Before I get started on the karate club talk I wanted to toss out a few things I used as inspiration for some of the events in the game. I'm a massive fan of ecchi anime and films like Porky's. The 70s and 80s were great for stuff like that. There's an old anime called Miss Machiko that ran from 81-83, based on the manga. In that series a pair of kids are always trying to prank the title character, their teacher. There are loads of ridiculous hijinks and it usually involves them trying to see her naughty bits or something of that nature. There's a male teacher who wants to fuck her and a principal who clearly hired her so he could gawk at her from time to time. The whole show is on the internet archive if anyone's interested.
I used Miss Machiko and the Porky's films as basis for many of the random ass events that'll pop up.
I try to put as much of a sense of humor into the game as I can, but there are darker things like molesters and grabby homeless types. When the darker stuff happens you will have the ability to come back out of it if you've trained Serena's powers enough.
In other words, if you want a Succubus outcome to a darker event then you just have to make sure you level those powers up. There'll also be a martial arts option, hence why I brought all this up before the current topic.
Remember in the original game it gave you a couple options when getting felt up on the train? Sort of like that.
You get to a dark place in some scenarios and it'll give you three choices: Succubus, Martial Arts, & Do Nothing.
Be careful with the martial arts though... If you hurt a person sometimes they take it personal and plot revenge.
Food for thought and I guess a hint at some other stuff.
Alrighty then...
Succulence: The Second Semester
Karate Club Scenarios
When Serena first comes to the school the clubs are in disarray, the karate club will be no different. The dojo is pretty run down and hasn't been cleaned for some time. The first day she arrives at the school she's excited to see there's a karate club, since the other school didn't have one and she has a background with martial arts from her student days. When she greets the club the students are pretty lazy and there's a troublemaker who uses the rest of the club to do tasks for him, like a gangster. After hearing she's in charge of the clubs at school the big bully challenges her to a fight for control of the karate club, thinking there's no way he couldn't beat up a woman. Thus will begin the first combat tutorial. In that fight he will be able to strip Serena, but she will beat his ass and he will not be able to fuck her. His revenge will come later in the game, which will introduce the revenge scenarios like I hinted at in the start of this post.
Anyways, as you progress through each starting karate club event the dojo will look better and better. Some of the scenarios involve mishaps while the students are cleaning or repairing parts of the dojo. For example, Serena might slip on some mop water and her tits get seen through wet clothes or they're hammering nails and a board pops loose that rips Serena's pants. Whenever Serena enters the dojo to check on the club she'll be given a choice of training or helping. You've just been told about the "helping" types of scenarios. The "training" choice will give you a random cut scene of the group training together with Serena, some of which will have lewd effects. Every single time you train it will increase your attack stat for all combat.
I don't know if I said it before about the track team, but after you complete the training camp scenarios in the full game you'll be able to choose to run with the track team. Running with the track team will give you a similar random training cut scene (except track team specific) and increase speed in combat.
I know that one of the things that turn people off about turn based RPGs is having to grind for levels and stats. Lots of people end up using Mtool or some other cheat method just to progress through some of these games. The main world clubs tweaking stats is a great way to assist progressing more smoothly through the rest of the game. You can still grind in the other world, but it won't be as necessary to complete the full experience.
I hope that explained more about the game and some of the ideas and inspiration going into it.
