Thanks for the walkthrough
Hint: After visiting the old school building the first time for the chemistry club, and turn around,
cause of the smell, visit the toilet at the ground floor of the main building.
There are aditional scenes with the photography club member and later her classmates.
And for the fighting:
- for the rats i put the start points into power (5 rats minimum... and i got with some heal up to 11 <- the resulting statpoints were helping a lot)
- for the normal fights, i put as much as possible points into Def, Rest in Power.... and survived every fight easely

(Health wasn't neccessary.. cause even with the chemicals from the chemistry club, they just get your LP down to 1 and can't damage you.)
Another hint: if you catch the molester you can get another scene with a choice of game over (enter the train, blackmailed oder stay outside.. reputation goes down, but you're able to continue to play)
Did somebody find other scenes like with the photography club?
I'm hoping for more

.
I like this game, this is fun.
