Episode 2 titled "My Big Sister's Perfect Food!" is the second episode of the Null & Peta anime series.
Summary[]
The episode opens with Null being gently woken up by Human Peta, which is quickly revealed to be an imagined scene by Null. Instead she is woken up by a self-made alarm clock, and sent through a contraption getting her ready for school. She lands in front of the living room table, opposite to the Peta robot.
The table is decked with tasty food, but when Null delightfully tries to eat, it turns out to be a hologram. Instead of the unhealthy rich meal, the real food prepared by Peta is her signature dish called "Dark fried rice", a dreadful fried rice dish of purple-ish color, with a bamboo shoot added on top. According to Peta it is a "perfect food" (as in the title, here probably: "nutritious") with "great cost performance".
Null however is frightened by the dish's appearance, and soon runs away. She is then seen in a quiet place, trying to eat a snack bar instead. Peta follows her around, however, insisting on Null eating her rice. A chase sequence follows, with Peta firing bamboo shoots at Null.
Null soon finds shelter in an old factory-like building, only to come out armed with a mecha, which reverses the chase. Null manages to shoot up the fried rice plate, but her durable sister robot still pursues. This prompts Null to abandon and destroy the mecha, presumably eliminating Peta as well. When this also fails, and Peta steps out of the flames with a freshly fried bowl of rice, Null is left no option but to give into Peta's request. The last shot metaphorically depicts Null's spirit "departing to the afterlife" in expectation of the horrible dish.
