Maybe because the guy had his best gear in move 4 and he is not aware of it. If the difference between his real move 4 initiative and your real move 3 is higher than 10k then he moves before. Lets say in matsuri his move 4 has the stats of his equipped move 1 and owns 18000 initiative, if your real move 3 has 6000 initiative then he is able to interrupt you.

Happens to me always. Welcome to mystery delay glitch. In my case, pos 3-4 of the enemy goes before my pos 1. All my ninjas have ini advantage. Seen a lot with danzo, kurunei and wind main.

In matsuri units get the average of your total stats (minus treasured tools), so it's highly unlikely...

EDIT: I was replying to Scarlettblue.

naa bro, the guy even had less ini than me on his 4th move than my 3rd... Like i know this usually happens with delay, but never have i been interrupted like that lol, when it delays like the guys do their interrupt moves and it's like the interruption failed cause of delay in theory i activated it after them... But now no! my 3rd move now actually was interrupted by his 4th not allowing my kushina to leech life and then she died... This game is screwed man... And now controls are failling left and right! It was super rare for the controls to fail, now happens everytime, yesterday my opponent failed his control on me during space time... This kind of stuff used to be so rare lol

That's what the team said to jiburiru but not what we all see that happens for real. If this was true would be close to impossible to see move 2s with inverted order in comparison with move 1s to not talk about moves 3s vs 4s and i am sure it never happened to you while facing people stronger than you by far (to me happened two times yesterday out of 6 battles and is not that my move 2 treasure tool is so op... but i went ahead the same).

What happened is that your mystery was delayed. You were not actually interrupted but, server side, your ninja died before the server received you mystery input so, even if your ui showed you the icon of your mystery in truth the mystery was not calculated in.

no man, my ninja was actually interrupted... kushina only died after his 4th move did standard attack... I saw my kushina get stopped by the lightning seal...

i'm done playing this. Again my mysteries don't go during sage costing me the matches vs some degenerates. Sick of this. They don't fix it? that's fine. i'm DONE

Can you tell us how they were placed on the field your and his ninjas? I begin to think maybe the enemy main was not in 4th prompt move (moreover because there are not many meta lineups that put mb with acupuncture seal in move 4... )

team was placed like this (masked man in place of iruka, i don't have masked man lol)

lol didn't go the print...

Did the lighting main who used sealing slash use any sort of summon mystery like Pakkun or Shiba when interrupting you?

he uses giant katsuyu

my ninja were positioned this way, as u can see his main is 4th and my kushina is 3rd

There is one thing I noticed about summon mysteries. Once the main has clicked his mystery he will use his summon mystery before that. The thing is, the time span in where the main does his summon mystery is a point of no return. You can't under any cir*stances interrupt the main's mystery during the time span in which he does the summon mystery. When the enemy activates a mystery during that time span of no return it won't go off till the main has done his mystery. That being said, if your position 1 activates a mystery while the other main is doing his summon mystery, you won't go first but the main will. That can result in the 4th position acupuncturing and interrupting the position 1 character. In your scenario the enemy probably just wanted to do damage against your Kushina but your Kushina mystery was activated by the game during the time span in which the main did his summon mystery, resulting in Kushina being interrupted. I think I know why that is happening. The game doesn't register the summon mystery as an action before the mystery which can be used for reaction time (e.g. Mabui's 40 chakra passive) but instead it counts as part of the actual mystery. That's my theory at least.

hmmmm that's a plausible theory... but is it some sort of a bug or is it supposed to be like that?

why cant it just be simple?
If you have higher initiative, you go first

no bs, simple as that.

bc of delay, i couldnt interrupt water main and since i was fighting cancer team, that changed the match.

It's supposed like that. The summon is only triggered, when the mystery is triggered. It's triggered the same way a Chase is triggered / chained.

It is, so to speak, the same animation.

cause this game is terrible lol at least as long as things work like this
