ADRIAN TUESTA 101

This show honestly at least the anime I will have to fully read the manga has serious retcon maninly it has to do the the Great dog demon toga and the sword tessegia and tensegia.The orginal show did also have problem with toga powerscaling but it didnt retcon anything serious.Mainly in the orginal show were told that toga forged the tessegia in order to protect inuyasha mortal mother and later around the same time he also had totoasii forge tensegia.But in yashhaime they are flashbacka that show toga hundreds of yeara before inuyasha mother was alive with tessegia and tensegia long before they were forge so they completely retcon that other issue.Is in the orginal manga and final act anime it waa told toga use tessegia to steal the medio techinque form shinki but was not able to fully master which is why he forged another sword tensegia and transfer that ablity fo the tenesgia from the tessegia to give sesshamraru the tensegia so he could master it and transger back to the tessegia but in the mew show they are flash backs that show toga using a peefect medio with tessegia and tensegia was already forged?
