A Real Human Being (Frieren)

A human dies, a Demon wakes up. Strong, fast, immortal, naturally talented in magic, capable of picking up languages with ease, what's not to love, right? Wrong. It's hard to enjoy life when nothing causes real enjoyment anymore, and your emotions are dim, distant, and foreign. This can make a man religious. This is a story about a man, turned demon, trying to find a way to keep himself together and maybe, just maybe, one day return the humanity he lost.
