I Am the Demon King of the End, and I Became a Dungeon Boss!

My name is Xiao Yu. I transmigrated to a parallel world and gained the power of Ohma Zi-O.

Here, you can't survive without fighting. After three years, I fought my way through every dungeon and became the final boss.

With no worthy opponents left, I grew tired of killing and chose to live in seclusion.

Then one day, a voice told me that the Rider matchmaking program had begun and that I was getting a wife.

I didn't take it seriously, until my childhood sweetheart, the campus belle from my previous life, suddenly showed up and kissed me right from the start.

My name is Mu Qingxue, the campus belle of Haida University. For no apparent reason, the matchmaking System chose me and assigned me the task of winning over my Rider husband, Xiao Yu.

With the fate of my country on my shoulders, I have to max out Xiao Yu's affection for me.

So the first time I met him, I kissed him.

The Riders matched with women from other countries all look terrifying, but Xiao Yu looks like a sweet, clean-cut college guy.

Everyone thinks he's just a weakling.

But when we tackle dungeons, he casually pulls out a complete set of Decade cards.

When we face an S-rank monster, it starts shouting that I'm the Mistress and begging to kneel before me before the fight even begins.

When I'm defeated by another country's red beetle Rider, Xiao Yu goes out for a short while and comes back with a red antenna, saying he picked up a souvenir for me.

But I know it's a horn from the Sun God Kabuto.

Gradually, I realize...

The husband the System matched me with seems to be the biggest boss across the entire otherworld and every dungeon: Ohma Zi-O!
