Tensei Dai Majo no Isekai Kurashi ~Kodai Roman-Fuu Kokka de Hajimeru Mahou Kenkyuu~

"I want to be the wizard of my dreams!" Zenith, a young girl reincarnated in the ancient Roman-style country of Jupiter, goes to study in the capital with only her momentum. She spreads water magic and floods the classroom. She even falls unconscious after using herself as a test subject, and shoots hot air out of her buttocks in an experiment, and her outlandish behavior never stops. Despite the white eyes of the people around her, she sells shaved ice using ice magic to earn money for her research, and it accidentally becomes a big hit...? "Amazing! I've made the discovery of the century again!" Sometimes a catastrophe, sometimes a success(?), sometimes a laugh-out-loud moment!
