maybe doing your first playthrough on easy mode and equiping the autoguard ms part could let u stand idle to read the dialogue with not much risk but yes unless u can pick up some japanese by ear its pretty much imposible to read mid battle

fairs, i have tried out the auto guard on one of my Mobile Suits but it didn't seem to do much

i gave it some thinkin and it probably doesnt work for u because autoguard by itself still needs u to face the attack if it hits u from the side or back it will go through but theres a modification that lets u do omnidirectional block a bit of an RNG solution but if u find a piece with it mix both mods and try it out. You would still be defenseless to some attacks particulary any grappling but i think its doable if u use high HP units on easy mode. Blocking in this game doesnt mitigate all the damage so i still recomend to move around with dashes randomly while reading cause it has some invencibility frames built on and as long as u dont attack or jump the autoguard will trigger while performing a dash. Or maybe just watch a playthrough on youtube for those specific dialogues hope u find a way to also enjoy the story cause i thought it was kinda bad myself, have a good one

ah
