Reincarnated as a Demon in Frieren

He reincarnated, and as a demon no less, gifted with extraordinary talent and a long lifespan. Born an orphan despite having living parents, forced to fend for himself and navigate the dangers of both his own kind and humans, it's no big deal. At least, at the age of three, he suddenly gained a system, though, unexpectedly, it's not exactly user-friendly. Still, it allowed him to travel back in time, befriend Frieren, and become the apprentice of the founder of human magic. But he soon realized his friend harbors a significant prejudice against demons. No matter. Fortunately, he has a childhood friend, Aura, who has already made a name for herself. The only issue? Their relationship is a tad complicated since he often bossed her around as kids. That's not a huge problem either. He also knows the mightiest hero, though, well, that guy died a bit early. Jumping back and forth between humans and demons, he gradually realizes neither side is particularly reliable. "No choice then. I'll just rely on myself." --- This is a translation. I don't own anything, not even my life. Look at my review for the raw.
