All of Building 13 are totally Fairy Tail guild member material. Breaking everything.
Especially Hajime. Who breaks everything, including poor Jyugo.
Then Building 3 is obviously Blue Pegasus.
Building 5 is Lamia Scale and, I guess Building 4 would be... Sabertooth? With Musashi being the Sting and Rogue to Jyugos Natsu and Gajeel?? Maybe.
Momoko is Mermaid Heel! And Mitsuru is Quatro Puppy XD
