Episode 3 I think....
In the Tokyo Mew Mew series, Kisshu kidnaps Ichigo in Episode 11, titled "A Forbidden Love? The Geeks' Love Is Dangerous." This episode explores the complicated dynamics between Kisshu and Ichigo as their feelings begin to evolve.
episode 3. and its not zoey and dren, its ichigo and kisshu. zoey and dren are from mew mew power. mew mew power is americanised. Tokyo mew mew is the original and also has more episodes. and dren/kisshu kissed zoey/ichigo
Kisshu from Tokyo Mew Mew is a boy. He is one of the main antagonists in the series and is a member of the alien race known as the "Aliens."
no
In episode 24, Ichigo had accidentally fallen on top of Kisshu (^w^) when trying to stop him from teleporting with the Rainbow Stone.
Dren, but I prefer to call him Kisshu, comes back to life in episode 52.
In the anime Tokyo Mew Mew, Kisshu (Dren) technically kissed Ichigo (Zoey) in episode 3, but there was a flashback of the kiss in episode 4. ^^
He seems to already know the first time he met her.
In Tokyo mew mew Kisshu poisoned the trees in inohara park in episode 12 The name of the episode is called "Identity Revealed - An Out of Season Cherry Tree Falls Away""Barechatta, Kisetsuhazure no Sakura Chiru"(バレちゃった、季節はずれの桜散る) (In Mew mew power it was episode 1/premiere episode - The Main Mew's Muse" )
He doesn't nearly die, he does die. He dies in the 3-part-final; Episodes 50, 51 and 52. I recomend you watch it, its really good. :) ~dawnredd
