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 can lower the girl's favorability and increase anger (up to 100, after which she will end the conversation Angry and break any date scheduled.) 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/Hair, Lips, Chest(2), and Hands(2).|
|Look||Look at the Girl. There are 2 look locations: Face, Chest(2).|
Below are the details regarding the parts' effect on relationship : [Note: this is a rough guide, favor and H changes can vary widely by personality]
*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.
Start a topic to discuss with the girl. Choosing the wrong topic that didn't match the girl's mood could lower the love rating. Each Personality has a different preference on a Topic. (e.g. Lady personality dislikes perverted topic)
Useful note about Girl's size if asked: x<30 (Small), 30<x<70 (Normal), x>70 (Big/Tall)

Love Rating: From Acquaintance to Friend, From Friend to Lover. Starts from a value of 0 to 100. Successfully maxed the first becomes friend, the second will give the chance being confessed on. Losing points completely while being a lover, gives the chance for the girl to ask to break up.
Girl with friendly trait will have a big likeability boost when interacted with, the friend to lover increase remains the same (easier to be friends with)
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).
Girl with slutty trait will have a big H boost just by look/touch them with/without Love Rating not being so high.
