A.k.a. Katsuhiko Maeda MGMMSX Web (17) Wonderland Falling Yesterday World's End Boyfriend World's End Girlfriend
Name used by World's End Girlfriend (aka Katsuhiko Maeda) when playing keyboards. It is a play on the initials "WEG", wherein the G could stand for both "Girlfriend" and "Guitar" (Maeda's primary instrument). And so, as a joke, the G was substituted for a K when being credited for playing Keyboards.
