Some dumb shit I noticed about this update:
1. Alex' problem is that he believes it's too easy to kill your rival. Alright, then what solution does he come up with? Making sure the rival always out with her little clique of friends who can all perform their own reaction and each cause a game over, making it harder to get away with murder the more witnesses there are? Of course not. He creates an invincible bodyguard called "Raibaru"
2. "Raibaru"? Seriously? After YandereDev went on a full "this is not a meme game" tirade and said that he wanted to make names that sounded more legitimately Japanese? Hory shet, this isn't even difficult. What about RAIko SuBARU? Rai + the feminine -ko suffix + an actually existing last name that includes "baru". Also a quick google search will reveal that Raiko can either mean "Thunder Child" or... circumcised.
3. So YandereDev wants an invincible obstacle whom you can't overpower. Alright, fair enough... so like how the teachers originally were when they were first implemented?
This yet again reveals a consistent problem with YandereDev's worldbuilding: he keeps adding in elements he thinks are cool, not worrying about whether they make sense or whether they contradict established worldbuilding. Consider this: Raibaru is strong and invincible, yet Budo beat her and is therefore stronger. You can't even surprise Raibaru from behind due to her lightning fast reflexes... but you can face Budo head-on if your strength stat is high enough? Yandere Dev also alluded to the Delinquent Rival being the "strongest girl in school", which would make her stronger than Raibaru and maybe Budo... yet you're expected to beat her in hand-to-hand combat? And somehow Raibaru is stronger than any of the teachers too, despite all teachers having extensive martial arts training? But Yandere Dev explains some students (like "Fureddo") having martial arts training despite not being club members because Raibaru taught them some martial arts. I guess she also instructed the teachers then, I guess?
See how everything collapses if you try to make the worldbuilding consistent? The solution is simple: Just get rid of Raibaru and make the teachers invincible once again. Get rid of this obsession with exceptional individual yandere strength and just make Yan-chan an ordinary (but twisted) high school girl. Just ensure that the rivals are rarely alone (this shouldn't be difficult, real life high school students rarely dwell the school alone) and have the teachers actually do their job and patrol high density areas of the school during break (like having one teacher oversee the roof and another the area near the fountain, so they can do their fucking jobs and intervene if problems arise). Voila, an invincible obstacle (or "guard") between you and the rival. An obstacle you need to get rid of (by, for example, infiltrating the VA room and announcing that the teacher in question should report to the teacher's lounge for a special phonecall, giving you a small window of opportunity where she's not overseeing her assigned area).
Alex identifies a real problem but comes up with a exceptional "just throw something at it and see if it sticks" solution rather than retracing his steps and trying to have the world make sense.
