Firstly, it is "Ichigo" not Itchigo....... secondly please capitalize proper nouns such as names "Rukia" "Isshin" "Soul Reaper", "Zanpakutou", etc.

Lack of proper grammar could get you looked over or seen as a troll, just a heads up.

Also using the Anime as a basis for anything is ill-advised since the animators take so many liberties (and a lot of it is not seen in the Manga, making it filler information (ie: Tier's Vasto Lordes form, Ichigo's multiple full Hollow transformations, etc) While yes Engetsu can use the Getsuga Tenshou, it could be said that any other Shinigami who can mold and manipulate Reishi could in turn use it in a similar manner and call it the "Getsuga Tenshou", We do not know exactly how Isshin used it and use it frankly more powerful than its creator, but I don't think it is a family linked trait, simply a coincidence.

Also until more information is released, the speculation about Isshin's usage of the Final Getsuga should remain as unsaid speculation due to the fact that it was only revealed that he learned it not that he used it.
