Plus-Sized Elf

Kuroeda has created a suspicious potion using black magic and plans to have Erufuda drink it as an experiment. He brings the bottle containing the potion to Naoe's room where Erufuda lives, but Naoe, who has returned home earlier, accidentally drinks it. Kuroeda intended it to be a weight loss pill, but after drinking it, Naoe turns into a young child! Kuroeda tries to retrieve the potion and somehow return Naoe to normal without anyone realizing that he is the culprit, but Oga, who had promised to teach Naoe how to cook, arrives.
