Sekiro: Isshin Ashina (Final Boss, Shura ending) (NG+2, Demon Bell, no Kuro's Charm, no damage)

Mist raven then dodge diagonally to the right is probably the easiest way to deal with One Mind/Judgment Cut without outright cheesing it (i.e cancelling it with firecracker or something). Apparently you can parry it with the umbrella but I didn't manage to reproduce it. Another new thing I learnt is that in P3 you only want to attack him twice after the Ichimonji fire attack, or the One mind, since he may do a quick turn slash+fire attack that's hard to dodge. To counter this you just want to get ready to Mist Raven after the two hits. Also for the perilous sweep you might not want to jump on him because he can attack you before you land which is hard to deflect or if you jump attack him twice instead, he may dodge and counterattack which is again hard to deflect. Safest thing to do is just to run away or dodge back.
