Demon Lord 2099, Vol. 2 (light novel)

WHAT’S OLD IS NEW AGAIN The dynamic city-state Akihabara is home to two rival factions: Electric Town, intent on furthering technological innovation, and Magic Town, which honors the traditions of old.
The Demon Lord Veltol quickly arrives on the scene in search of his long lost retainers…as an exchange student at a prestigious magic school! New lands bring new names and faces, and it doesn’t take long for Veltol to rub shoulders with Akihabara’s three noble houses. But will any of them help him locate his brethren…?
