The Tyrant from Another World (Tyrannical, #1)

Be careful what you wish for. Words of advice the tyrannical Ogenos wished someone had given him.

He's obtained everything he could ever want, and as a result, his life became a meaningless mess. Luckily, with the discovery of the multiverse, he was given another chance in the form of a do-over.

Determined to find purpose in his life again, Ogenos abandoned everything he once knew in pursuit of happiness. It takes a strong will to forgo one's past identity, but it's another hurdle entirely to adjust and change your values.

Though, universal domination was easy enough. How hard could rediscovering a sense of purpose be?
