The first was Diabolik Lovers. I loved Subaru in the anime and wanted to know what his route was like, lol. But what really interested me was Black Wolves Saga. Those cats are truly traumatic, but I loved the art style and all the characters except the cats, lol. My second otome game, but for me it's the first, since unlike DL, I actually played both games and all the routes of this one (ᵔ◡ᵔ)
