Ichigo Momomiya has been studying in England alongside Masaya Aoyama since the Mew Mews' battle with the aliens wound down, while Mint, Lettuce, Pudding and Zakuro handle the occasional leftover Chimera Anima in Tokyo. When Ichigo comes home for a short visit, the others plan a welcome party at Café Mew Mew, and Berry Shirayuki is part of the group too. Trouble finds them on the way: a snow leopard Chimera Anima fuses with a train, and the Mew Mews have to deal with it before any celebrating can happen.
