Unfortunately, he can't figure out which one of the five girls chasing him it was; but he gets plenty of chances to find out the color-of-the-day in his Cinderella search for his one true love!
Both are well executed high school harem comedies with the male leading being a lot more likeable and less perverse than most. Ichigo is more realistic and dramatic, while Rosario is more supernatural and comedic. Ichigo is the superior show by far, but if you found one entertaining, the other will probably satisfy as well.

On February 10, 1904, Japan entered a war with Russia; but Japan, in order to turn the tides, must destroy the Russian Pacific fleet before it is able to bring reinforcements. Battling on the front lines are brave men and women, and a secret team of specially-trained young girls who can control Raimu spirits with their will: the Raimu Unit. Enter Shintaro Umakai - a teacher who has accepted a job aboard the battleship Amanohara to teach the Raimu unit; however, Shintaro discovers his job has far more duties than he first anticipated: he must have sex with the young Kuki so the ship can awaken, he must dodge the sexual advances of his students, he must avert his eyes from Momen's constant accidental panty shots, and most importantly he must assume the role of their new commander once their old one is whisked away by the enemy. There's a war going on - what's a guy to do?
"Rosario to Vampire" and "Lime-iro Senkitan" are both similar, yet different. The male lead has a new school to go to (albiet one is a teacher, the other a student) which is situated in a strange location. Their school isn't what they thought it would be at all and on top of that, there are a few girls who like them. These two series are both very entertaining and despite being only 13 episodes long, there's plenty of room for character development for everyone (that matters) as well as following the main plot of the story. Long story short, watch one if you liked the other and you'll attain satisfaction.
