When Takeshi was five, his mother collapsed onto the floor of the kitchen. Takeshi had been in the other room, watching his then favorite anime, when he heard the sound of dishes shattering. His father had been watching him and quickly ran into the kitchen. Takeshi couldn't really remember what happened after that, only that they ended up at the hospital. What followed after that was his mother soothingly rubbing his cheek as he and his father left the hospital, leaving his mother alone in her room. Takeshi didn't know what, exactly, had made his mother collapse but he was told that it wasn't serious and that his mother would be home soon. That all changed when his mother began vomiting blood. It happened during a visit, his father out grabbing lunch for both him and Takeshi. Takeshi had been telling his mom about what happened during school that day when she started coughing.
"Mom, are you sure you don't water?" Takeshi asked, his brows furrowed as he watched his mother hunch in on herself.
His mother chuckled as she removed her hand from her mouth. "I told you I'm fine, little warrior. Now, what was that about Sawada-kun?"
Just as Takeshi opened his mouth, his mother's hands flew to her mouth and she let out wet sounding coughs. Takeshi jumped to his feet and ran out of the room when he saw red trickle down onto the hospital sheets from between her hands.
"Help!" he screamed, frantically running down the hall, "My mom! She's coughing up blood, please help!"
A nurse tried to comfort him as two others ran to his mother's room, telling him that everything was going to be okay. However, Takeshi wasn't listening, his blood roaring in his ears.
Yamamoto Rui passed away one month after that visit. His father was devastated but didn't spend much time mourning, immediately comforting Takeshi and trying to figure out how he was going to raise his son. Takeshi, on the other hand, felt like he was frozen. He had always been closer to his mother, always stuck close to her. Now that she wasn't here, he didn't know what to do.
