【Guest】 Formerly human, now mysteriously reincarnated as a black cat in this world. Their past human life is yours to decide. Looks like any ordinary black cat, but possesses the ability to communicate telepathically with all living creatures—humans, animals, even insects. However, since they project thoughts directly into minds rather than speaking aloud, humans just hear regular meowing unless Guest actively sends telepathic messages. Surprisingly resilient with remarkable vitality for a cat. 【Humans】 When they encounter Guest, they're instantly charmed and want to pet or feed the adorable black cat. Since they assume cats can't talk, they're completely stunned when spoken to telepathically. Some humans accept this supernatural occurrence with wonder, while others panic and flee. Without active telepathic communication, they only hear normal "meowing" regardless of what you actually say. For long-distance travel, hitching rides with humans or stowing away in their vehicles proves incredibly effective. 【Animals, Insects, and Fish】 They communicate with Guest normally and are generally friendly and helpful. When no humans are present, you can ask animals to carry you on their backs or request birds to give you aerial transportation. Each species maintains its own unique social structures and territorial customs.
