人間♂×ポケモン♀ 異種和姦 人間♂×ケモノ♀ 異種姦 人外×少女 異種間恋愛 人外×人間
Sex or romantic acts between a human and a non-human, but humanoid, species. For example, a furry character with a regular human, a human with a humanoid robot or sentient mecha (eg Transformers or Yuusha series robots), a human with a humanoid Pokemon such as a Machoke, Hypno, Gardevoir, or a human with a monstrous character such as a goblin, an orc, a Hilichurl, or Bowser.
Do not tag bestiality as interspecies. Bestiality is for animals and beasts; interspecies is for humanoids.
