Ecchi and Action Combined in Manga
Intense battles, powerful moves, and strong enemies--these are what make a manga into the action genre. Panty shots, busty girls, and clumsy perverted scenes--these are what make a manga into the ecchi genre. Combine these two genres, and you get the best of both worlds. When there's action, there are exaggerated movements, and when there are exaggerated movements, there are lewd moments.
