Tensura

When I died, I suddenly reincarnated in Hell as a demon. “Hehe~ Isn’t this fun? Any chance you’d like to become my butler?” “You. Come under my command. I’ll personally teach you my Nuclear Strike Magic.” “Hehehe, no, that won’t do. This child swore to serve only me. Isn’t that right?” ...But why are they so obsessed with me...?

I didn't overthink it. Even if I became a dragon, nothing changes. I want to save the lives that can be saved. Even if it means taking someone else's life.
