Multiverse Sign-In: Starting as the Herrscher of Reason

When disasters invade a collapsing anime multiverse, one transmigrator awakens the ultimate cheat: the Myriad Worlds Sign-In System. Each world conquered grants him godlike powers—from Genshin's Heavenly Principles to Demon Slayer's perfect immortality. But power isn't his only reward. As he establishes order across crumbling realities, beauties from every dimension fall for the man who saved their worlds. The Herrscher who came for survival stays for conquest—of both worlds and hearts.
