Much like it's predecessor, Artificial Academy, Koikatsu's chat system is the main way to get closer to the girl you are interested with. The player will have 5/5 chat interactions on each school's period. Active interactions and Girl's initiation are not counted. To start off, it is advised that you use reactive chat.
These does not consume chat interactions but it does contribute on raising Love or H Rating. Spamming the locations will lower the girl's favorability, so it is strongly advised to stop when the girl said to stop. These Active Interactions are refreshed each time the Player starts a new conversation with the girl.*
|Touch||Touch the Girl. There are 4 touch locations: Head, Lips, Breasts, and Hands.|
|Look||Look at the Girl. There are 2 look locations: Face, Breasts.|
Below are the details regarding the parts' effect on relationship:
*Note: using the potential game exploit, you can max love points in just one school period by repeatedly starting and leaving conversation without ever using the 5/5 chat interactions.

H Rating: Willingness to have H. Starts from a value of 0 to 100. When fully maxed it glows in white pink (after fulfilled the girl's invitation e.g. lunch).
