Much like it's predecessor, Artificial Academy, Koikatsu's chat system is the main way to get closer to the girl you 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. It is 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.|
Proactive Romance Chat
*Note: rejecting the girl's invitation (e.g. study) will remove the ability to invite her.
|Lunch Break||Invite for lunch available|
|Club Break||Invite for club activity available|
|After School||Invite to go home together available|
|Sleeping||NPC bubbles will appear "zzz"|
|Angry||Apologize option available|
Favorability 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, give the chance for the girl to ask to break up.
NPC with friendly trait will have a big Favor boost when interacted with.
H Rating: Willingness to have H. Starts from a value of 0 to 100. When fully maxed it glows in white pink (fulfilling the girl's desire).
NPC with slutty trait will have a big H boost just by look/touch them with/without Love Rating not being so high.
More positions will be available depends on the Player's Progress. Some positions are unlockable through the story only. (e.g. cowgirl)
There is only a mini version of forced H in Koikatsu. This is meant that this game is for casual H players.
This option will appear blue on bottom right (inserting without the girl's confirmation), just below the pink option. (normal insertion)
There is no pregnancy in Koikatsu, it is just a dialogue change when doing H. This is meant that this game is for casual H players.
