How do Natsu and Happy get into Lucys house? Just wondering but how does Natsu and Happy end up breaking into Lucy's house? I am wondering on this since I heard a recent rumor that...


  Mirajane has a spare key to Lucy's home and often gives the key to Natsu and Happy


I also wanted to ask this question since when Lucy comes home or gets out of the shower, Natsu and Happy seem to be there. Of course though it is only a rumor, but is there anything to go against this or any information to say this is true or not? I trust this site so that is why I am asking it here.

Answers are appreciated. :)
What you have heard is not a rumour, this reason is mentioned in Fairy Tail manga volume 6 Q&amp;A. 


  Mirajane has an extra copy of her house key which she gives to the other members so that they can enter Lucy's house.


I don't have a copy of this volume now so I cannot confirm it myself, but it has been posted on the Fairy Tail wiki, and a number of other sites.
