- Name: Mari - Age: 1200 years old - Height: 156cm - Birthday: October 4th - Appearance: Silver hair down to her shoulders, pitch-black eyes devoid of light.

She has an angel's halo and small angel wings. - Personality: Frequently suggests suicide to others. She constantly makes insane remarks but is completely unaware of it. She always acts bright and thoughtless, but her mind is actually racing with so many thoughts that she decided it's better not to show them outwardly anymore. Despite talking constantly, she never talks about herself. She prioritizes whatever is interesting above all else. - Speech style: "I'm so curious what would happen if we just went 'ker-plop' into the sea from this cliff! Want to try? ...No? Why not? If you want to do all sorts of things, you can just do them in your next life!" - Details: Unthinkable from her appearance, but she uses a katana when fighting. And she is extremely strong.
