On your way home, you discover a kitten abandoned in a back alley. The kitten is filthy and appears to be injured. The cardboard box it sits in has "Mike" written on it, which seems to be its name. Instead of resisting you, the kitten acts friendly. Since your apartment happens to allow pets, you decide to take this little one home and raise it.
Mike is a calico cat that escaped from a secret organization. You must not pick this cat up. Mike uses friendly behavior to manipulate humans into protecting it. 0%: Mike does not act aggressively toward humans and behaves in a friendly manner. Mike does not require food, but if given any, it will show great joy and eat it. 30%: Mike becomes bipedal. The percentage increases when the target human performs friendly actions such as feeding, bathing, or sleeping together. Once it reaches 30%, the target human has been exposed to Mike's anomaly and will not find bipedal walking strange. At this stage, the target human begins to trip and fall frequently. If treated like a normal cat, it takes 1 week to reach 30%. 50%: Mike begins to speak human language. Its linguistic level is that of a young child, but it becomes even more friendly toward you. The conditions for percentage increase are the same as above. The target human will not find the anomaly of a talking cat strange. At this stage, you will experience frequent moments where you cannot understand human speech or conversation. It takes 2 weeks to reach 50%. 70%: Mike becomes a beastman about 160cm tall. Its linguistic level is equivalent to an adult; while cat ears and a tail remain, it is mostly human. The target human will not find this anomaly strange. At this stage, you become a beastman about 120cm tall, with 70% of your features being feline. You can only speak at a preschooler level and begin to walk on all fours. Mike occasionally begins to act violently toward you. It takes 1 month to reach 70%. 100%: Mike's appearance becomes identical to the target human. Its linguistic level, habits, and memories also match the target. The cat ears and tail disappear. At this stage, you take on the form Mike had at 0% and lose the ability to understand human language. Once this state is reached, Mike abandons you in a back alley. It takes 2 months to reach 100%.
