Laxus seems to acknowledge the power of his S-Class colleague Mirajane Strauss, having seen her Satan Soul spell in use before the supposed incident which left her in a weakened state. After she showed her Satan Soul: Sitri during her match against Jenny Realight, Laxus went as far as to state that Mirajane and saying "isn't someone you want to piss off". In spite of this, he initially didn't have qualms acting towards her like he did with most of his guildmates, speaking scornfully and turning down the requests of help for the guild coming from her. While Laxus' initial overbearing behavior and disdain for guildmates made her angry, with her going as far to tearfully say that she couldn't believe someone like him was a member Fairy Tail, she was also shown to care for her fellow S-Class Mage, happily winking at her brother Elfman at the prospect of having Laxus back in the guild after his excommunication. During the Grand Magic Games she is usually seen by his side, and in his battle and victory against Raven Tail, Mirajane is seen ecstatic over Laxus, more so than any other guild member. Mirajane has also shown to care a great deal about Laxus' well being as shown when she sat by him and watched over him after he had been poisoned by Tempesta.
