Who's Gyokuro Shuzen?
Also, does Tsurara carry guns on her person at all times (tucked away in her kimono, presumably)?
As previously noted, Gyokuro Shuzen is Kokoa and Kahlua's mother, and therefore, Moka's aunt/stepmother (Moka's father, Issa, has multiple lovers).
I don't think it's ever clearly stated where Tsurara keeps the guns she carries on her person. A Gatling gun, for example, is too damn big to fit under one's clothes, and a sniper rifle is... probably not easily hidden under a kimono, even if you are carrying the disassembled parts of one. Magic, maybe? We do know dimension-shifting abilities are known in Rosario + Vampire.
