Luocha from Honkai Star Rail. Luocha carries a coffin with him for 24/7, and what's inside is a person, or rather a jiangshi. A jiangshi is also known as a Chinese hopping vampire/zombie, and their body are cold and stiff since they're a corpse(reanimated). The jiangshi is actually Luocha's dearest friend who died and came back as this creature.
