Learn English with Luka

Rin and Len meet the new Vocaloid singer, Luka Megurine.
Luka has a special talent, she was programmed to sing in English, so Rin and Len try their best to have a conversation with her.
But Miku comes in, hungry for dinner, and as Luka rambles off a list of Japanese dishes they can eat, the twins soon find that Luka's Japanese isn't that bad either...

Now Luka doesn't always look like a creepy and cute octopus. Here is how she looks 90% of the time:

As you can see, they've ditched the school uniform-type outfits for this Vocaloid2 character, as she is 20 years-old, or so we're told.

Her videos have become quite popular on Nico Nico Douga just after her recent release.
