How about I let you weep.jk, fantasize whatever you want bro.
I choose to dream of Lum
As if Lum wouldn't shock Ataru to death by the time he reaches 30. No matter their differences Shinobu and Ataru would be able to smooth everything out and understand each other as two humans. Something a psycho space alien would never get.
If Lum is a princess then her father is the king right? So if Ataru and Lum marry each other wouldn't that make Ataru king consort of the planet Oniboshi? I suppose that the Earth would just be given as a gift to the Oniboshi royalty in exchange of the marriage.In conclusion, if Lum and Ataru marry each other the Earth is screwed.
