That would put MC into the Original Timeline, were Noriko dies and Yasuka just got broken after that and never recover after... That would be one of the possible Bad Endings. It would be interesting if
RNGeusEX add this kind of things, and moreover some complexity by adding time (days, week, months) to reach an achievement, still one of the dialogs of MC Best Buddy said meet me in 3 days, and later we as MC meet him again like after a week (if not more). Those little things to put us in the flesh of MC, after all his objective is to change not only his destiny but part of his life depends on how good the life of ppl who are near to him is ok. But if you must really hate someone, appreciate more Akira, it feels like
RNGeusEX put efforts in making a hateful character which is impossible to redeem, at least Noriko can be manage if you become dominant to her, she will eventually become passive, but with Akira... That's another story.
