It was a normal day in the guild and everyone is causing fights.

Lavender was sitting at the bar of the guild when she started to feel weird, Mira and Lucy took notice and Lucy felt her head. "Oh my god, Mira she's burning up" Lucy said concerned and helped lavender to the infirmary and Mira told lisanna to take over till she got back and went with Lucy and lavender.

Meanwhile gajeel was looking for all the dragon slayers, he found Mira and asked her if she's seen lavender, natsu and laxus. "Oh, lav is in the infirmary and natsu and laxus are by gray and thunder legion." She told him and he left to go get the two males and told them to go to the infirmary.

"What why?" Natsu asked confused and laxus was as equally confused. "Just do it salamander, you too sparky" gajeel said annoyed and left to go get sting and rogue.

Natsu and laxus looked at each other confused on what gajeel wanted and went to the infirmary and found lavender in one of the beds. "Whoa, what happened?" Natsu asked concerned and Lucy was next to her. "She was burning up out of nowhere so me and Mira brought her here but then gajeel came to me and told me to stay here, for some odd reason" Lucy explained and now they were officially confused "he told us to come here as well" laxus said and now they were curious.

"That's weird, lav, you feeling okay?" Lucy asked and lavender nodded. "Yeah, but it was so sudden I don't know what happened. I hardly get sick" she said as she crossed her arms, frustrated.

Sting and rogue came in the infirmary looking confused, "why are you two here?" Natsu asked as the others looked as well. "That's what we want to know, gajeel came and told us to come here" sting announced and now everyone in the room was puzzled on what gajeel wanted.

'what does he want and why did he call all of us here?' the all wondered and then gajeel entered the room. "Gajeel, why is everyone in the infirmary? And why are sting and rogue here?" Lucy stood up as well as lavender even after Lucy told her to stay on the bed.

"So, you know how everyone in this room is a dragon slayer?" Gajeel asked and everyone nodded. "Well, how should I put this..?" Gajeel wondered then sighed, "well its the time of year for dragon slayers and we are in mating season" gajeel announced and everyone but him was stunned.

"Mating season?!" They all shouted confused and gajeel nodded.

"What? How?" They shouted and looked at gajeel for answer's. "Look all I know is that it's that time of year for dragon slayers and that we go through heat." He shrugged and lavender took a step forward. "Are there side effects of heat?" She asked and he nodded. "Yeah, but I think for females their bodies feel hot and causes headaches" gajeel said and Lucy, natsu and laxus looked to lavender. "Please tell me your joking..." She asked tensed and gajeel shook his head. "Not from what I heard from the old man, no why?" He folded his arms with a raised eyebrow at her and she sighed "I think it started for me already, not too long ago my body started to feel hot and Lucy said I was burning up and then you told us about mating season" she frowned and covered the blanket over her head while standing.

"That's not good..." Gajeel silently cursed under his breath after finding out that one of the dragon slayers heat started already. "Okay, so, we have a slight problem" gajeel announced and everyone looked at him and lavender lifted the blanket to see him. "What problem?" Sting asked and the others nodded. "No one here knows who their Mates are" gajeel said and everyone went silent.

"............we are on trouble..." All the dragon slayers said In union
