Pretty good idea, would love this Yamato over another wave of worthless kimono, swimsuit, summer, winter, festival or whatever pointless characters.

Irremovable barriers should exist, since current days there are so many ninjas that remove barriers that its basicly character having no passive. (not talking just 1vs1 but also db/gnw)

Not completly overtuned like Minato's barriers but weaker effects - consistent irremovable barrier that basicly enables your team to work is something I wanted for a long time. Argument that this should not exist cuz it stops whale minato barrier is as pointless as saying minato mystery should not interrupt cuz it stops Madara mystery.

Good example of such barrier would be new BT Edo tensei Madara barrier, gives you some control over the fight and applies strong poison for you. Should be irremovable and that would enable some cool teams but since we can remove it easly its useless.
