Ichazura ~Itazura Gokuaku Fandisc~

Ichazura. Ichazura is a fandisk to the game known as Itazura Gokuaku.
Itazura is the 'main' game where the main character basically gets arrested and goes to prison for being accused as a chikan/train molester. He gets out and decides to take revenge by being one. Ichazura is the 'fan disk' and covers what happens after the 'good' ending where he gives up being a Chikan and the girls have pretty much 'fallen' for him. As for how they play it's practically the same except obviously the first one deals more with molesting and then 'breaking' the girls as opposed to all the scenes in Ichazura being consensual.
