After his own mother killed him, sky woke up in an unknown place. They are all dark... Even his hands were unseen. Wait...Does he have hands? ...Of course not... Because he was killed when he had lost everything he had. [Hello, host! I am the steal white lotus halo system. I'll be your system and assist you in your mission in every world]. A voice that sounds like a little girl with a cheerful tone. "huh?! W-wait!!!" [Bu bye host! See ya later!] Well... You can see what our sky and system do in every world... Find a husband?... Nope.. Of course a harem.
