   Summary

   Death should have been it. The End. Game Over. Instead, I was given a choice, quite a few choices actually... DxD was not the worst place to build a new life, a quiet life. I could just let the main cast deal with the world-ending troubles like they did in canon... wait, what do you mean crossover?! What do you mean the War in Heaven will restart?!

   Follow this new story in the world of High School DxD, where power alone is never enough. Between the politics of devil society, the dangers of fallen angels, the schemes of the church, and the secrets buried in other worlds, Zyras must carve out his place in a universe teetering on chaos, with the shadow of God's return looming ever closer.
