Affinity

Affinity is a relationship system used in a few games. Having high affinity with various characters rewards the main character with various items and cutscenes.

Tales of Xillia 2
in Tales of Xillia 2, Ludger Will Kresnik can raise his affinity level with the other eight playable characters along with three non-playable characters: Elle Mel Marta, Bisley Bakur, and Julius Will Kresnik; however other playable characters cannot raise the affinity with each other. The best way to raise affinity with characters is threw the choices system; some choices demand to favor one character over others (or in some cases several characters), are indifferent of choice as they raise affinity with a certain character regardless of the player's choice, or at other times they simply lead to a slightly different scene while still retaining the core story. Choice screens are the only way to raise affinity with non-playable characters, while one of the ways for party members; when a choice favors a party member, the portraits for characters for which the choice raises affinity with will appear when the choice is made. Other ways to raise affinity with playable characters is completion of character episodes, using Friendship Potions, using items in battle with Ludger, staying Linked and performing linked artes.

There are ten levels of affinity for playable characters, each level with its own rewards:

Also, a "bonus scene" may play during some scenes if an affinity with a certain character is high enough. When the affinity with the three non-playable characters is high enough at the end of chapter 15, each of the characters will give Ludger a weapon: Elle will give Pollux Twins dual blades, Julius will give Spirius Model-4304 dual pistols, and Bisley will give Spirius Surrender sledgehammer.
