Futari wa Milky Holmes

Synopsis

As Alice and Kazumi take up part-time jobs to fund their Feathers activities, Alice takes note of an old lady who seems to come to the same bar by every day. Curious, they decide to follow the old lady on the bus and eventually runs into her, where she tells them about how she often goes on the bus to meet someone. The next day, Alice and Kazumi notice something off when they spot the old lady going off with the bar master, deducing that she is in fact a phantom thief named La Lunar, who uses deception Toys that allow others to perceive her as different people. After Alice and Kazumi manage to stop La Lunar, the girls realise the person the old lady keeps meeting with is the bus driver, who is actually her estranged son she was working up the courage to talk to.
