Shizuku Kuroe

Shizuku has deep violet hair and purple eyes. She wears a dark purple maid uniform with a black headdress and tights.

Shizuku Kuroe is a character featured in the sequel of Saint ♡ Slippery's Academy for Girls video game series. Marin Kitagawa is a big fan of her, so much so that she wanted to cosplay as her, which also was her cosplay debut. She had tally marks up to 17 on her thighs, which is indicating how many sexual encounters the character had, so it is possible as the more sex you had in the game the more tally marks would be added to the character's thighs in the game.
