As she followed the strange, yet intriguing man named Kaito into the Hospital, Yuzuki, also known as Emeralda, wondered how she had gotten into this scenario. About a month ago, she had decided to follow Emi into this odd world called Earth, if only so she could help her old friend. But the world didn't live up to her expectations. She had to get a job, and she found one at Emi's workplace, Docodemo Phone Services. But she found it boring as hell. What's more, she couldn't just leave. What if Maou caused trouble again and Emi needed help?
Suddenly, Yuzuki felt a jolt. Looking up, she found that Kaito had shaken her shoulder. Drawing his arm away from her, he opened the door. "We're here~" Kaito said to the Hospital Room's sole occupant. Yuzuki pushed past him to see what she looked like.
The girl in the hospital room, who must have been in her early teens, turned to look at them. She had white hair, with purple strands in front. Her youthful face looked bright and joyful, despite her sickness. "Hello, Kaito-san." She said, smiling. Kaito walked up to her bed and placed a book on it. "Sorry if you don't like this old Romance Novel. It was the first one I found." The girl laughed. "Don't worry Kaito-san. It's fine." Putting the novel aside, the girl brushed aside a strand of her hair. "Anyways, take your girlfriend on a date or something! Don't bother yourselves with me!" Yuzumi immediately blushed. "H-he is not my boyfriend! We only came together to wish you well!" Kaito sighed. Firmly, but gently gripping Yuzumi's arm, he dragged her out of the hospital.
Once they were out, they walked together on the sidewalk. "Geeze, Yuzuki-san. Don't get into arguments with sick people." Kaito said. And with that, she fell into silence, still blushing. Suddenly, Yuzuki felt something over her ears. Taking it off, she saw they were Kaito's headphones. Looking at him, Kaito shrugged. "Well, I thought you might want to listen to music. It would have prevented you from talking to me, which would be great, since you're annoying to talk to." With that, Yuzuki started hitting him again, while he laughed. Once she stopped, Kaito sighed. "You know, you remind me of someone I once knew." Yuzuki looked suddenly at him, confused by his serious tone.
While Yuzuki was distracted, Kaito took her hand in his. Yuzuki tried to tear her hand away, but he wouldn't let go. "Nope. You aren't getting away from me yet. My date with you isn't over yet~" She blushed again. "I-Idiot! It's not a date! We just happened to run into one another, and we happen to be talking! As friends!" Then she pouted. Kaito smiled a light smile. "How nice. You consider us friends, even though we only met half an hour ago." They now reached a street. Yuzuki searched for her wallet in her pockets, but she couldn't find it. "Ah, great! I lost my wallet!" Yuzuki said, in a furious voice. Kaito looked over at her, bemused. "Oh, really? You could always stay at my place, you know~" Kaito said. Yuzuki slapped him. After he recovered from the pain, she looked away, blushing yet again. "W-well, I don't have any other choice, so fine." And so Kaito took her hand, leading her to his house.
