First, don't watch this if you haven't watched Love Hina, it'll spoil some stuff. Story: This special will give a nice backstory for Motoko, you'll met her sister and learn some stuff about her past. All your favorite characters will be there to give a mix of shonen, comedy and echii. This episode focuses on shonen action between Motoko and her sister witch makes me wonder if it'll be a good idea to make a anime about Matoko. Art: I'ts slightly better than the original, though i'm not particulary a fan of the artwork, probably because its better in the manga. This special will give lots offanservice in the form of pantyshots and even a bare butt. I don't think anyone would mind.

Sound:
Same music as the original, though I think they re-use music too much, especially the main theme.

Enoyment:
Enjoyed it as much as other episodes from love hina. Nothing much to add

Overall:
I'm giving it a 7, just as the original. The story is not too special but the characters are superb. Must see If you liked the original.
