Summary
At the Hasegawa Residence, Kobato prepares a bag of potato chips with hot condiments that she plans on giving to Maria later. Kodaka walks in and tells her to go to bed. The next day, Kobato runs into Yukimura on her way to the Neighbor's Clubroom. Yukimura says that he was on his way to the clubroom to deliver Maria her lunch. Kobato, not wanting Yukimura to go with her, decides to deliver the lunch for him. At the clubroom, Maria refuses the gift saying that Kate told her not to accept gifts from vampires. The two begin to fight. Sena takes the offering, saying that if they don't want it, she'll have it. Sena downs the bag and falls to the ground. Kodaka asks what Kobato did to her while Yozora delivers "the final blow" to her head with a half-eaten popsicle.
