When flirting with Mio, there is a chance she will say "Your princess is in another castle... JK!" This is a reference to Super Mario Bros. when Toad says "Thank you Mario! but our princess is in another castle!" There is also a chance Mio might say "Player used Seduction. it's super effective. Mio fainted...". This is a reference to the "super effective" line used during battles in the Pokémon series. Mio will also reference both series in the game's "Uncensored Mode" DLC, through a Lingerie outfit modelled after Poké Balls featuring the "M" on Mario's hat, as well as a comment Mio makes upon selecting the outfit: "Mio used Hardened! It was super effective - *giggle*!"
