1. Fight back
If you've been physically subdued by a Japanese schoolgirl, you only have yourself to blame. It's right up there with drowning from a nosebleed as one of the stupidest ways to die. Makoto's girlfriend probably weighed, what, about 110 lbs, 115 max? That's disgraceful. There's absolutely no excuse for being killed by a girl, unless she has supernatural powers or a gun. Guns make it way too easy for women to kill men. That's why we need gun control laws � to keep women defenseless and obedient.
You might be asking yourself how Makoto could've fought back.
There are plenty of ways: dodging the attack, parrying the blade his bare hands, etc...,
but Makoto was too much of a wuss to even try. The dumbass just stood there.
Here's a much easier suggestion:
Makoto was carrying a cell phone at the time, why not throw it in her face? BAM!
Then tell her to get back in the kitchen.
2. Eat his girlfriend's food
Makoto is a douchebag for all sorts of reasons (not breaking up with a girl he no longer likes, cheating on his girlfriend, cheating on the girl he cheated with, trying to conceal his relationships while regularly having sex on public property, letting himself get killed by a girl, etc...), but the stupidest thing he ever did was not eating his girlfriend's food. What the hell is his problem? Does he know how lucky he is? Girls never cook anything for me. Ok, maybe they do, but it's always something lame like brownies. Cook me an omelette, then I'll know you care.
You might be wondering how not eating his girlfriend's food led to his death.
The answer is simple: nothing makes a woman happier than cooking for her man
(I'm pretty sure it says that in The Bible).
It logically follows that a woman would be filled with murderous rage if
her food were ever rejected.
3. Not sleep with his girlfriend's best friends and worst enemies
If you're dick enough to cheat, at least do it with a neutral third party.
4. Be more like Makoto Nagano
If you've ever watched the obstacle course game show Ninja Warrior (or Sasuke as it's called in Japan), you're well aware of the indisputable scientific fact that Makoto Nagano is invincible. In the 10 year history of the competition, Makoto is only the second person to complete all four stages (and the only one who didn't subsequently lose his vision).
Would Makoto get killed by his girlfriend? Hell no. Would he even have a girlfriend? He might say so to keep the fangirls at bay, but the truth is that he doesn't even need a girlfriend. The whole of point sexual reproduction is to foster genetic variation and ultimately strengthen the species. Now that the perfect human being has been created, sexual reproduction serves no purpose.
Makoto Nagano reproduces through fragmentation. Fragmentation is a form of asexual reproduction where an organism is split into fragments. Each of these fragments develops into mature, fully grown individuals that are a clone of the original organism. Fragmentation is observed in nonvascular plants, as well as liverworts, mosses, and Makoto Nagano. He just chops off an arm, and it grows into another Makoto Nagano. If Makoto from School Days could regenerate like Makoto Nagano, he technically wouldn't have died.
