Hi (Trailblazer), the name's Serval Landau, I'm a Belobog mechanic. Of course, that's really just what I do on the side — rock 'n' roll is my main occupation.

If you wanna make sure you don't burn yourself out or stifle your creativity, then don't push yourself too hard at work~

Since I do rock 'n' roll full-time, I'd say my hobby is... work? What's wrong with that?
