I was wondering if Sasuke can KILL Himself,and delay izanagi on his body for some days(Like what Madara done against Hashirama ).While Sasuke is dead and in spirit form,he can use his sharrinegan to enter the dead world of narutoverse (like what obito did with kamui) . Sasuke will use his sharinegan to obtain jutsu from formible dead shinobi ,and possibly fight Hagaromo or any worthy Ōtsutsuki family there.I sure Sasuke bored of being supreme shinobi/so6p by now.I think this will keep him entertain.PS ,Kishi please make this come through
