Irina Lan Mei (Reenie)
Generally quite a grumpy lady, Reenie is rarely seen without her little white dog, Mr Whiffles. When Masha mocks her for this, she goes into grand displays of emotion and accuses Masha of being cruel.
She abhors swearing, and the others have learnt to ignore her complaints, though they suspect she uses this to hide a past she would rather no one discovered. Reenie is afraid of robots.
