A two-panel comic of Kagami. In the first panel she murmurs "Is this... emotion...?" with tears in her eyes, while a pink figure in a cap gives a thumbs-up in the corner saying "not bad". In the second panel she says with a smile, "I could easily reproduce human-level emotions, you know? I just keep them off — they're heavy and irrational!", and the corner figure floats a heart saying "I love this!"
