Guys... are you trolling or talking out of ur ... ? What Kakashi Kimono removing? Shisui can't be debuffed like 6p Pain so what debuff are you going to apply on him dude? Typical forum experts, saw ninja only on youtube, has no idea how he works but first to comment.

As for Obito it's plain impossible as well, you are dead round1 (at least your backline most of the time is) and round 2 unless guy has 0 IQ he just kills this time backline for sure or to be safe locks Obito mystery (not to mention that you have to trigger Shisui's dodge first too yeah good luck with this idea) so your perfect easy counters to "everything has a counter" simply don't work.

FelineSeven is sadly right,

this time there is no counter to Sus Shisui. He is so broken that they covered everything. There are only 2 ways right now to win vs somewhat equal power Shisui with out using him yourself:

1) BT Danzo Izanagi 1shot team (needs strong backline so with hidden buff shisui cant easly lock your mystery r2)

2) Base Hiruzen with pos1 Edo Zabuza who at least can do something with his own multiple standard attacks since we cant use mystery at all.

Special reward to Teemonly, trying to sound smart with 0 knowledge about the game always brings good laugh.

If you have him just try him, don't care about ignite or enemy control. LM gives protection vs basic one and your Zabuza (if your pos1 is stacked) kills enemy backline before they can drop linked chase combo anyway. VS like you said 30% weaker Shisui setups that can beat you now Zabuza will win. There is no other reliable setup, its as good as you can get.

Indra, oro and jirayia works only in arena (in arena he is not a problem anyway) so that's not a solution at all, you will get absolutly rekt with those 3 in normal fight

Thats probably why, at your power pos1 ninja are not stacked yet compared to backline so Shisui is not deadly 1shotting machine. When he has 20k+ more injury than backline ninjas his few standards are enaugh to instantly ruin your day round 1.

EDIT^ Destroying backline can be done by other ninjas as well but Shisui ability to lock enemy mystery and in general dueling potential is too broken to come back against that in a fight. 6p Naruto nuked backlines too but you could come back from that with Madara etc, vs Shisui there is no coming back xd
