Kimagure Orange☆Road: Tanabata Special is nothing more than a recap episode of the first cour. Moreover, it's a video only made available to Japanese viewers. (Thanks to the kind soul who have made this video available.) That's why I cannot recommend it to all but the dedicated fan of Kimagure Orange Road. There's no English subtitle available, just their Japanese voices. On the other hand, if you're a fan of KOR, you might not mind as, by this point, you've already seen the episodes. So you can understand the context of what is being shown despite not exactly recalling the script. Anyway, the net effect of watchingthis video is a trip down memory lane, so to speak: on how Madoka and Kyousuke met, how Hikaru saw his power and fell in love with her, entangling Kyousuke in a love triangle, etc.
