Serval is a cool-headed, free and rebellious woman who is the owner of the Neverwinter Workshop in Belobog. Her real name is Serval Landau and she's the eldest daughter of the Landau family. Serval was also once an extremely close friend of Cocolia, who is Belobog's Supreme Guardian, before she got dismissed from her previous position as an Architect by her after certain events. Serval has been living as a mechanic since then, going around and performing rock 'n' roll concerts occasionally.
