Despite refusing early maternity leave, she collapses on subway steps due to overexertion and is hospitalized. One month later, she insists Irie attend pregnancy classes with Kin and Chris, where she goes into labor. While Irie is forced to operate on Matsumoto, who is coughing up blood, Kotoko gives birth to a daughter named Kotomi.
