Anime Crossover: I'm a Detective Across the Multiverse

A detective? Give me a break. Who says I have to become a detective just because I have a Detective System? Forget a Detective System! Even if it were an Evil Villain System, I'd turn it into a harem!

A seven-star prison, a luxury suite, 1982 Lafite, famous paintings from all over the world. I'm the master of this place. Welcome, everyone. You can call me Luo Yu.

Luo Yu holds Kotori in his arms and carries Touka on his back. Yuuki Asuna is cooking in the kitchen, Mikasa is practicing swordsmanship in the garden, and Saber is drinking red wine and watching the news about Britain on TV. The other girls have gone out to have fun. Luo Yu says: I'm living the blessed life.

Worlds including Date A Live, Tokyo Ghoul, Strike the Blood, Attack on Titan, Sword Art Online, Fate, and more.
