What should I do if I want to meet hitomi ?
Hitomi becomes available after passing through the plot of some missions. The main interactions with her open just when there is a meeting for the introduction of an independent newspaper at school.
Thanks
By the way where can I spend club money, except for occult club?
You can exchange them at Yuki's for regular money, which you can spend at the grocery store/online store. Roughly speaking, you can launder them.
