Yu-Gi-Oh, this sister card is worth a lick

This is a world where cards determine everything, and it is also a world where elves and humans coexist.
Good news, Zhao You has a system.
Bad news, what Zhao You got was a dog-licking system.
The news was neither good nor bad, as his card book was also brought along and became part of the system.
Zhao You: Are you trying to make me laugh by giving me a love system in the card world?
System: Who said it was funny? If you want the card, why don’t you lick it (cross it out) and chase it?
You see, it's easy to deal with this Hades. As the saying goes, to conquer a goddess, you must first conquer her stomach. The task is: conquer the other party with food, and the reward is: the favorability of the Hades.
Kurikara Tendou: I don't think it's possible and I withdrew a mission. New mission: Defeat the underworld god in front of you. Reward: Marry her.
The whole world has changed dramatically since then.
The Evil Twins, the Insect Demon, the Pearl Tears, the Fragrance, the Dragon Maid, the Kusha Angry Tribe, Leo Ku, the Golden Kingdom, take them all down!
Hmm? You ask if something weird got in there.
Zhao You: How can you define their gender?
