For me It's

1. Kenkou Cross

2.Ganmarei

3.SNOWBALL ( Who does some of My favorite Last Origin Wives).

4.nishii(Nitroplus) Cause of Nanatsu no Bitoku

5.Zun (Creator of Touhou)

6.Houtengeki

7. Katou Shinobu

8.Sakimichan

9. Kim Hyung Tae

And If Kenkou Cross or Ganmarei made a servant I would do all that I can to get them 5/5 as I am a huge fan of Monster Girls Encyclopedia. And Monster Wrestling Interspecies Combat Girls Manga. And just monster girls in general
