Luffy:
Your costumes match in every way. He's Frankistien's monster and you are his bride.

Zoro: You guys didn't match. Zoro went as a Vampire and you went as a witch.

Crocodile: Neither of you dressed up. You both stayed home and relaxed.

Ace: Ace wanted you two go as a dragon which you did after a lot of persuasion.

Doflimango: Doffy went as a human bird hybrid while you went as human deer hybrid.

Sanji: You got sick so you both cuddled the whole time.

Mihawk: He is already terrifying. So you just made a outfit similar to his.

Katakuri: This was the only time of the year where you both could express your selves. He took off his scarf and you showed your blood red eyes.
