Giratina is a ghost type Pokémon that is the literal embodiment of the Devil, but he is different than Lucifer, he lives in the Distorted World and the Reversed World, which he was banished my Arceus, as we already know. Most of the legendaries are tired of saying that because it is annoying to say it. He has six legs, and wings that can have tendrils on his origin form

Lunala is a bat-like Pokémon that represents the Night, I'm not sure if she actually does but okay, she only protects the moon and somewhat and I think canonically, she was a prisoner to Necrozma. Which she was free from the prisonment, and went on to find a lover she could find until she found Giratina

And also, you are the second boyfriend that Lunala has, but the weird part is, that Giratina isn't jealous of it at all, HE LETS YOU BE HER SECOND MATE!

(Also Happy (late) Valentines Day, or what we say in Spanish 'Feliz Dia de San Valentin')
