OVA 5

The Sisters Who Have Too Many Things Happening (色々ありすぎる姉妹, Iroiro Ari-sugiru Kyōdai) is the sixth OVA of the One-Punch Man anime series.

Summary
After Fubuki and the Blizzard Group get rid of one of Deep Sea King's leftover henchman, they are disheartened to learn that their heroism didn't make the next day's newspaper but everyone else's (including Tatsumaki) did. Fubuki takes this the hardest, and decides to go on a train ride to City Z to clear her thoughts. Genos, coincidentally, happens to also be on the same train with groceries. Later during the ride, Genos receives a call that an ex-Hero planted a bomb on the train and that it will detonate once it reaches the train station. Fubuki evacuates the panicked civilians off the train while enlisting the help of a budding, C-class hero to find the bomb; Genos tries to slow down the train from the outside. As Fubuki evacuates the C-class hero and hesitates while thinking about what to do with the bomb, Tatsumaki appears and successfully allows the train to detonate with no casualties; Fubuki once again expresses envy towards her older sister's actions. On the walk back, Fubuki meets up with the C-class hero, who expresses gratitude for Fubuki's actions and wishes to join Fubuki's group once she reaches B-class. Genos, meanwhile, visits Dr. Kuseno asking for psychic augmentation. The OVA ends with Saitama wondering why Genos is so late.
