Top 5 Pedophilic Shippings
Not quite sure what this question's asking for. Like, pairings with major age differences? Adult/Minor? May-December romances? There might not be a whole lot of these either. I'll do my best.
1. Jacob/Renesmee (Twilight Saga) Yeah yeah, shut up. Imprinting... fascinates me. And it completely hits my kink for May-December romances where one party is almost sort of maybe a parental figure in some ways but not really.
2. Aram/Airi (MeruPuri) Again, it's the caretaker who's not actually a parent substitute thing. I dunno it just... does it for me.
3. Sebastian/Shonda (Jumping the Broom) Not technically pedo since both are over eighteen but there are cougar jokes made so I'm counting it.
4. Shohei/Urd (Ah! My Goddess) Urd was stuck in child form when she met him, then when she got cured promised him he could come back and see her when he was older. It counts.
5. Haku/Chihiro (Spirited Away) Who knows how old river spirit and ten year old girl? I guess it counts.
