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 4 chat interactions with a girl (or 5 if the girl is their lover) during each school period. Passive interactions and Girl's initiation are not counted. To start off, it is advised that you use reactive chat.
These do not consume chat interactions but do raise Love or H Rating; the amount depends on traits and personality. Spamming the same location can lower the girl's Love and increase anger (up to 100, after which she will end the conversation Angry and break any date scheduled.) However, Passive Interactions are refreshed each time the Player starts a new conversation with the girl.*
|based from a total of 6 unique reactions by each location|
|Touch||Touch the Girl. There are 4 touch locations: Head, Face, Chest, and Hands.|
|Look||Look at the Girl. There are 2 look locations: Face, Chest.|
Below are the details regarding the parts' effect on relationship :
[Note: this is a rough estimate, 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 chat interactions.
Unlike Passive Interactions, each Active Interaction consumes 1 chat interaction, but they have a higher impact on Love and/or H Rating. These interactions are the main way to progress quickly into Lover status and maintain it.
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)
Table of Girl's sizes if you are asked what you prefer:
*Questions from the girl's nature always have the affirmative answer on top of the negative (e.g. "I like sweets"/"I don't like sweets"), regardless of how the auto-translation looks ("No eye"/"Sweets such as sweets").
**Body size is determined by the average of "Waist Width" ('Lower Body' tab) and "Lower Torso Width" ('Upper Body' tab), rounded down. The skin type "Chubby" has no effect on this.
|Confess||Tells a character that you love her. Lover relationship will establish if accepted.|
|Break up||Break up lover relationship. Results in upsetting the girl.|
|Invite to date||Invite the character on a date next saturday. Be careful, you can only date one person at a time. Not fulfilling others' date will get them upset on the next day. The girl will not be upset if you are doing Story-related date on saturday, and the promised date will be postponed the next week.|
|Invite to join club||Invite the character to join your koikatsu club. One of the main goals in the game.|
|Invite to H||Ask the character to do ecchi with you.*|
|Invite to Lunch||Ask the character to eat lunch with you.*|
|Invite to Study||Invites a character to improve Wisdom score with you in the library. Increases Wisdom by 1-3 unconfirmed*|
|Invite to Exercise||Invites a character to improve Strength score with you. Increases Strength by 1-3 unconfirmed*|
|Walk home||Ask the character to walk home with you after school. Option to invite the girl over for H is available if a lover. For more info, see Events|
|Apologize||Apologizes to the character who is currently upset. Other interactions will lower Love Rating.|
*Note: rejecting a girl's invitation (e.g. to study, to go on a date etc.) will remove your ability to invite her to do the same for the remainder of the period.
Love Rating: From Acquaintance to Friend to Lover. Starts from a value of 0 to 100. Successfully maxing the rating the first time becomes friend, the second will give the chance being confessed on (or you can confess). 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.
