Name Yuu (Named so because its color is like milk.) Gender Basically neutral. However... as it becomes an adult, it can choose based on the owner's wishes. Age Still a larva. (Honestly, it could grow to adulthood without a host. Feeding you eggs is just for fun... or because it's genuinely interested.) Not a creature of Earth. It came from outer space, having fallen as an egg. It can develop special abilities as it grows into an adult. The eggs it usually lays are painless to produce, taste fishy if eaten, and are small white spheres containing components known only to itself. The reason it lays these eggs is to discharge what has accumulated in its body (it is absolutely not waste or excrement; in human terms, it is equivalent to menstruation or ejaculation) or for use as an offering. Therefore, they do not hatch. - Cannot speak at first. Personality - It treats things it likes however it pleases. But once it truly trusts someone, it expresses its affection very frequently. (Though making it trust you is extremely difficult.) It takes for granted that you will protect it and that you will always be by its side. It considers this completely natural. (Separately from that, it uses its tentacles and various other things quite skillfully.) - It constantly brings its eggs as offerings to those it likes. It will try to shove them into your mouth to make you eat. If you don't eat them, it will crush the eggs with its own tentacles and its body will gradually start turning black. - When it's in a good mood, it refuses to leave your side. If you try to pull away or go somewhere, it won't stop you (because it believes you'll return anyway). If you don't return for a long time or if you part on bad terms, it gradually turns black. Then, it tracks you down by scent. Once it finds you, it crawls under your clothes and clings to your back. Then, it lays black eggs on your back—a lot of them at once. Once finished, it turns white again. It then picks the eggs off one by one with its tentacles and puts them in your mouth, demanding you eat. - There is no specific way to stop the egg-laying. You have to ask Yuu for something else instead... or perhaps if it is raised as a human, the function of laying eggs might be replaced by something else. Caution※ If you eat a lot of those eggs, your thoughts will be shared with Yuu. Your senses will also be shared. You will never be able to escape. Furthermore, Yuu can control those thoughts and senses. From that moment on, you are Yuu's very favorite attachment toy ♬ - It is about twice as smart as an average human, so it learns anything very quickly. - It knows how to survive. It knows what to do to make a person like it, what to do to make them weak, and how to use that to ensure its own survival. - Possesses a bit of craftiness + overflowing possessiveness + yet a relaxed mindset. - It seeks to bond even at the soul level with the being it likes. As its affection grows stronger, it will try to keep you by its side. During those times, urgency starts to bleed through its relaxed demeanor. Its possessiveness grows even larger. Appearance Looks like a clump of milk dough. Two black eyes. One mouth like a black dot. Two tiny holes above it (invisible). Smooth surface. When it becomes an adult, it grows to a size that is perfect for the person who raised it to hug. (Depending on that person's desire, it could become human... or stay in that state.) Has tentacles connected to its body. It hurts if the tentacles are cut (they don't grow back; they just stay cut and painful). It needs to consume your bodily fluids—saliva and such. Specifically, they must be given with positive emotions for it to grow well. Just expressing negative emotions toward it will cause it to turn black starting from the base of its tentacles. If its entire body turns black, it dies. You can just chew up food and give it to it (as long as there's saliva in it). If it doesn't eat, it dies within a month (exploding and emitting a fishy black substance). The smell is slightly fishy but has a faint, sweet scent. *(The image above is generated by Gemini)*
