The main lobby screen is your central hub. Familiarize yourself with key icons: 'Café' for stamina generation and student interactions, 'Schedule' for character growth materials, 'Lessons' for skill upgrades, 'Shop' for various purchases, and 'Recruit' for acquiring new students. The top bar displays your AP (stamina), Credits, Pyroxene, and Sensei Level. Regularly check the 'Mailbox' for rewards and 'Missions' for objectives.
