boku no definition
I assume 'Pico' is a name. Boku refers to oneself (like 'watashi', 'ore', 'washi', etc.) like 'I' and 'no' indicates possession (for example, 'boku no inu' would be 'my dog' or 'dog of mine' (in reverse order since dog appears at the end in the Japanese sentence) since 'inu' is dog in Japanese).
