BS and izanagi are two different jutsu. BS can create THINGS frm your imagination and make them real. Izanagi can only be used on urself. You can trap yourself in a fantasy world that's real fr you like danzo said sme guy did. Or make you death a illusion. The second you CREATE something, your nt using izanagi, that's BS. The concepts are kinda the same as far as illusion into reality. But what you can do with the techs are completely diff. Neither tobi or madara can create a 11 tails bijuu with izanagi. You need the ability to use BS fr that. The sage didnt make bijuu with izanagi...he used BS. That's the diff IMO. Like a fire ball tech and Amaterasu are diff...yea there both fire techs but the scale and power are diff. Bad example but that's the gist... I think what u guys are saying is izanagi is a lite version of BS? I get that but..no. There just two diff things. A better example: sasuke and itachi both have tsukinami. Same tech but completely diff scales. Night and day. At the end of the day tho they're both tsukinami same name. If izanagi was just BS lite...it would still be called BS. They would just explain that the sage could use it on a completely different level, far beyond uchiha because of blah blah blah. That's nt how it went tho. Uchiha have izanagi, which comes frm BS but is completely different in application, power and ability. So it's nt the same tech at all
