Good day to y'all. I really need some help regarding the title of a novel that is bugging my mind for quite a while but can't seem to remember the title. Here are the key words I remember: Asgard, Laputa, El Dorado. The MC was like defeated before in his land named Asgard where he had a Butler named Alfred. On his second chance in life where he returned back in time, he chose a flying piece of land named Laputa. He also know a girl who owned El Dorado. He was first attacked by a Japanese kid with an army if ants and centipedes. And he hates a guy named Rothschild. I hope I am right with what I remember. But do please help. I would really appreciate the gesture.
