The First Shopping Trip! The First Packed Lunch! The First Heartbreak! Huh?.After school, Eri decides to head for the supermarket, going after ingredients for nikujaga (beef and potato stew) following Mikoto's tips. The next day, Tenma decides to make use of the idea and has Yakumo make two lunchboxes with curry, one of them for Karasuma, so she can get next to him. However, she makes a mistake and takes Yakumo's rice instead. Karasuma manages to get around situation by making onigiri for him and Tenma with the rice. As it turns out, Harima spots them having lunch together, and feels so heartbroken the next day that he refuses to go to school and spends his day watching TV. Watching an episode of "The Three Who Were Slashed", he imagines that what he saw was nothing but a misunderstanding, and concludes that Tenma and Karasuma may be siblings after watching a Star Wars spoof. Trying to see things in an optimistic light, he is unexpectedly (or not) visited by his fighting rival, Noboru Tennouji, who had challenged him the day before. Unable to react due to his broken feelings, Harima takes the beating of his life.
