Part 2 to my first part
Nagi+barou+bachira= using all of these 3s abilities, make an all round weapon, victory vision, randomly throughout the match an idea will pop into isagis head, hes can see the most direct path that will garuntee him a goal, but the path is like rins puppet tecnique, it shows him exactlt what to do, life here, dribble like bachira here, almost showing him and image of what he needs to do, it predicts what others will do, so he will know if he should pass, or do anything. You know in those racing games, where kt shows a ghost with a path, showing how thdy got the fastest score, think of that, but in isagis flow colour I know this seems stupidly op, but hes the fuc**** mc, the creator has spent more time on every other character. Infact this could be his flow, just like how rins was basicly just "full counter", but isagis is kings visions
So yeah, there is so much that could be done with isagi, but the creator want do anything sith him except give him the same stuff as everyone, give meta vision to everyone why dont ya!
On a side note, if you did read to here, this is another short theory i thought of
Kira will come back, think of it! Kunigami went to wild card after losing, but after seeing kiras ego appear after losing, i think thats what ego-san was looking for (saying ego-san becausd i say ego when i mean flow because thats what flow is) but kira hsd the skills to do great in blue lock, maybe even do well against the u20!
