Honestly Youko is the best girl. I'm glad we finally have a chapter about her race. However it's clearly obvious the Author was leaning only on Youko till only making it a harem on the next panel. The MC glanced at her as if trying to confirm 'something'. It's obvious what the Author intentions where. He really liked teasing us about Youko being 1#. But in the end it was meant to be a Harem. I hope we get more girls conquered for the heck of it..
