You have forgotten one rule: Law of Conservation of Information. Names and abilities of certain techniques are invariably known by every character, but are never revealed until the technique is used. However, these techniques are referenced often in incredulous statements. Ex: "They can't be using that technique?!"
This is one reason why anime rules. I think it has something to do with the fact that anime heroines are best able to contemplate their thoughts & feelings while bathing. It wouldn't have ANYTHING to do with the ability to toss in a little gratuitous T& A for ratings!
Yep!! This was also one of the weird things i noticed. And they also make the one scene, where the at least one of the male characters in a show, takes their shirt off. O.o In every anime!! One male character takes their shirt off, in at least one period in the show.
