Hajimetchi looks like a green flower bud with orange at the tips. He has yellow cheeks and four strands of hair on his forehead. He wears blue clothing with two light blue buttons.
Hajimetchi wants to learn the piano. He admires Smartotchi and Pianitchi, who care about him and help guide him in his efforts. He is playful and mischievous like most other kindergartener Tamagotchis, but he gets frustrated and loses confidence easily.
はじめ Hajime is the Japanese word for "beginning", which could refer to the fact that he is starting to learn the piano, as well as his appearance resembling a flower starting to bud.
