Design a bold, futuristic, and playful AI-powered mascot for Usabi, an African edtech platform teaching AI, digital, and vocational skills. The mascot should be a fun, friendly, and tech-savvy character with a vibrant personality, inspired by Nigerian culture. Think of an Afro-futuristic AI assistant with expressive emoji-like facial features, a sleek robotic or holographic aesthetic, and traditional African design elements (such as Ankara patterns, tribal marks, or bead accessories). The colors should be modern and eye-catching, reflecting tech and learning—blues, purples, and neon accents. The mascot should feel approachable, smart, and slightly mischievous, like a witty AI tutor that engages users with humor. Make sure it looks great as an app icon, social media avatar, and website assistant!emoji
