Tokyo Mew Mew a La mode is obviously the sequel to Tokyo Mew Mew. It's when Ichigo goes with Masaya to England to study and a new mew mew steps in for leadership.
Berri, a blonde happy girl who adores fashion transferred to a school in Tokyo just for it's uniform. She stumbles upon Cafe Mew Mew and wander accidentally into Ryou's lab.
There she gets injected by 2 animal genes by Ryou with a needle and she faints shortly afterwards. She soons learns that she is a mew mew but as the Saint Rose Crusadors discover, she is more powerful than Ichigo and they need her blood.
So the Duke, one of the people in the gang poses as a teacher at Berri's school. There he tries to kiss her and take her blood. He doesn't, however succeed.

Later on the Saint Rose Crusadors have managed to turn everyone anti-mewmew.
Just as Ichigo arrives back in Tokyo the 6 mew mews have to fight against the crowd.
People are putting up signs and chanting down with mew mew and saying that the mew mews were good before the white mew mew came along. She must've turned them evil and things like that. Meanwhile, Berri has problems of her own. Tasuku her best friend and later on boyfriend has been turned into one of the villains and is trying to kill Berri.
Luckily Berii and Ichigo team up and use the attack Ribbon Double Berry Check (I think that's it or I may have got it wrong. It was ages since I read TMM a La Mode) and they manage to defeat the Saint Rose Crusadors and then with Berri's power of love she kisses Tasuku and he is pulled out of the darkness.
