Anime Crossover: From the Start, I Activated the Overlord System in the Cautious Hero's World

Yoshino Arima was unexpectedly summoned to the other world of Cautious Hero. At the brink of life and death, he activated the Bone King System...

But with too little time, he only managed to activate 50% of the Bone King System...

Well... wouldn't that be even better? Yoshino Arima at least discovered that his XX function was still working!

From then on, the beautiful and holy goddesses of the divine realm, the kind and adorable girls of the other world, and the lovesick, sensitive guardians of the Great Tomb of Nazarick all gathered around Yoshino Arima.

What? Humans and goddesses can't fall in love? Then I'll become an almighty Demon God and marry them openly!

What? Guardians steeped in the aura of the undead can't enter the divine realm? Then I'll become its ruler and change this ridiculous rule!

The story begins in Rista's previous life, before she became a goddess. An original protagonist changes the main course of the world! No tragedy for the protagonist, no giving the girls away, pure wish fulfillment. Later on, more transmigration to other worlds and everyday-life adventures can be added...
