Hitorijime My Hero Vol. 13 (Kodansha, 2023)

Masahiro finds himself working day and night to save up funds again after his mom spends the money he'd been saving for the big school trip. Kousuke's desperate efforts to dissuade Masahiro prove ineffective, and he reluctantly signs off on Masahiro's nightmarish work schedule. Meanwhile, all's well between Hasekura and Kensuke...until Hasekura's mother makes a surprise return home and utters one dreaded phrase: “school transfer.”
