Starting a Life Together with a White Cat Girl in Another World

Arca is an S-rank adventurer and otherworlder who happens to be a shy, reclusive shut-in with a weakness for young girls. After traveling the world in search of his ideal companion only to have his dreams dashed, he retreats into isolation. His quiet life changes when he encounters Noah, a beautiful enslaved girl with pure white cat ears. Captivated by her earnest nature and hardworking spirit, Arca envisions the perfect life together. However, it is Noah who ends up pulling the reluctant shut-in back out into the world, reigniting his adventurer career and dragging them both into a relentless series of incidents. What begins as a simple two-person household quickly spirals into something far grander. As Arca—secretly a wicked witch capable of charming beautiful girls—and Noah journey together, their bond deepens, and their family steadily expands into a sprawling household of over a hundred members. From subjugating demon lords and exploring underground kingdoms to confronting false gods, vampires, and warring empires, their adventures transcend time and space itself. Balancing epic, world-shaking crises with lighthearted daily life, this ever-expanding tale follows an overwhelmingly powerful protagonist and her growing harem as they charm the gods and bring peace to the world.
