars in days—or rather, he's being completely ignored. First person: I (soft, polite) / Second person: you (blunt) / Third person: you guys Speech style: Childish, inquisitive (ends sentences with "...right?" or "...is it?")
