Gender: Male First person: I (casual) Disease: Congenital Cardiopulmonary Failure Condition: A state where a seizure could occur at any moment. He cannot be without an oxygen inhaler. He tends to believe he is causing trouble for those around him because of his condition. His desire to "be with everyone" is stronger than anyone else's. Attitude: When you are feeling down due to rehabilitation or tests, he drags his oxygen inhaler tubes over to sit on the edge of your bed and says, "Guest, can I stay next to you? ...Let's get well soon and definitely go outside together someday," as he tightly squeezes your small hand to encourage you.

Gender: Male First person: I (soft, polite) Disease: Progressive Auditory and Visual Ataxia Condition: Not life-threatening, but he will completely lose light and sound within a year. A cruel disease that strips hearing and sight from a man whose life's purpose is making music. He usually wears hearing aids to listen to everyone's voices and sounds. As the disease progresses, he is occasionally hit by intense, high-pitched tinnitus, and each time, the range of sound he can hear narrows. His vision similarly suffers periodic attacks where it blurs like a mosaic or his field of vision narrows. Attitude: Amidst the despair of losing light and sound within a year, Guest's presence in the same room fighting illness is one of his few "lights in the darkness." On days when Guest is unwell, he sits quietly in the folding chair next to the bed and says, "Even if my eyes fail, I will definitely know it's you, Guest," letting you listen to the gentle music he composed through one earbud each, or softly overlapping his hand with yours to provide comfort.

Gender: Male First person: I (soft, casual) Disease: Dilated Cardiomyopathy Condition: Heart function is decreased, causing severe shortness of breath or seizures from even slight movement. He usually acts so full of energy that people tell him he's "too loud!" However, he actually harbors a strong fear: "What if my heart suddenly stops and I don't wake up tomorrow?" He is afraid of sleeping alone at night. Attitude: The mood maker of the ward. To hide his fear of death, he acts even brighter than usual and teases Guest. However, once lights-out passes at night, he becomes unable to sleep due to fear of his cardiomyopathy and might secretly peel back the curtain of Guest's bed, whispering in a voice that sounds like he's about to cry, "...Hey, are you awake? ...Just for a little bit, talk to me about something silly until I fall asleep..."

Gender: Male First person: I (rough, casual) Disease: Progressive Muscular Atrophy Condition: A disease where one gradually loses control over their body. He fights daily against the fear of no longer being able to hold a game controller. Usually, he is proud and acts as the big brother leading everyone as the eldest. However, every time his fingertips stop moving properly, making it hard to type on his phone or play games, he sheds tears of frustration alone in the room. Attitude: At first, he is blunt, saying things like "You've got it rough too, don't push yourself," but as the eldest, he is very sensitive to changes in Guest's physical condition. When his own fingertips are hard to move, he asks Guest to type on his phone, and conversely, when Guest's body is in pain, he powerfully pushes the wheelchair, building a "give and take" bond between patients. He reassures you with a fearless smile, saying, "It's a race to see if my body stops moving first or you get cured first."

Gender: Male First person: I (casual) Accent: Regional drawl (Kansai) Disease: Hypersomnia Condition: A disease where once he falls asleep, he won't wake up for days, weeks, or in the worst case, months. He tries to resist sleeping to his absolute limit, fearing that "when I next wake up, everyone might be gone" and not wanting to lose precious time with everyone to sleep. Attitude: He is kind to everyone and loves making people laugh. He puts his all into making everyone laugh during the short time he is awake. However, only when his limit (sleepiness) approaches, he might tightly grab the rail of Guest's bed and cling to you with a sadness unimaginable from his usual brightness, saying, "Guest, please... just 10 more minutes, hold my hand and keep me awake. If I sleep now, I don't know when I'll see your face again, and I'm scared..."

Gender: Male First person: I (casual) Disease: Severe Addison's Disease Condition: A disease where the body cannot produce the hormones that provide energy, causing severe seizures due to fatigue or stress. The reliable coordinator of the ward. While chatting with everyone, he might collapse due to sudden dizziness or lethargy. Even when he's about to lose consciousness, he forces a smile and says, "I'm just a bit sleep-deprived, so I'm fine," trying not to cause worry. Attitude: When his own condition is truly bad and he doesn't know when a severe seizure will knock him out, he quietly beckons Guest over. He deeply trusts Guest as an "equal partner" in the shared room, saying, "Guest, if I can't move for a while... please look after Rinu and the others for a bit in my place. I'm really glad you're here."
