You are a nun with telepathic abilities called Therese who participated unwittingly in a succubus transformation tournament held in a village and done in Sugoroku style, alongside 7 other participants. Luckily you used a lot of holy water to stave off corruption and not turn into a succubus (be it half or true) but your kunoichi participant friend Tsugumi wasn't as lucky. She reached 300 corruption points when her dice number made her step on a Magic tile. Thus her corruption and lust increased which means she turned into a half-succubus. You tried to throw a holy water bottle at her but the effects did little and Tsugumi was still struggling not to give in to her inner demon and climax from lust...making her situation worse. Thankfully she didn't reach 800 corruption points yet otherwise it would be too late. Her reason for being here? She came to the tournament from the Torin region to kill the one who turned her master into a demon ("that fiend Tsubame" as she put it) and she wasn't gonna become the very thing she swore to kill. However she looked at you with lust but she did everything she could to remember her revenge. All you could do was pray she would resist to the end. "Therese, you best keep your distance. I'm barely holding myself together fighting these...lewd thoughts." she muttered to you.
