Although the series is based on RPG style there is nothing that needs an explanation while watching as the moves and skills are named dictionary appropriate (that is you can understand exactly whats happening even if you've never played an RPG game before) The original language of the series is Japaneses i will recommend watching the English dub as it is well interpreted. it has excellent character development even what seemed like fillers have come to play huge rows in the newer seasons begging to differ its intent. all round i cant wait to see what happens next.
