My Harem Is a System

Can I tell you that the System is the real heroine? There's a big-sister-type Mythical System, a daughter-type Enhancement System, a queen-type Summoning System, a yandere-type Main God System, and a whole bunch of weirdos: cross-dressing maids, silver-haired young ladies, lolita saints...

P.S. Hahahahaha! What haughty young lady? What expressionless saint? What adorably clueless cross-dressing maid? They're all fake! Hahahahaha! Let go! I'm not crazy, protect the Emperor! Protect the Emperor! There are always scheming villains trying to frame me!
