User blog comment:Leland Davis/What I have read so far in "Trouble Twins"/@comment-4449950-20160523014720

Actually, the twins are the Gajevy twins, Yajeh and Shutora Redfox. The boy apparently laughs like Gajeel and both twins aren't scared of Natsu and when asked why reply "Because our dad is scarier. He scares people without even speaking." (thanks to estella-may for the excerpts and names)

Lol, yeah, Gajevy is confirmed canon in a side-story light novel XD But future Asuka and Romeo do appear in the story to come get the kids and stop a bad guy who summons dragon bones or something(?).
