1) The best way is to do sub-events with the character you want to raise relationship with. For example, if you want to raise relationship with Kratos, talk to the guard standing to the right of the government building in Palmacosta, and ask Kratos to train you. There are many sub-events in the game to help you raise relationship.
2) The way you answer questions also adjusts relationship. Almost every question you are asked to answer adjusts relationship. In general, logical and conservative answers will please Raine and Kratos, while emotional responses have a tendency to raise relationship with Colette and Genis.
3) There are 20 skit points on each world map (marked by a glowing blue circle). Each skit point involves one particular character in the party. Lloyd will be posed a question, and the way you answer it will affect the particular character’s relationship. It is usually easy to tell which response will make the other character happy, and which one will tick them off.
4) Have Lloyd cook recipes for the character that involve ingredients he or she likes. For example, Colette likes fruit, so cooking any recipe that has fruit in it, like Shortcake, will make her happy each time it’s cooked. On the other hand, Colette does not like Bell Peppers, so having Lloyd cook something with Bell Peppers in it will lower his relationship level with Colette. Remember that Lloyd must do the cooking!
