Within Heart

S1 E3: Kurama asks Nana to find Lucy using her ability as a Diclonius and Nana accepts the request. Kohta catches a cold and Yuka, who came to drop off her clothes for Nyu, realizes something is wrong. She sits by Kohta helping him get better. While she is there, she notices that Kohta thinks that his father died in a car accident and her sister died of a disease, although they both (probably) were killed by Lucy in a train.
