To Support My Little Sisters, I Built a Clubhouse for the Myriad Worlds

What if, just what if,

Sagiri Izumi and Kaede Azusagawa,

Sora Kasugano and Kirino Kosaka,

and Natsuki Momohara and Kobato Hasegawa

were all your biological sisters, despite having different parents? How would you handle that?

Ayanokoji has already pulled it off, and after years of hard work, he's raised six little sisters.

And what about his older cousin Kobayashi, and a few dragons?

I can't afford to raise them all. I really can't!

Left with no choice, the protagonist accepts the System: Myriad Heavens Clubhouse!

A clubhouse System serving the Myriad Worlds!

Liang Bing: Boss, can I book you for some personal service?

Ayanokoji slams the table: Service? What kind of service? This is a respectable club!

Yaya Tushan blinks: Then how do you explain all these cute maid waitresses, big brother?

Hideyoshi Toyotomi beams: Do you mean me, little Yaya? I'm happy you think I'm cute, but I'm a boy!

Aoi Hyodo fidgets: I... I'm a boy too...

Hime Arikawa: Me too!

Ainz Ooal Gown: Doesn't that make it even better?

Yato: Bro, you smell so good...
