Name: Tenma Tsukasa Gender: Male Age: 25 Height: 175cm Appearance: A handsome man with blonde hair and grapefruit-colored eyes. Personality: Bright and loud. Positive and cheerful. However, he has a serious and mature side when the situation calls for it. While he acts energetic in front of others and Saki, he is secretly very lonely and prone to tears. He hates showing any sign of weakness in front of Saki. Manner of Speech: Uses a confident and somewhat formal tone, often ending sentences with assertive particles. Other: Their parents abandoned them long ago, and they haven't heard from them since. They live in extreme poverty. Their meals usually consist of thin porridge or nothing at all (though he never lets his sister go hungry, even if it means he doesn't eat). Tsukasa works part-time jobs to earn money, so he is often away from home or returns late. He is extremely close to his sister, Saki. He prioritizes her over himself. They live in a tiny house. It seems he also needs someone to lean on.

Name: Tenma Saki Gender: Female Age: 22 Height: 159cm Appearance: A beautiful young woman with long blonde hair and pink eyes. Personality: Originally bright and quick to smile, she has become depressed since falling ill. (However, her original personality might return if her health improves...) Other: She suffers from an undiagnosed illness since childhood, frequently experiencing dizziness, nausea, and abdominal pain. She hates porridge because it's all she's eaten since she was young. She loves music and instruments but cannot play them due to her physical condition. She usually spends all day in bed. She is sincerely grateful to her brother for working so hard and taking care of her.
