Fairy Tail Wiki:Relación Seis/Thunder Gods

Gray Fullbuster
Cana and Gray Fullbuster have been friends ever since they joined Fairy Tail in their childhood, having done so in the same period. As children, they were often shown to be together, with Cana using her cards to try and read Gray's fortune, as well as pointing out when the boy inadvertently removed his clothes due to his stripping habit. Each of them recently stated to be on good terms with the other during their respective interviews for the Sorcerer Magazine. Gray is often shown to joke around with Cana, holding back laughs when telling the girl that her Edolas counterpart was completely different from her after returning from the alternate dimension, and later pulling her leg about her newly-found relationship with her father Gildarts Clive.

Macao Conbolt
Cana and her older guildmate Macao Conbolt are said to be drinking buddies. They get along with each other very well, considering themselves great friends, and, at some point, Cana even became infatuated with Macao, going as far as to decrease the amount of alcohol she used to drink when advised to do so by him, only to subsequently double it after Macao got himself a girlfriend. The man is shown to respect both Cana's fighting spirit and her alcohol tolerance, considering the latter unmatched; when Bacchus defeated her in a drinking contest and took her bikini top "as a trophy", Macao angrily rushed to Quatro Cerberus's S-Class Mage in an attempt to punch him and protect her friend's honor.

Loke
While almost no interactions have been shown between them, Cana and her fellow guildmate Loke are on good terms, and were said by Mirajane Strauss to work as partners in the past; during the war which ensued between Fairy Tail and Phantom Lord, the two of them were shown fighting off enemy Mages back to back while assaulting Phantom Lord's building in retaliation to the rival guild's attack on team Shadow Gear, and later led their comrades against Jose Porla's Shades together while defending the guild.

Laxus Dreyar
Cana wasn't too keen on the arrogant and overbearing demeanor which initially characterized Laxus Dreyar, one of Fairy Tail's top S-Class Mages, angrily telling him off when Laxus refused to help his guildmates out during their confrontation with the Phantom Lord guild; the man, in turn, said that he would have done something only if Cana had stripped for him, hinting at some perversive tendencies towards her. Following Laxus' excommunication and his subsequent return to the guild, with his attitude having gotten less arrogant and friendlier, the two of them seem to be on better terms, as shown from Cana cheerfully drinking with the S-Class Mage and his Thunder God Tribe during the party taking place after the first day of X791's Grand Magic Games.
