Infinite Worlds: Building the Strongest Harem

Ryuji, through a fateful accident, arrived at an Earth similar to a parallel world. Just as he was adapting to circumstances, he was suddenly selected by the Reincarnation Space, becoming the first Reincarnator.

Looking at the countless reincarnation worlds, he decided to build the strongest and largest crystal palace that belongs solely to himself.

(Author Note: The author is a pure love warrior, so readers with any concerns can consume this content with peace of mind. All characters in the story are virgins and exclusively devoted, all settings are based on this book, and please don't impose too much from the original works.

This story will not contain soul transmigration, masks, clones, NTR, dead heroines, desecrated heroines, or other problematic tropes. Non-purely female characters (femboys, futanari, hermaphrodites, etc.), non-virgins, and lkd will not enter the harem. Content that makes protective readers uncomfortable (pseudo-yuri refers to not being yuri, yuri is used as a cover) will be avoided.

Shared heroine = gifted heroine = cuckolding. If any shared heroine situations appear in the story, please classify them among the nameless beauties collected by the male protagonist. After all, my energy is limited and I cannot be comprehensive in every aspect. The male protagonist will basically have complete control over every world he visits, and the beauties within naturally all belong to the male protagonist.)
