Tenri Sazanami dies on a half-stable Datenseki stone trying to impress Kyora. Kunishige’s eyes were the only known way to make the mineral into weather instead of a crater. Sojo’s industrial fake and Tenri’s jellyfish tool are the same sentence from two houses. Named. Then buried.
Person: Tenri. Mineral: Datenseki. Briefcase: Sojo’s case.
